Abstract:

The solar trough concentrator is used to increase the solar radiation intensity on absorbers for water heating, desalination, or power generation purposes. In this study, optical performances of four solar trough concentrators, viz. the parabolic trough concentrator (PTC), the compound parabolic concentrator (CPC), the surface uniform concentrator (SUC), and the trapezoid trough concentrator (TTC), are simulated using the Monte Carlo Ray Tracing method. Mathematical models for the solar trough concentrators are first established. The solar radiation distributions on their receivers are then simulated. The solar water heating performances using the solar trough concentrators are finally compared. The results show that, as a high-concentration ratio concentrator, the PTC can achieve the highest heat flux, but suffers from the worst uniformity on the absorber, which is only 0.32%. The CPC can generate the highest heat flux among the rest three low-concentration ratio solar trough concentrators. Compared with the PTC and the CPC, the TTC has better uniformity, but its light-receiving ratio is only 70%. The SUC is beneficial for its highest uniformity of 87.38%. Thermal analysis results show that the water temperatures inside the solar trough concentrators are directly proportional to their wall temperature, with the highest temperature rise in the PTC and the smallest temperature rise in the TTC. The solar trough concentrators’ thermal deformations are positively correlated to their wall temperatures. The radial deformation of the SUC is much larger than those of other solar trough concentrators. The smallest equivalent stress is found in the SUC, which is beneficial to the long-term operation of the solar water heating system.

Abstract:

Solar energy has demonstrated promising prospects in satisfying energy requirements, specifically through solar photovoltaic (PV) technology. Despite that, the cost of installation is deemed as the main hurdle to the widespread uptake of solar PV systems due to the use of expensive PV material in the module. At this point, we argue that a reduction in PV cost could be achieved through the usage of concentrator. A solar concentrator is a type of lens that is capable of increasing the collection of sun rays and focusing them onto a lesser PV area. The cost of the solar module could then be reduced on the assumption that the cost of introducing the solar concentrator in the solar module design is much lower than the cost of the removed PV material. Static concentrators, in particular, have great promise due to their ability to be integrated at any place of the building, usually on the building facade, windows and roof, due to their low geometrical concentration. This paper provides a historic context on the development of solar concentrators and showcases the latest technological development in static PV concentrators including non-imaging compound parabolic concentrator, V-trough, luminescent solar concentrator and quantum dot concentrator. We anticipated that the static low concentrating PV (LCPV) system could serve to enhance the penetration of PV technology in the long run to achieve the Sustainable Development Goal (SDG) 7—to open an avenue to affordable, reliable, sustainable, and modern energy for all by 2030.

Abstract:

In this research study, we have compared between the two different concentrators with the flat absorber plate receiver of the compound parabolic concentrator heat pipe solar concentrator and ordinary heat pipe flat plate solar concentrator. For the reproduction of solar radiation in the experiment, iodine tungsten lamp was used. Thermal performance comparison of the two types of solar concentrator under different simulating radiation intensity conditions was carried out with including the fluid temperature, instantaneous efficiency, average efficiency, and average heat loss coefficient. The results of the experiment indicate that the compound parabolic concentrator heat pipe-type solar concentrator not only increased the fluid temperature and instantaneous efficiency but also decreased the average heat loss coefficient as compared with the ordinary heat pipe flat plate solar concentrator. It was noticed from the experimental results that the efficiency of compound parabolic heat pipe solar concentrator was higher than ordinary heat pipe solar concentrator up to 6 and 10°C with the light intensity, that is I = 679 W/m2 and I = 892 W/m2, respectively. From the results, it was concluded that the using of compound parabolic heat pipe solar concentrator increased the thermal performance of solar concentrator.

Abstract:

The present work aims at decrease the cost of the photovoltaic (PV) solar system by decreasing the area of expensive solar cells by low cost optical concentrators that give the same output power. Output power of two types’ monocrystalline and polycrystalline silicon solar cells has been measured with and without presence of linear focus Fresnel lenses (FL) with different concentration ratios. Cooling system has been used to decrease the effect of temperature on solar cell performance. The results indicated that the increase in the output power is about 5.3 times by using Fresnel lens concentrator without using cooling system in comparison with solar cell without concentrator, while it is about 14.6 times by using cooling system. The efficiency of monocrystalline solar cell without cooling system is about 11.2% for solar irradiance 0.698 kW/m2, this value decrease to 3.3% for solar irradiance 12.4 kW/m2 and concentration ratio 17.7 by using Fresnel lens concentrator, while when using cooling system the efficiency enhance to 12.9% and 8.8% for solar irradiance 0.698 and 12.4, respectively.

Abstract:

This article examines the features of solar energy concentrators. The characteristics of the currently existing types of solar energy concentration systems are given: a weak concentration system and a high concentration system. Their design features and shortcomings are given. It is noted that Frenel lenses are one of the most widely used concentrators, but their optical efficiency is limited by low or high temperatures, as a change in the refractive index or deformation of the Frenel lens structure is observed due to thermal expansion. Fresnel lenses, which focus solar radiation on an area of up to 1 cm 2, do not allow the utilization of excess thermal energy. The complex geometric shape of parabolic concentrators determines the expensive technology of their manufacture, which, in turn, significantly increases the cost of the electric energy produced by them. Luminescent solar concentrators have a low coefficient of concentration of solar energy. The conducted analysis showed that the existing concentrators of solar radiation do not allow to create competitive compared to traditional sources of electrical energy photo-energy installations that work at high levels of concentration of solar radiation and utilize excess thermal energy. In order to solve the mentioned problems, the authors developed a faceted concentrator of solar radiation, gave its characteristics and presented a laboratory sample. Questions of optimization of the adjustment of the concentrator are investigated. A report on the mock-up tests conducted has been published.

Abstract:

The utilization of solar energy continues to be developed to get the best efficiency. This energy can be used for electricity generation, cooling, and/or drying. One technology that is still under development is the use of solar concentrators. Therefore, our paper aims to measure the performance of the development of a solar collection unit coated with mirror paper. Furthermore, the data is compared with the test data for solar concentrators without mirror paper that was carried out by previous researchers in 2019. The method used in this research is a field experiment. A simple statistical comparison method was carried out on the experimental data. Field testing was conducted after the solar concentrator was coated with mirror paper. The test was carried out for 5 days in full shining sun conditions in Sukabumi Regency, Indonesia. The surface coating of the solar concentrator with mirror paper has not been able to improve the performance of the solar concentrator satisfactorily. Solar concentrators can heat the fluid from its initial average temperature of 19.37 %. HIGHLIGHTS Several field tests were undertaken to determine the effectiveness of solar concentrators with and without mirror coated paper The fluid temperature heated with coated paper in a solar concentrator provides a higher temperature than without paper coating Solar concentrator with mirror coated paper has potential as an alternative for covering the surface of the solar concentrator GRAPHICAL ABSTRACT

Abstract:

The annular compound parabolic concentrator (CPC) is a body of revolution consisting of two axisymmetric surfaces produced by rotating a classical two-dimensional CPC around an axis parallel to the CPCs axis. Its ability to further concentrate incoming radiation when used in tandem with a primary solar parabolic concentrator is analyzed by the Monte Carlo ray-tracing technique. Potential applications are found in capturing the annular portion of primary concentrated solar radiation and augmenting its power flux intensity.

Abstract:

Solar distillation is one of the oldest and simplest technologies for desalination of salty water using renewable energy, namely solar energy, and the main problem of solar distillers is the low freshwater yield in contrast to the amount of energy input from the sun. To overcome the problem, this study develops three solar desalination units by using solar concentrators or/and internal reflectors, and compares the performance of three developed systems with the one of a conventional solar distiller under the climatic conditions of the Rabat region of Morocco. The three systems are: the solar distiller with a solar concentrator, the solar distiller with internal reflectors, and the solar distiller with a solar concentrator and internal reflectors. The energy balance equations of the systems are numerically resolved to utilize MATLAB software. The findings indicate that the utilization of the internal reflectors, the solar concentrator, and the solar concentrator and internal reflectors give better performance compared to the conventional solar distiller.

Solar concentrators improve the performance of solar collection systems by increasing the amount of usable energy available for a given collector size. Unfortunately, they are not known for their light weight and portability, which is ideal for basic applications like solar cooking. The goal of the project was to a design a light-weight and portable solar concentrator with minimal tracking requirements. The concept of an inflatable compound parabolic concentrator was developed, which required modifying the theoretical profile geometry. An analytical model was created to predict the efficiency of the system for different design parameter configurations. The model was used to develop a design and manufacturing process which was used to design and manufacture small-scale and full-scale prototypes. Experiments were designed to test the performance of the concentrators and the test results were used to determine a model accuracy of 11.4 1.3 % and 1.9±1.6% using the small-scale prototype and full-scale prototype, respectively.

Abstract:

This thesis examines the prediction of concentrator photovoltaic system performance, and a model is presented where estimates are made using basic, fundamental material and atmospheric parameters, and successfully validated against measurements from a deployed system, to within 2% accuracy. A method to characterise the impact of individual atmospheric parameters on concentrator photovoltaic system performance is detailed and results are presented for potential deployment locations around the globe, demonstrating substantial differences in energy yield prediction accuracy if insufficient information is available, with up to 75% relative difference in energy yield and levelised cost of energy between basic and detailed simulations. In addition, the competitiveness of concentrator photovoltaic systems in different locations are benchmarked against existing technologies, showing significant geographical variation in their financial viability. The material quality in single and multijunction solar cells and its effect on the selection of optimal solar cell designs is investigated and the radiative efficiency of a device is proposed as a figure of merit to evaluate material quality. The optimal band gaps are shown to vary substantially depending on material quality at low solar concentrations, by hundred of milli-electron-volts, with ramifications for future solar cell designs. The impact of photon management, through radiative coupling, on cell performance is quantified for current and future high efficiency multijunction solar cell structures. Up to 5% enhancement due to radiative coupling can be expected for quad-junction solar cells, but current designs can expect below 1% enhancement. The work covered in this thesis has investigated and highlighted the potential problems associated with not fully understanding the atmospheric conditions in which concentrator photovoltaic systems operate, providing evidence and impetus for additional ground measurements or a drastic improvement in satellite-based measurement of atmospheric conditions. By integrating atmospheric parameters into an existing concentrator photovoltaic system modelling tool, new methods to characterise these conditions has been developed rigorously and accurately simulate system behaviour, a valuable resource to the field. In the design of optimal band gaps for multijunction solar cells, the work in this thesis shows that the material quality must be carefully considered in any design. A novel method has been developed to quantify material quality and provide a benchmark of state-of-the-art achieved values. The role of photon management in the form of radiative coupling is quantified, through the first examination of enhancement due to the effect, under realistic atmospheric conditions. This gives cell designers realistic expectations for performance enhancement.

Abstract:

Malaysia is one of the countries that have started to elevate the usage of renewable - specifically solar photovoltaic (PV) - in delivering its energy needs. This thesis is divided into two main sections. The first section evaluates the solar PV installations in the residential sector in Malaysia for the past 20 years; in terms of policies, research and development activities and implementations. Recently, the Feed-in Tariff (FiT) scheme was introduced in Malaysia and based on the financial analysis, any installation of solar PV could generate a lucrative monthly income to the household owner under the FiT scheme. However, a preliminary survey indicated that Malaysians are not interested in investing in a solar PV system, mainly due to the high cost of implementation. The next section focuses on the design of solar concentrators - particularly the family of Dielectric Totally Internally Reflecting Concentrators (DTIRCs) - with the aim of achieving a low cost solar PV system. Part of the PhD project is the optimisation of the concentrator design in the Solar Photonic Optoelectronic Transformer (SPOT), the main component of SolarBrane, a static building integrated PV (BlPV) system developed by SolarEmpower Ltd. An optimised design has been proposed using a DTIRC based on the Maximum Concentration Method (MCM). It has been demonstrated via simulations that the optimised design could potentially increase the output of the SolarBrane, at the cost of having a slightly larger structure. A novel type of DTIRC family. known as the Asymmetrical DTIRC (ADTIRC). has been developed to provide additional gain at the "extrusion" plane of the concentrator, and further reducing the size of the PV cell needed. It is concluded tbat this new design generates a much higher gain compared to the concentrator in the SolarBranel. The results from the indoor experiments indicate that the ADTIRC-PV structure could increase the electrical output by 4.2x when compared with the non-concentrating solar PV cell.

Brazil has as a main source for production of electricity the dams using water to drive the turbines and as a secondary source are used the thermoelectric power plants that use fuel oil for electric power production. Both generate a large environmental impact, due to the fact of the dams need huge areas for its construction, which often leads to destruction of important ecosystems in the region where it will be installed the hydroelectric plant, besides the fact that they need the rainfall cycle so that the dams have the operating capacity, while the thermoelectric power plants burn fossil fuels thus increasing emissions of CO2 to the atmosphere. An alternative to the solution of the problems mentioned above is the use of renewable sources of energy, with emphasis on this work. Solar energy can be divided into two parts: thermal and photovoltaic. This work it is focused on thermal use of solar energy, with a Fresnel-type solar concentrator to heat water, which will trigger a cooling system environment with the use of desiccant rotors. The choice of type Fresnel collector gave the field of development of this hub is still in constant growth and by the fact that even occupy a relatively small area when compared to other solar thermal concentrators, in addition to its construction be simple and low cost when again compared to other solar concentrators.
O Brasil tem como fonte principal para produção de energia elétrica as hidrelétricas que utilizam água para movimentar as turbinas e como fonte complementar são utilizadas as termoelétricas que usam óleo combustível para produção de energia elétrica. Ambas geram um grande impacto ambiental, devido ao fato das hidrelétricas necessitarem de enormes áreas para a construção das represas, o que muitas vezes acarreta na destruição de ecossistemas importantes para a região onde irá ser instalada a hidrelétrica, além do fato que elas necessitam do ciclo das chuvas para que as represas possuam capacidade de operação, enquanto que as termoelétricas queimam combustíveis fosseis, aumentando assim as emissões de CO2 para a atmosfera. Uma alternativa para a solução dos problemas citados anteriormente é a utilização de fontes renováveis de energia, dando ênfase neste trabalho a energia solar. A energia solar pode ser dividida em duas vertentes: térmica e fotovoltaica. Este trabalho está voltado para a utilização térmica da energia solar, através da utilização de um concentrador solar do tipo Fresnel para o aquecimento de água, a qual irá acionar um sistema de refrigeração de ambientes com a utilização de rotores dessecantes. A escolha do coletor do tipo Fresnel se deu pelo campo de desenvolvimento deste concentrador estar ainda em constante crescimento e pelo fato do mesmo ocupar uma área relativamente pequena quando comparado com outros concentradores solares térmicos, além de sua construção ser simples e de baixo custo quando novamente comparada a outros concentradores solares.

Abstract:

Solar concentrating systems are often used to decrease the cost of solar energy by redirecting the incident sunlight from a relatively large area onto a photovoltaic cell of smaller area. In addition to the convergence characteristics of the concentrator, indices of refraction and reflectivities which are functions of wavelength can result in an illumination which varies both spatially and spectrally on the solar cell. Nonuniformity can also be induced by concentrator tracking error. The effects of such nonuniform illumination on solar cell performance are of interest.In this investigation, a model of a concentrator solar cell consisting of a network of preexisting one-dimensional models has been developed. This model is analyzed for three sample grid configurations for both spot-focusing and line-focusing concentrator applications.Ada computer programs have been created which, together with a few other pieces of readily available software, are capable of simulating the model. Sample simulations have been performed for line-focusing concentrator applications. These results are presented and discussed.

Abstract:

The application of high speed computers to simulate physical devices has pioneered many scientific advances in recent times. With a suitable model to simulate their activity, solar cells are excellent candidates for such applications. In this work, a computer program has been developed which models an N+-P-P+ solar cell in one dimension. This model is structured to allow solar cells of different materials to be used in the program, however, only silicon is used here in order to demonstrate the capabilities of the program.For purposes of simplicity, the following conditions are assumed. All solar radiation enters the cell at normal incidence. The cell's temperature is uniform throughout and is considered a constant in all calculations. Doping concentrations in individual cell regions are uniform. Generation and recombination rates are also uniform within each of the cell's three regions. Items common to the two-dimensional cell but superficial to the one-dimensional cell such as contacts, lateral current flow, edge effects and variations of any type in the lateral direction are assumed to be non-existent.Background information for those not familiar with the topic is given followed by a presentation of the equations used. The general method of numerical calculation is then explained. Examples of program output are discussed along with an example application of the program. An entire program listing is given in appendix B.

Abstract:

Luminescent Solar Concentrators (LSCs) are an emerging technology that aims primarily to reduce the cost of photovoltaic (PV) power generation, with great potential for building-integrated photovoltaics (BIPV) system. Commercial realization of these devices is mainly hampered by reabsorption loss. This work describes a novel method of reducing the reabsorption as well as improving the directional emission utilizing stimulated emission, rather than only spontaneous emission as in standard LSCs, by using a seed laser. Light from a seed laser (potentially an inexpensive laser diode) passes through the entire area of the LSC panel, modifying the emission spectrum of the photoexcited luminophores such that it is spectrally narrower, at a wavelength that minimizes reabsorption and allows a net gain in the system, and is directed towards a small PV cell, anticipated to be ~ 1 mm2. A fraction of the PV cell’s output power is fed back to the seed laser; i.e. the system acts as a closed loop system. This thesis reports the design and working principle of a stimulated-LSC (s-LSC) and the development of a mathematical model to identify important physical parameters for the practical realization. Also, a novel method to characterize the luminophores for the s-LSC system is developed using a parameter called ‘stimulated gain coefficient.' Finally, this concept has been explored with the known photostable Perylene Red (PR) dyes for the proof of principle. The experimental results are well-matched with the model except for the gain saturation with a comparatively small seed laser signal power. To investigate this gain saturation, two approaches were taken: investigating (i) spectral hole burning and (ii) triplet state absorption. None of the existing luminophores investigated show the required characteristics for the s-LSC system. However, there is a plenty of room for the innovation of luminophores to realize a practical s-LSC system.

Abstract:

Luminescent solar concentrators are devices capable of converting some spectral components of solar radiation by luminescence and concentrating them before collection by photovoltaic. The aim of this thesis is to design, develop and demonstrate the principle of all-inorganic semitransparent luminescent solar concentrator (LSC) structures capable of passing most of the visible light through to provide illumination, while reflecting more than 90% of the UV and IR radiations and scattering them to the edges of the glass where they are collected by PV cells to produce electricity. All-inorganic visibly-transparent energy-harvesting clear laminated glass windows are the most practical solution to boosting building-integrated photovoltaics (BIPV) energy outputs significantly while reducing cooling- and heatingrelated energy consumption in buildings. A typical semitransparent luminescent solar concentrator is based on the integration of micro-engineered optical structures, nano-materials and IR-selective thin-film coatings, to realise stable, long-lifetime and shatterproof clear glass panels. The ability of the proposed semitransparent luminescent solar concentrators to generate electricity addresses the future net-zero-energy building demand [1, 2], making them ideal candidates for future high-rise glass buildings. The developed semitransparent luminescent solar concentrators employ low-e thin films, which particularly, provide many benefits, including, (i) building overall aesthetic appearance, (ii) low glare and (iii) filtration of unwanted components of the incident sunlight thus increasing the energy saving rating of buildings. The low-e glass panes are typically used in a double glazing structure in order to protect the low-e film from environmental impacts and improve the insulation properties of the semitransparent luminescent solar concentrators in addition to reducing the energy consumed for cooling or heating the inside of buildings. Multi-layer thin film coatings for solar and thermal radiation control are designed, using the Optilayer software package, developed using Physical Vapour Deposition (PVD), and tested using spectrophotometry. Experimental results show that the measured transmittance spectra for the developed structures are in agreement with simulation results and demonstrate that with the use of optimum metal-dielectric layer combination it is possible to transmit/reflect arbitrary spectral components of the incident sunlight. In addition, two types of semitransparent luminescent solar concentrator structures are designed, developed and characterised, namely: 1. LSCs incorporating inorganic luminophore materials into the lamination interlayer. These luminophores, when used in conjunction with spectrally-selective low-e thin-film coatings and CuInSe2 solar cells, enable most of the visible solar radiation to be transmitted through the glass window with minimum attenuation and the ultraviolet (UV) radiation to be down-converted and routed together with a significant part of infrared radiation to the edges for collection by solar cells. 2. Advanced LSCs incorporating inorganic luminophore materials as well as spectrallyselective diffraction gratings as light deflector structures of high visible transparency into the lamination interlayer. For these LSCs, most of the visible solar radiation can be transmitted through the glass windows with minimum attenuation while the ultraviolet (UV) and a part of incident solar infrared (IR) radiation energy are converted and/or deflected geometrically for routing towards the vicinity of glass panel edge regions for collection by solar cells. To boost the solar concentration capability of the laminated glass panes, functionalized epoxy interlayers are especially developed, which comprise UV-curable epoxy and inorganic luminophores with engineered absorption and emission bands. The developed functionalized interlayers demonstrate an excellent ability to scatter and concentrate sunlight within the glass structure with minimum reabsorption. Several materials and combinations of several luminophore types were investigated in order to determine the optimum interlayer structure that exhibits maximum UV and IR radiation scattering, conversion, and deflection towards the edge solar cells. Measured conversion efficiencies of 3.8% and 5.4% are achieved for 10 cm × 10cm LSCs samples without and with diffraction gratings, which correspond to output electrical power densities of 38Wp/m2 and 54 Wp/m2,respectively. A photobioreactor based on the developed semitransparent luminescent solar concentrator technology is developed, in collaboration with Murdoch University, for microalgae growth. An Insulated Glass Units (IGU) employing a special low-e thin film is developed, which passes more than 50% of the visible light while blocking more than 90% of the UV and IR radiations, hence, reducing the temperature inside the photobioreactor and improving the microalgae growth. The growth and productivity of the microalgae in the Insulated Glass

Abstract:

This thesis discusses aspects of a novel solar concentrating photovoltaic / thermal (PV/T) collector that has been designed to produce both electricity and hot water. The motivation for the development of the Combined Heat and Power Solar (CHAPS) collector is twofold: in the short term, to produce photovoltaic power and solar hot water at a cost which is competitive with other renewable energy technologies, and in the longer term, at a cost which is lower than possible with current technologies. To the authors knowledge, the CHAPS collector is the first PV/T system using a reflective linear concentrator with a concentration ratio in the range 20-40x. The work contained in this thesis is a thorough study of all facets of the CHAPS collector, through a combination of theoretical and experimental investigation. A theoretical discussion of the concept of energy value is presented, with the aim of developing methodologies that could be used in optimisation studies to compare the value of electrical and thermal energy. Three approaches are discussed; thermodynamic methods, using second law concepts of energy usefulness; economic valuation of the hot water and electricity through levelised energy costs; and environmental valuation, based on the greenhouse gas emissions associated with the generation of hot water and electricity. It is proposed that the value of electrical energy and thermal energy is best compared using a simple ratio. Experimental measurement of the thermal and electrical efficiency of a CHAPS receiver was carried out for a range of operating temperatures and fluid flow rates. The effectiveness of internal fins incorporated to augment heat transfer was examined. The glass surface temperature was measured using an infrared camera, to assist in the calculation of thermal losses, and to help determine the extent of radiation absorbed in the cover materials. FEA analysis, using the software package Strand7, examines the conductive heat transfer within the receiver body to obtain a temperature profile under operating conditions. Electrical efficiency is not only affected by temperature, but by non-uniformities in the radiation flux profile. Highly non-uniform illumination across the cells was found to reduce the efficiency by about 10% relative. The radiation flux profile longitudinal to the receivers was measured by a custom-built flux scanning device. The results show significant fluctuations in the flux profile and, at worst, the minimum flux intensity is as much as 27% lower than the median. A single cell with low flux intensity limits the current and performance of all cells in series, causing a significant drop in overall output. Therefore, a detailed understanding of the causes of flux non-uniformities is essential for the design of a single-axis tracking PV trough concentrator. Simulation of the flux profile was carried out using the ray tracing software Opticad, and good agreement was achieved between the simulated and measured results. The ray tracing allows the effect of the receiver supports, the gap between mirrors and the mirror shape imperfections to be examined individually. A detailed analytical model simulating the CHAPS collector was developed in the TRNSYS simulation environment. The accuracy of the new component was tested against measured data, with acceptable results. A system model was created to demonstrate how sub components of the collector, such as the insulation thickness and the conductivity of the tape bonding the cells to the receiver, can be examined as part of a long term simulation.
