Abstract

Although CIGS solar cells consist of a polycrystalline thin film grown on a glass substrate, more than 20% conversion efficiency has been achieved. The efficiency has reached the same level as polycrystalline silicon solar cells. This high efficiency has not yet been observed in other thin film solar cells including thin film Si and CdTe. Therefore, it is important to understand the mechanisms that allow CIGS solar cells to exhibit high conversion efficiencies. This paper discusses the origin of the high efficiency and demonstrates that it is caused by the unique material properties of CIGS films.
