Abstract:

This paper describes the results of research into multi-port converter design and control, specifically a pair of three-port topologies based on the half-bridge and full-bridge topologies. These converters are capable of simultaneous and independent regulation of two out of their three ports, while the third port provides the power balance in the system. A dynamic model was developed for each topology to aid in testing and for designing the control loops. The models were then used to design the control structures, and the results were tested in Simulink. In addition, a basic outline of a syste

Abstract:

The increasing demand of renewable energy is the big driving force for the research and development of more efficient solar energy conversion solutions. Solar cells, which use the photovoltaic effect to convert the photon energy to electrical current, are an important solar energy conversion technique. One solar cell technology is thin-film solar cells. Thin-film solar cells use an absorption layer with a direct band gap. A direct band gap has the advantage that the photons will penetrate less deep until a photoexcitation occur compared to semiconductors with an indirect band gap (e.g. silicon

Abstract:

Polycrystalline CdS/CdTe thin film solar cells are among the leading candidates for low-cost, large scale terrestrial photovoltaic applications. CdTe has a high absorption coefficient and it can absorb the radiant energy within less than 2 µm of thickness. This makes it suitable for thin film applications. CdTe has a band gap of 1.45 eV at room temperature, which is nearly optimum for photovoltaic conversion efficiency under the AM 1.5 solar spectrum. The theoretical maximum efficiency for CdTe solar cells is 29%. However, to-date the experimental value is in the 16 % range. In most cases CdTe

Abstract:

In polycrystalline silicon (pc-Si) thin-film solar cells, defect passivation is critical to device performance. Isoelectronic or covalently bonded impurities, hydrogenic, extended defects and defects with localized levels in the bandgap (deep level defects) are typically introduced during the fabrication of, and/or are inherent to, pc-Si thin-film solar cells. These defects dramatically affect minority carrier lifetimes. Removing and/or passivating these defects is required to maximize minority carrier lifetimes and is typically done through thermal annealing and passivation techniques. For pc

碩士<br>國立成功大學<br>電機工程學系<br>105<br>SUMMARY CZTSSe is a promising material for thin film solar cells, which consists of earth-abundant, low-cost and environmentally friendly material compared to CIGS or CdTe. CZTSe thin films were fabricated using DMSO-based spin coating technique. In this work, we investigate the effects of potassium-doping concentration on the selenized CZTSSe thin film. EDS and SEM were performed to analyze the change of composition and morphology of films. XRD and Raman were used to confirm the crystal structure of CZTSSe thin film. CZTSSe-based device was measured through I-

碩士<br>崑山科技大學<br>機械工程研究所<br>97<br>This thesis uses sulfurization method to form the CuIn(Se,S)2 film. Firstly, the RF sputtering system is used to pre-deposit a CuInSe2 layer. Secondly, the sulfurization method is applied to make the CuInSe2 layer become CuIn(Se,S)2 film. The sulfurization is the only process under the atmosphere pressure, all the rest processes are located in a low vacuum environment and the PVD (Physical Vapor Deposition) method is applied to coat the film. The purpose of using sulfurization method to form the CuIn(Se,S)2 film is to solve the problem of Se loss. The pre-depo

We have doped TiO2 nanoparticles to improve the performance of polymer solar cells based on P3HT:PCBM. The morphology of polymer solar cell was improved due to the additional of TiO2 nanoparticles.

The post-etching succeeded to reduce dark current and series resistance with increasing open circuit voltage (Voc), fill factor (FF), and efficiencies (EFF) for GaAs solar cell. We found the low specific resistance (~10-7Ω㎝2) of PdGeTiPt by using Transmission-Line Method (TLM) and realize with InGaP solar cells that can reduce the series resistance. Finally, we attempted to change the different spacing of solar cells’ grid fin

However, at the present stage, most studies on SWHS focus on household SWHS. Public SWHSs are relatively complicated and thus with very few studies. This study aimed at assessing cost-effectiveness of practical usage for four SWHSs self-designed and constructed by Army Post (AP). The results indicate only Taichung AP acquires cost-effectiveness of practical usage. The hot-water supply in Kaohsiung AP is

However, the performance of organic solar cells is not good enough for the mass production. This research aims at improving the short-circuit current density of organic solar cells, and hence improving the conversion efficiency of cells.
