摘　　要：In this article, we discuss the leading thin-film photovoltaic （PV） technology based on the Cu（ln,Ga）Se2 （CIGS） compound semiconductor. This contribution includes a general comparison with the conventional Si-wafer-based PV technology and discusses the basics of the CIGS technology as well as advances in world-record-level conversion efficiency, production, applications, stability, and future developments with respect to a flexible product. Once in large-scale mass production, the CIGS technology has the highest potential of all PV technologies for cost-efficient clean energy generation.本文讨论了基于Cu(In,Ga)Se_2(CIGS)复合薄膜半导体材料的光伏(PV)技术。主要内容包括CIGS技术与传统的晶体硅技术的总体比较、CIGS技术基础、一种柔性CIGS电池产品破世界纪录的转化效率,以及在生产、应用和稳定性方面的突出表现和良好的发展前景。CIGS技术极具潜力,若能实现大规模量产,将成为所有光伏清洁发电技术中成本最低的一种技术。
