英文摘要：

This review presents recent developments on CuInGaSe_2（CIGS） thin film solar cells and the key solar materials（such as surface-textured ZnO：Al transparent conducting films,graphene,and anti-reflection SiO_2 coatings）.A route to fabricate CIGS solar cells,which belongs to a non-vacuum low-cost method for producing CIGS solar cells,is proposed.The photovoltaic efficiency of the solar cell can be 13.83%.The fabrication of high performance key materials is the main route to reduce the cost and improve the efficiency of the solar cells which can realize the stable enhancement of the properties and the sustainable development of the photovoltaic cells.
