Optical spectrum analysis of CulnSe2 Materials applied in Solar Cell

摘要：

　　Since CuInSe2 (commonly called as CIS) materials has become one of most important photovoltaic materials,they are investigated with optical spectroscopies in this paper.The crystal structure,surface microstructure morphology and composition of the samples are analyzed in XRD and SEM with EDX,and the surface electronic state and optical properties of the samples are characterized in X-ray photoelectron spectroscopy (XPS) and Ultraviolet-visible Spectrum instruments.The results show that CIS phase is very uniform,some impurity phases appear in the samples,the atomic distributing percentages of the surfaces of bulk samples are very consistent in the composition ratio forming the crystal phases of the samples,and the atomic electrons are more active than ones in the relevant elements.Furthermore,the thin film of the sample has high solar energy absorptivity,and is suitable for to be manufactured as solar cell.
