摘要
Cu(In, Ga)Se-2 (CIGS) thin film was prepared by ion beam sputtering Cu, In, Se and evaporating Ga elements continuously on BK7 glass substrate and the 4-layer film was then annealed at 400 degrees C for 1h in the same vacuum chamber. The CIGS thin film is single-phase with chalcopyrite structure and has a preferential (112) orientation. Its elemental composition approaches the stochiometric composition ratio of 1:0.7:0.3:2 and it consists of densely packed grain clusters. An energy band gap of about 1.30 eV and an absorption coefficient of 10(5) cm(-1) are obtained. Thus, an optimization of the fabrication for CIGS thin films was achieved.
