摘　　要：通过优化纳米TiO2多孔薄膜的微结构,改善多孔薄膜表面特性和光利用,优选染料敏化剂,拓宽光谱响应以提高电池的电流密度;降低薄膜厚度、优化电解质组分以提高开路电压;通过改善电子收集以提升电池的填充因子。通过改进制作工艺,最终获得11.12%的染料敏化太阳电池(0.16cm2)光电转换效率。The key materials for dye sensitized solar cells were compared and investigated through the experimental. The microstrueture of TiO2 porous films was optimized to improve the light harvesting. The dye was optimized to expand the spectroscopy response and therefore to enhance the photocurrent density. The open circuit voltage was increased by decreasing the film thickness and optimizing the electrolyte components. The fill factor was increased by improving the electron collecting. As a result, a power conversion efficiency of 11.12% was obtained.
