摘　　要：纳米TiO2薄膜的组成及结构在很大程度上影响着染料敏化太阳能电池的光电转化效率。从微观结构、复合结构、掺杂、表面处理四方面综述了染料敏化太阳能电池中纳米TiO2薄膜的最新研究成果,探讨了如何通过提高电池中纳米TiO2薄膜对光的吸收、提高电荷的传输效率、降低电荷的复合来优化电池性能。对TiO2薄膜的表面处理,是今后发展的一个主要方向。The performance of dye sensitized solar cells was correlated with the structure and composition of TiO2 semiconductor film. In this article, the research of micro structure, composite structure, doping and surface treatment of nano TiO2 has been reviewed. And the improvement of absorption for light, the transmission efficiency of electric charge and the reduction of the charge composite in dye sensitized solar ceils have also been studied. The surface treatment of TiO2 semiconductor film is considered to be the future development direction.
