摘要
染料敏化太阳能电池(DSSCs)因为其制备工艺简单、实用化前景好、成本低、转换效率高等优点而受到广泛关注。简要介绍了染料敏化太阳能电池结构和工作原理,并从电解质、染料敏化剂、对电极和光阳极等方面综述了其各组成部分的研究现状。重点以TiO_2/CeO_2复合光阳极为例,阐述了染料敏化太阳能电池光阳极薄膜材料的发展历程,总结了双层结构薄膜材料的光散射效应、上转换性质、比表面积、光响应能力以及电子传输性能对整个电池性能优化的影响,并对未来染料敏化太阳能电池研究方向和前景进行了展望。
Dye-sensitized solar cells have attracted more and more attention from researchers all over the world,owing to their simple preparation technology,well practical application prospect,relatively low production cost and high conversion efficiency.First,the structure and working principles of dye-sensitized solar cells are described.Then the research status of its individual component is summarized,including electrolyte,dye-sensitizer,counter electrode and photoanode.The main development histories of TiO2/CeO2 composite photoanode are expounded emphatically.The characteristic properties of the materials for double-layered photoanode which influence the performance of the solar cells was thoroughly investigated,such as the light-scattering effect,upconversion luminescent effect,specific surface area,spectral response capability,and charge transfer efficiency.Finally,the future developing trends of dye-sensitized solar cells is put forward.
