| Summary: | 碩士 === 國立臺灣大學 === 電子工程學研究所 === 103 === Modeling of photovoltaic devices has become more and more important and helpful not only to predict the performance of new devices but also to provide ideas and guidelines to industry without manufacture. This thesis focuses on discussing the optical and electrical characteristics of Cu(In,Ga)Se (CIGS) solar cells, as well as the cell-to-module current gain.
The CIGS solar cell is simulated in two-dimensional simulation. In chapter two, the electrical and optical simulation of the CIGS and Cu(In,Ga)(Se,S) (CIGSeS) is done. The influence of different gallium and sulfur mole fraction is reported. The CIGS and CIGSeS solar cell achieve a optimized efficiency.
The cell-to-module current gain is simulated in three-dimensional simulation. In chapter three, several kinds of module light loss are shown and as well as the current of conventional solar module. In chapter four, four improvements contain glass anti-reflective coating (ARC), front glass thickness (TG), polyvinyl butyral encapsulant (PVB), and light harvesting strings (LHS) are used to optimized the solar module. The individual and combined improvement is considered, to achieve a higher current gain of the solar module.
