Abstract:
Photovoltaic cells have recently attracted considerable attention for indoor energy harvesting for low-power-consumption electronic products due to the rapid growth of the Internet of Things (IoT). The IoT platform is being developed with a vision of connecting a variety of wireless electronic devices, such as sensors, household products, and personal data storage devices, which will be able to sense and communicate with their internal states or the external environment. A self-sustainable power source is required to power such devices under low light indoor environments. Inorganic photovoltaic cells show excellent device performance under 1 Sun illumination and dominate the market for outdoor applications. However, their performance is limited for indoor applications with low incident light intensities as they exhibit low photo-voltage. Among the emerging photovoltaic technologies, organic photovoltaics have unique advantages, including solution processibility, flexibility, and lightweight tailorable design; hence, they are considered the best solution for indoor light harvesting applications due to their high photo-voltage, strong absorption of UV-visible wavelengths, and a spectral response similar to that emitted by modern indoor lighting systems. In this review article, we discuss the factors affecting device performance of different photovoltaic technologies under low incident light intensities or indoor conditions and provide a comprehensive analysis of future opportunities for enhancing indoor performance of the photovoltaic devices. Furthermore, we discuss some of the results of semi-transparent organic solar cell which operated under complex environmental conditions like low illumination, incident light angle etc. Based on the results, one can suggest that semi-transparent organic solar cell is a more suitable case for progressive indoor solar cell. After highlighting the factors that limit indoor device performance of photovoltaic cells, we discuss potential applications of IoT devices powered by organic photovoltaic cells in indoor lighting environments.

AbstractWe consider the fundamental limits to organic solar cell efficiency, and the schemes that have been used to overcome many of these limitations. In particular, the use of double and bulk heterojunctions, as well as tandem cells employing materials with high exciton diffusion lengths, is discussed.We show that in the last few years, a combination of strategies has led to a power conversion efficiency of ηp = 5.7% (under AM 1.5 G simulated solar radiation at 1 sun intensity) for tandem cells based on small-molecularweight materials, suggesting that even higher efficiencies are possible.We conclude by considering the ultimate power conversion efficiency that is expected from organic thinfilm solar cells.

Abstract:
It is necessary to develop semitransparent photovoltaic cell for increasing the energy density from sunlight, useful for harvesting solar energy through the windows and roofs of buildings and vehicles. Current semitransparent photovoltaics are mostly based on Si, but it is difficult to adjust the color transmitted through Si cells intrinsically for enhancing the visual comfort for human. Recent intensive studies on translucent polymer- and perovskite-based photovoltaic cells offer considerable opportunities to escape from Si-oriented photovoltaics because their electrical and optical properties can be easily controlled by adjusting the material composition. Here, we review recent progress in materials fabrication, design of cell structure, and device engineering/characterization for high-performance/semitransparent organic and perovskite solar cells, and discuss major problems to overcome for commercialization of these solar cells.

Abstract:
The photovoltaic conversion efficiency of solar cells is highly temperature dependent and decreases with increasing temperature. Therefore, the thermal management of solar cells is crucial for the efficient utilization of solar energy. We fabricate a hybrid photovoltaic/thermocell (PV/T) module by integrating a thermocell directly into the back of a solar panel and explore the feasibility of the module for its practical implementation. The proposed PV/T hybrid not only performs the cooling of the solar cells but also produces an additional power output by converting the heat stored in the solar cell into useful electric energy through the thermocell. Under illumination with an air mass of 1.5 G, the conversion efficiency of the solar cell can improve from 13.2% to 15% by cooling the solar cell from 61 °C to 34 °C and simultaneously obtaining an additional power of 3.53 μW/cm2 from the thermocell. The advantages of the PV/T module presented in this work, such as the additional power generation from the thermocell as well as the simultaneous cooling of the solar cells and its convenient installation, can lead to the module’s importance in practical and large-scale deployment.

Abstract:

This project is an extension of a pre-existing simulation program (‘Simulation_2dioden’). This simulation program was first developed in Konarka Technologies. The main purpose of the project ‘Simulation_2dioden’ is to calibrate the values of different parameters like, Shunt resistance, Series resistance, Ideality factor, Diode current, epsilon, tau, contact probability, AbsCT, intensity, etc; This is one of the curve fitting procedure’s. This calibration is done by using different equations. Diode equation is one of the main equation’s used in calculating different currents and voltages, from the values generated by diode equation all the other parameters are calculated.

The reason for designing this simulation_2dioden is to calculate the values of different parameters of a device and the researcher would know which parameter effects more in the device efficiency, accordingly they change the composition of the materials used in the device to acquire a better efficiency. The platform used to design this project is ‘Microsoft Excel’, and the tool used to design the program is ‘Visual basics’. The program could be otherwise called as a ‘Virtual Solar cell’. The whole Virtual Solar cell is programmed in a single excel sheet.

An Automated working solution is suggested which could save a lot of time for the researchers, which is the main aim of this project. To calibrate the parameter values, one has to load the J-V characteristics and simulate the program by just clicking one button. And the parameters extracted by using this automated simulation are Parallel resistance, Series resistance, Diode ideality, Saturation current, Contact properties, and Charge carrier mobility.

Finally, a basic working solution has been initiated by automating the simulation program for calibrating the parameter values.

Abstract:
This thesis outlines investigations of metal oxide/organic interfaces in photo-voltaic devices. It focuses on device instabilities originating from the metal oxide layer surface sensitivity and it presents suggested mechanisms behind these in- stabilities. A simple sol-gel solution deposition technique for the fabrication of stable and highly performing transparent conducting mixed metal oxides (ZnMO) is presented. It is demonstrated that the use of amorphous, mixed metal oxides allows improving the performance and stability of interfacial charge extraction layers for organic solar cells. Two novel ternary metal oxides, zinc-strontrium- oxide (ZnSrO) and zinc-barium-oxide (ZnBaO), were fabricated and their use as electron extraction layers in inverted organic photovoltaics is investigated. We show that using these ternary oxides can lead to superior devices by: prevent- ing a dipole forming between the oxide and the active organic layer in a model ZnMO/P3HT:PCBM OPV as well as lead to improved surface coverage by a self assembled monolayer and promote a significantly improved charge separation efficiency in a ZnMO/P3HT hybrid device. Additionally a spectroscopic technique allowing a versatility of characterisa- tion for long-term stability investigations of organic solar cells is reported. A device instability under broadband light exposure in vacuum conditions for an inverted ZnSrO/PTB7:PC71BM OPV is observed. Direct spectroscopic evidence and electrical characterisation indicate the formation of the PC71BM radical an- ion associated with a loss in device performance. A charge transfer mechanism between a heavily doped oxide layer and the organic layers is suggested and dis- cussed.

Abstract:
Organic solar cells have the potential to be portable power sources that are light-weight, flexible, and inexpensive. However, the highest power conversion efficiency for organic solar cells to date is ~8%, and most high-efficiency solar cells have an area of less than 1 cm². This thesis advances the field of organic solar cells by studying the physics and engineering of the devices to understand the reverse saturation current, which is related to efficiency, and the effects of area scaling. The most commonly accepted models to describe the physics of organic photovoltaic devices are reviewed and applied to planar heterojunction solar cells based on pentacene / C60 as a model system. The equivalent circuit model developed for inorganic solar cells is shown to work well to describe the behavior of organic devices and parameterize their current-voltage characteristics with five parameters. Changes in the parameters with different material combinations or device structures are analyzed to better understand the operation of the presented organic solar cells. A one-dimensional diffusion model for the behavior of excitons and treatment of the organic layers as planes is demonstrated to adequately model the external quantum efficiency and photocurrent in pentacene / C60 solar cells. The origin of the open-circuit voltage is studied using cells with different electrodes and different donor materials. While changing the electrodes does not affect open-circuit voltage, it is greatly modified by changes in the donor. Tests with additional semiconductors show the change in open-circuit voltage is not consistent from donor to donor as the acceptor is varied, suggesting a more complex relation than just the difference in energy levels. Study of the temperature dependence of the equivalent circuit parameters shows that the reverse saturation current, which has a significant role in determining the open-circuit voltage, has a thermally activated behavior. From this behavior, the reverse saturation current is related back to charge transfer at the donor / acceptor heterojunction to suggest that both the effective energy barrier presented by the energy levels and the electronic coupling are important in determining the reverse saturation current and open-circuit voltage. This marks a shift from just considering a built-in voltage or the energy levels to also considering the electronic coupling of the donor and acceptor materials. Temperature-dependent performance characteristics are also used to show key differences between organic and inorganic devices. Finally, the effect of area scaling is explored with pentacene / C60 solar cells having areas of 0.11, 7, and 36.4 cm². Analysis with the equivalent circuit model shows that performance decreases as area increases because of an increasing series resistance presented by the transparent electrode. A metal grid, to provide low resistance pathways for current, fabricated on top of the transparent electrode is proposed to reduce the effective resistance. The grid is unique in that it is placed between the electrode and the semiconductor layer and must be passivated to prevent shorts through the thin semiconductor to the back metal electrode. Analysis of the grid predicts greatly reduced series resistance, and experimental results show reduced resistance and improved performance for the 7 cm² and 36.4 cm² devices when including the grid.

Abstract:
Active layer morphology of polymer-based solar cells plays an important role in improving power conversion efficiency (PCE). In this thesis, the focus is to improve the device efficiency of polymer-based solar cells. In the first objective, active layer morphology of polymer-solar cells was optimized though a novel solvent annealing technique. The second objective was to explore the possibility of replacing the highly sensitive aluminum cathode layer with a low-cost and stable alternative, copper metal. Large scale manufacturing of these solar cells is also explored using roll-to-roll printing techniques. Poly (3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl (PCBM) were used as the active layer blend for fabricating the solar cell devices using bulk heterojunction (BHJ), which is a blend of a donor polymer and an acceptor material. Blends of the donor polymer, P3HT and acceptor, PCBM were cast using spin coating and the resulting active layers were solvent annealed with dichlorobenzene in an inert atmosphere. Solvent annealed devices showed improved morphology with nano-phase segregation revealed by atomic force microscopy (AFM) analysis. The roughness of the active layer was found to be 6.5 nm. The nano-phase segregation was attributed to PCBM clusters and P3HT domains being arranged under the solvent annealing conditions. These test devices showed PCE up to 9.2 % with current density of 32.32 mA/cm2, which is the highest PCE reported to date for a P3HT-PCBM based system. Copper was deposited instead of the traditional aluminum for device fabrication. We were able to achieve similar PCEs with copper-based devices. Conductivity measurements were done on thermally deposited copper films using the two-probe method. Further, for these two configurations, PCE and other photovoltaic parameters were compared. Finally, we studied new techniques of large scale fabrication such as ultrasonic spray coating, screen-printing, and intense pulse light sintering, using the facilities at the Conn Center for Renewable Energy Research at the University of Louisville. In this study, prototype devices were fabricated on flexible ITO coated plastics. Sintering greatly improved the conductivity of the copper nano-ink cathode layer. We will explore this technique’s application to large-scale fabrication of solar cell devices in the future work.

Abstract:
This work investigates organic solar cells made of small molecules. Using the material system α,ω-bis(dicyanovinylene)-sexithiophene (DCV6T) - C60 as model, the correlation between the photovoltaic active layer morphology and performance of the solar cell is studied. The chosen method for controlling the layer morphology is applying different substrate temperatures (Tsub ) during the deposition of the layer. In neat DCV6T layers, substrate heating induces higher crystallinity as is shown by X-ray diffraction and atomic force microscopy (AFM). The absorption spectrum displays a more distinct fine structure, a redshift of the absorption peaks by up to 11 nm and a significant increase of the low energy absorption band at Tsub = 120°C compared to Tsub = 30°C. Contrary to general expectations, the hole mobility as measured in field effect transistors and with the method of charge extraction by linearly increasing voltage (CELIV) does not increase in samples with higher crystallinity. In mixed layers, investigations by AFM and UV-Vis spectroscopy reveal a stronger phase separation induced by substrate heating, leading to larger domains of DCV6T. This is indicated by an increased grain size and roughness of the topography, the increase of the DCV6T luminescence signal, and the more distinct fine structure of the DCV6T related absorption. Based on the results of the morphology analysis, the effect of different substrate temperatures on the performance of solar cells with flat and mixed DCV6T - C60 heterojunctions is investigated. In flat heterojunction solar cells, a slight increase of the photocurrent by about 10% is observed upon substrate heating, attributed to the increase of DCV6T absorption. In mixed DCV6T : C60 heterojunction solar cells, much more pronounced enhancements are achieved. By varying the substrate temperature from -7°C to 120°C, it is shown that the stronger phase separation upon substrate heating facilitates the charge transport, leading to a significant increase of the internal quantum efficiency (IQE), photocurrent, and fill factor. Consequently, the power conversion efficiency (PCE) increases from 0.5% at Tsub = -7°C to about 3.0 % at Tsub ≥ 77°C. Subsequent optimization of the DCV6T : C60 mixing ratio and the stack design of the solar cell lead to devices with PCE of 4.9±0.2 %. Using optical simulations, the IQE of these devices is studied in more detail to identify major remaining loss mechanisms. The evaluation of the absorption pattern in the wavelength range from 300 to 750 nm shows that only 77 % of the absorbed photons contribute to the exciton generation in photovoltaic active layers, while the rest is lost in passive layers. Furthermore, the IQE of the photovoltaic active layers, consisting of an intrinsic C60 layer and a mixed DCV6T : C60 layer, exhibits a lower exciton diffusion efficiency for C60 excitons compared to DCV6T excitons, attributed to exciton migration into the adjacent electron transport layer
Diese Arbeit befasst sich mit organischen Solarzellen aus kleinen Molekülen. Anhand des Materialsystems α,ω-bis(Dicyanovinylen)-Sexithiophen (DCV6T) - C60 wird der Zusammenhang zwischen Morphologie der photovoltaisch aktiven Schicht und dem Leistungverhalten der Solarzellen untersucht. Zur Beeinflussung der Morphologie werden verschiedene Substrattemperaturen (Tsub ) während des Schichtwachstums der aktiven Schicht eingestellt. Beim Heizen des Substrates weisen DCV6T Einzelschichten eine erhöhte Kristallinität auf, die mittels Röntgenbeugung und Rasterkraftmikroskopie (AFM) erkennbar ist. Zudem bewirkt die Erhöhung der Substrattemperatur von 30°C auf 120°C eine ausgeprägtere Feinstrukturierung des Absorptionsspektrums, eine Rotverschiebung um bis zu 11 nm und eine Verstärkung der niederenergetischen Absorptionsbande. Entgegen den Erwartungen wird weder in Feldeffekttransistoren noch mit der Methode der Ladungsextraktion bei linear steigenden Spannungspulsen (CELIV) eine Verbesserung der Löcherbeweglichkeit in Zusammenhang mit der erhöhten Kristallinität gemessen. Mischschichten mit C60 weisen bei erhöhten Substrattemperaturen eine stärkere Phasentrennung auf, die zu größeren DCV6T Domänen innerhalb der Schicht führt. Dieser Effekt wird zum Einen durch größere Körnung und Rauigkeit der Topographie, zum Anderen durch die Erhöhung des Lumineszenzsignals von DCV6T sowie der Ausprägung der Feinstruktur im Absorptionsspektrum nachgewiesen. Ausgehend von den Ergebnissen der Morphologieuntersuchung werden die Auswirkungen von verschiedenen Substrattemperaturen auf das Leistungsverhalten von DCV6T - C60 Solarzellen mit planarem und Volumen-Heteroübergang analysiert. Solarzellen mit planarem Heteroübergang weisen eine geringe Verbesserung des Photostromes von etwa 10 % beim Heizen des Substrates auf. Diese wird durch die Erhöhung der DCV6T Absorption verursacht. In Volumen-Heteroübergängen führt die stärkere Phasentrennung bei steigender Substrattemperatur im untersuchten Temperaturbereich von -7°C bis 120°C zu einer Verbesserung des Ladungsträgertransports. Dadurch verbessern sich die interne Quanteneffizienz (IQE), der Photostrom und der Füllfaktor. Der Wirkungsgrad der Solarzellen erhöht sich von 0.5 % bei Tsub = -7°C auf 3.0 % bei Tsub ≥ 77°C. Eine weitere Optimierung des DCV6T : C60 Mischverhältnisses und des Schichtaufbaus ermöglicht Solarzellen mit Wirkungsgraden von 4.9±0.2 %. Mittels optischer Simulationen wird die IQE dieser Solarzellen näher untersucht, um verbleibende Verlustmechanismen zu identifizieren. Es ergibt sich, dass innerhalb des Wellenlängenbereichs von 300 bis 750 nm nur 77 % der absorbierten Photonen tatsächlich in den photovoltaisch aktiven Schichten absorbiert werden, während der Rest in nicht aktiven Schichten verloren geht. Des Weiteren kann nachgewiesen werden, dass C60 Exzitonen aus der aktiven Schicht, bestehend as einer intrinsischen C60 Schicht und einer DCV6T : C60 Mischschicht, durch Diffusion in die angrenzende Elektronentransportschicht verloren gehen

Abstract:
Transferring organic photovoltaics (OPV) from the laboratory into economically feasible products, requires the fabrication of modules, a series of connected single cells. During this transition, there is typically a drastic decrease in power conversion efficiency (PCE). This thesis reports on the design, fabrication, and characterization of state-of-the-art, high-performance organic photovoltaic modules with a novel geometry that composed of unit cells with alternating electrical polarities. Such configuration is realized by exclusive patterning of the interlayers and electrodes and avoids patterning of the photoactive layer. With this novel architecture, area losses of photovoltaic module can be significantly reduced compared with the conventional configurations. The processing of this new solar cell module is also compatible with large area processing techniques such as slot-die coating. This thesis reports on 4-cell and 8-cell modules, wherein the measured fill-factors (FF) and PCE of the constituent sub-cells and of the modules are almost identical. The 4-cell module, with a total area of 0.8 cm2, exhibits an open-circuit voltage (VOC) of 3.15 V, a short circuit-current density (JSC) of 2.3 mA/cm2 and a FF of 0.69, yielding a PCE of 5.01%. The 8-cell module, with a total area of 1.6 cm2, exhibits a VOC of 6.39 V, a JSC of 1.2 mA/cm2 and a FF of 0.63, yielding a PCE of 5.06%. Similar PCE values between 4-cell and 8-cell module is a demonstration of scalability of this novel geometry without compromising the efficiency.

Les durées de vie des cellules solaires photovoltaïques organiques (OPV) doivent être améliorées afin que cette technologie puisse être commercialisée sur une grande échelle. Ce travail étudie l’influence de la sélection des matériaux pour l’interface supérieure sur la dégradation des OPV inversées. La première partie de cette étude s’occupe des effets de la dégradation thermale. Il a été constaté que la tension de circuit-ouvert (VOC) et le facteur de forme (FF) diminuent lors du vieillissement des OPVs ayant une HTL de MoO3 et une électrode d’argent. Des expériences de caractérisation physique ont mis en évidence que les électrodes d’argent démouillent lors du vieillissement thermique ce qui peut conduire à la mort rapide des cellules avec des électrodes minces. Des analyses de rupture ont également faites. Il a été constaté que l’adhésion d’interface supérieure augmente fortement dans les échantillons avec électrode en argent due à la diffusion de matière, et il est possible qu’il y ait une relation entre cette diffusion et la perte de VOC et FF. Dans la deuxième partie, les effets de la lumière sur la dégradation et l’influence de la présence d’oxygène ou d’humidité ont été étudiés. Quelques effets des matériaux ont été notés, en particulier sur la durée de vie. L’oxygène a eu l’effet d’accélérer notablement la dégradation, et aucune différence n’a été notée selon les matériaux utilisés. En revanche, l’humidité a eu un effet prononcé sur les échantillons avec certains HTLs. Ce travail souligne l’importance de penser à la durée de vie quand on désigne les dispositifs OPV, en particulier pour sélectionner des matériaux appropriés afin d’optimiser la durée de vie
Organic photovoltaic (OPV) solar cells show great promise but suffer from short operating lifetimes. This study examines the role that the selection of materials for the hole extraction interface in inverted OPV devices plays in determining the lifetime of a device. In the first part of the study, the effects of thermal degradation were examined. It was found that devices containing MoO3 HTLs and silver top electrodes exhibit an open-circuit voltage (VOC)/fill factor (FF)-driven mechanism. Physical characterisation experiments showed that, with heating, the silver electrode undergoes de-wetting. With thin electrodes this can result in the catastrophic failure of the device. A fracture analysis study found that silver-containing devices experience an increase in adhesion of their top layers to the active layer due to interdiffusion between the layers. This interdiffusion may be related to the loss of VOC and FF in Ag/MoO3 devices through diffused species forming charge traps in the active layer. In the second part of the study, the effects of photodegradation in different atmospheres were studied. Some material-dependent effects were observed when the devices were aged in an inert atmosphere, including variations in projected lifetime. The effect of oxygen was to greatly accelerate degradation, and remove any of the material-dependence observed in the inert experiment, while humidity led to a substantial increase in the degradation rate of devices containing PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate). This study underlines the importance of considering device lifetime in device design, and choosing materials to minimise degradation

Though relatively young, the field of organic electronics is a rapidly growing market and considerable research is being done in creating a whole range of devices from organic molecules from organic field effect transistors to LEDs to photovoltaic devices. The field of organic photovoltaic in particular has become important in recent years with the push for newer, renewable sources of energy to end the dependence on fossil fuels. While the efficiencies of organic photovoltaic devices continue to rise, one barrier to their commercial adoption has been the limited lifetimes of these devices. While certain degradation methods of organic photovoltaics, such as photo-oxidation, have been extensively studied and solutions to these problems, such as encapsulation, are being researched, certain other degradation mechanisms are less understood and studied. The focus of this thesis is on one such degradation mechanism, UV degradation, specific to the ITO-pentacene interface in pentacene/C60 organic photovoltaic devices. Attempts were made to increase the lifetime of the devices by using phosphonic acids or oxygen plasma to modify the surface of the ITO. While conducting these experiments, the lack of a system to test the lifetime of multiple devices for long periods of time became apparent. As such as system was a requirement for future research into the lifetimes of organic photovoltaic devices a system was designed and built. The system would operate the photovoltaic device in a way comparable to its end-use and would allow over 100 devices to be tested simultaneously for durations exceeding 10,000 hours if necessary. This system would allow for statistically significant lifetime testing to be carried out in the future.

Abstract:
The enhancement of the optical efficiency in both, organic and non-organics photovoltaic cells, with inclusion of metallic nanoparticles that induces surface plasmon resonant effects, is determined and studied by computational simulations. The Maxwell equations are solved in the frequency domain using a Finite Element Methods (FEM) based computational program. The absorption of the active layer is directly obtained and weighted by the corresponding solar spectrum. Then, the photovoltaic cell optical efficiency is ultimately determined. This investigation demonstrated that for photovoltaic cells without nanoparticles, there exist three optimal configurations: an organic glass/PEDOT:PSS/CuPc:PTCBI/Ag cell; and non-organic glass/ ITO/CuInSe2/Ag and glass//ITO/CdTe/Ag cells. The numerical simulations show that optimal efficiency depends on the cell material and positioning of the nanoparticle within the cell. For an organic cell, the optimal efficiency was obtained with silver nanoparticles positioned at the bottom of the active layer (position 3); whereas, for non-organic cells, the optical efficiency was obtained with aluminum nanoparticles positioned between the glass and TCO layers (position 1). From the three dimensional simulations, it was determined that silver nanoparticles with a diameter of 80nm within a cubic cell of period 230nm positioned in position 3 of the active layer of CuPc:PTCBI of an organic photovoltaic cell allow the augmentation of the efficiency such that a similar efficiency can be obtained with a cell of the same material but without nanoparticles and an active layer thickness 94% higher than with nanoparticles. For aluminum nanoparticles with a diameter of 30 nm in a cubic cell of period 40nm positioned in position 1 of the active layer de CuInSe2 of a non-organic photovoltaic cell, the efficiency is augmented to such a value that this value can be obtained with a non-organic photovoltaic cell with no nanoparticles and a an active layer thickness 137% higher than with nanoparticles.
