Solar cells based on CuInS2 an overview

Over the recent years CuInS2 has emerged as a promising absorber material for thin film photovoltaic modules. A pilot production line for full size 120 x 60 ?cm 2 modules is currently being established. CuInS 2 preparation, material properties, and cell structure are in many aspects comparable to those of the more widely researched selenium containing chalcopyrite absorbers but there are also unique features of this material. In this contribution we give an overview of the historical development, current status, and near to mid term future of CuInS 2 based device
