摘　　要：应用浸渍涂膜法制备了CuI固体电解质薄膜,组装了DSSC电池。用扫描电镜观察了CuI薄膜的表面形貌,四探针电阻仪测定了CuI薄膜的电阻率,XJCM-8太阳电池测试仪测试了DSSC电池的性能结果表明:添加适量的离子液体可以有效地抑制CuI晶粒的生长;提高CuI晶粒与多孔TiO2薄膜孔径尺寸的相配度;减小CuI薄膜的电阻率。这些都是影响CuI固体电解质色素增感太阳能电池性能及稳定性的重要因素。CuI solid electrolyte films were prepared by dipping coating method. DSSC was made with CuI films as solid electrolyte. Surface morphology and resistance rate of CuI solid electrolyte film were investigated by SEM and four probes resistance rate instrument. The performance of DSSC was measured by XJCM- 8 apparatus. The results indicate that the growth of CuI crystal particles can be inhibited; the matching of crystal particles size of Cul and pores size of porous TiO2 films can be improved; resistance rate of CuI film can be reduced gradually by adding appropriate content of ionic liquid, which are important factors on DSSC＇s performance and stability with CuI solid electrolyte.
