Abstract:

Thin-film silicon photovoltaics are seen as a good possibility for reducing the cost of solar electricity. The focus of this thesis is the ALICIA cell, a thin-film polycrystalline silicon solar cell made on a glass superstrate. The name ALICIA comes from the fabrication steps - ALuminium Induced Crystallisation, Ion Assisted deposition. The concept is to form a high-quality crystalline silicon layer on glass by Aluminium Induced Crystallisation (AIC). This is then the template from which to epitaxially grow the solar cell structure by Ion Assisted Deposition (IAD). IAD allows high-rate si

Abstract:

Dielectric thin films have a long history in silicon photovoltaics. Due to the specific physical properties, they can function as passivation layer in solar cells. Also, they can be used as antireflection coating layers on top of the devices. They can improve the back surface reflectance if proper dielectric layers combination is used. What??s more, they can protect areas by masking during chemical etching, diffusion, metallization among the whole fabrication process. Crystalline silicon solar cell can be passivated by two ways: one is to deposit dielectric thin films to saturate the dangling

Abstract:

Thin-film silicon solar cells have the potential to convert sunlight into electricity at high efficiency, low cost and without generating pollutants. However, they need to become more competitive with conventional energy technologies by increasing their efficiency. One of the key efficiency limitations of using thin silicon absorber materials relates to the optical loss of low-energy photons, because the absorption coefficient of silicon decreases strongly for these low-energy photons in the red and near-infrared, such that the absorption length becomes longer than the absorber layer thickness

Abstract:

Cu₂S/CdS solar cells have been studied extensively for the past two decades due to their potentially high efficiencies per unit cost. The operation and characteristics of Cu₂S/CdS solar cells are fairly well understood. However, the properties of the newer Cu₂S/ZnCdS cell type are not well understood. The main goals of this thesis were to compare Cu₂S/CdS and Cu₂S/ZnCdS cells using Cu₂S/CdS cells as a reference, and to understand the operation and properties of Cu₂S/ZnCdS cells in order to improve cell performance. Four different measurements were used in this research to achieve these goals.

Microcrystalline silicon solar cells require an enhanced absorption of photons in the near-bandgap region between 700-1150nm. Conventional textured mirrors scatter light and increase the path length of photons in the absorber by total internal reflection. However, these mirrors exhibit a high surface roughness which degrades the performance of the microcrystalline silicon device. An alternative solution is to use metal nanoparticles with low surface roughness to scatter light. An illuminated metal nanoparticle exhibits a resonant or plasmonic excitation which can be tuned to enable a strong sc

碩士<br>國立臺北科技大學<br>材料科學與工程研究所<br>99<br>The Cu2O thin films were prepared on Corning Eagle 2000 glass substrate by reactive direct current magnetron sputtering. The influences of oxygen flow rate, argon flow rate and annealing temperature on the structures and properties of deposited films were investigated. Mixtures of Cu, Cu2O, Cu4O3 and CuO with different optical and electrical properties were found to form under different process conditions. Cu2O thin films that are suitable for absorption layer in solar cell can be obtained by reactive magnetron sputtering at 200 °C under 1.65 × 10-2 Torr o

碩士<br>國立雲林科技大學<br>電子工程系<br>102<br>The indium and gallium of CIGS are rare materials in the earth, and the hydrogen selenide (H2Se) is a toxic gas in selenization process. In recent years, some alternative absorbent materials have been developed for the thin film solar cells, such as Cu2ZnSnS4 (CZTS), Cu2ZnSnSe4 (CZTSe), and other similar quaternary compounds of chalcopyrite structures. In this work, copper zinc tin sulfide (Cu2ZnSnS4) films were investigated as the absorbent layer for the thin film solar cells. The CZTS film is of p-type direct bandgap semiconductor and is suitable as the abso

碩士<br>國立臺灣科技大學<br>光電工程研究所<br>102<br>In this work, GaN surface roughening techniques were developed and used in solar cells to increase the photocurrent density. Typical commercial GaN LED wafers that we used to fabricate GaN solar cells have very thin active layers resulting in quite low solar light absorption. Therefore we added a surface scattering layer by surface roughening to increase the optical length of the incident light in the active layer in order to increase light absorption and photocurrent density. In this work, SiO2 sub-micron spheres of approximately 300 nm in diameter were use
