采用简单的离子交换沉积法制备了SnS敏化的纳晶TiO2光阳极.通过SEM、XRD、UV-Vis等手段对光阳极的表面形貌,晶态结构,紫外-可见吸收和散射性能进行表征.并分别以聚苯胺和铂为催化剂制备对电极,以含碘氧化还原电对和硫氧化还原电对溶液为电解质,组装SnS敏化太阳能电池,对其光电性能进行研究.通过比较不同光阳极、电解质和对电极的组合,发现用光阳极为离子交换沉积9次SnS的纳晶TiO2膜,对电极为聚苯胺不锈钢网压片膜,电解质为含硫氧化还原电对溶液组装的太阳能电池光电性能最佳,其短路电流、开路电压、填充因子和光电转换效率分别达到4.59 mA/cm2、0.547 V、0.505和1.27％.
