摘要: 用电沉积法制得Cu2xIn2-2xSe2(铜铟硒)(0[1]并用EDAX对其组成进行分析。对薄膜电极的光电化学性能、光谱响应、能隙与x的依赖关系进行了研究。借助于现场微区扫描光电流谱观察了热处理、薄膜厚度、光极化对薄膜电极的光电性能影响。研究了Pb(NO3)2有效的浸渍对薄膜光电性能的影响。

Abstract: Cu2xIn2-2xSe2 thin films were prepared by electrodeposition method and characterized by EDAX.The photoelectrochemical behaviour,spectral responset and the dependence of bandgap on x values were studied.SLS (Scanning Laser Spot) was used to observe the effects of annealing treatment,film thickness,and polarization under illumination on photo electrochemical properties of films.The effective dipping in Pb(NO3)2 solution on photo electrochemical behaviour were also studied.

Key words: copper indium selenide, thin films, electrodeposition, photo electrochemistry
