摘　　要：在量子点敏化太阳电池的性能研究中,光阳极薄膜的优化一直是研究的重点。除了传统的TiO_2纳米颗粒,通过一些简单实验制备出的纳米管、纳米线阵列,一维核壳纳米结构也被广泛的应用于光阳极中。形貌易于控制的ZnO因与TiO_2具有相似的能带结构和物理性质,又兼具高的电子迁移率而成为比较理想替代物。一维ZnO及其核壳结构半导体材料的制备及性能研究表明,其具有良好的导电性,电荷分离传输效率高,光俘获性能好等优点,已成为量子点敏化太阳电池光阳极研究的重要方向。Among the performance research of Quantum Dot Sensitized Solar Cells, the key research is the optimization of photo-anode film. In addition to the traditional TiO_2 nanoparticles, nanotubes, nanowire arrays and core-shell structure of one dimensional nanostructures prepared by some simple experiment have been widely applied in the photo-anode. At the same time, the researchers are also looking for new replacing semiconductor material. The Zn O thanks to easily controlled morphology, the similar band structure and physical properties with TiO_2, and higher electron mobility at the same time, it has become the ideal alternative, and has been also widely used as photo-anode. The research of preparation and properties based on alternative materials shows that compared with the traditional TiO_2 nanocrystalline, the alternative material has good conductivity, high charge separation efficiency, good performance on optical trapping. Therefore the new material of photo-anode has become an important research orientation of Quantum Dots Sensitized Solar Cells.
