摘　　要：采用溶液浸渍法在ITO导电玻璃表面的多孔TiO2薄膜上沉积了FeS2薄膜。使用Fe2O3粉末保护裸露在外的ITO导电膜在硫气氛中热处理后,制得了FeS2/TiO2复合薄膜。应用B531/H数显测厚指示表、数字式四探针测试仪、XJCM-8太阳电池测试仪等研究了FeS2/TiO2复合薄膜的厚度、ITO导电玻璃的电阻率以及FeS2/TiO2复合薄膜的光电性能。结果表明:此方法制得的FeS2/TiO2复合薄膜具有良好的光电性能;且ITO导电膜的电阻率变化较小。因而适宜制备色素增感太阳能电池(DSSC)。FeS2 thin films were deposited on porous surface of TiO2 on ITO conducting glass by solution dipping method. FeS2/TiO2 composite thin films were obtained by annealing under sulfur atmosphere and by making use of Fe2O3 powder to protect uncovered ITO conducting film. Thickness of FeSE/TiO2 composite thin films, resistance of ITO conducting glass and photoelectric performance of FeSE/TiO2 composite thin films prepared with Different conditions were investigated by XRD, B531/H digital thickness mater, four point resistance probes and XJCM -8. The results indicate that FeS2/TiO2 composite thin films with excellent photoelectric performance can he obtained by this method; resistance of ITO conducting film changes little. Therefore , this kind of film is suitable for preparing dye - sensitized solar cells （DSSC）
