摘　　要： 使用水热法制备了一系列不同含量Ag纳米颗粒掺杂的Ag-TiO2复合光阳极的染料敏化太阳能电池,同时,研究了不同含量Ag纳米颗粒掺杂对染料敏化太阳能电池的结构和性能的影响.实验结果表明:Ag的掺入增强了吸附在Ag-TiO2复合光阳极上的染料对光的吸收,显著地提高了对应电池的短路电流.在Ag掺入量为0.20%的时候,对应的电池具有最佳的性能,其短路电流为10.66mA/cm2,开路电压Voc为697mV,光电转换效率为5.59%,显著优于纯TiO2光阳极电池的效率.其性能的改善主要归因于掺入Ag纳米颗粒的表面等离子体共振吸收效应使电池光阳极对光的吸收增强所致. A series of TiO2 photoanodes doped with different amounts of Ag nanoparticIes（NPS） and prepared by the hydrothermal method were used to make a series of dye-sensitised solar cells（DSSCs）. The influence of different amounts of Ag NPS on the structure and performance of DSSCs were investigated. Studies indicated that the incorporation of the Ag NPS significantly enhanced the light absorption of dye loaded on surface of TiO2 film and the short-circuit current density（Jsc）. When the content of Ag NPS was 0.20%, the DSSC achieved the best performance with the largest short circuit current of 10.66 mA/cm^2 , the highest open-circuit voltage of 697 mV and the photoelectric conversion efficiency of 5.59 %, significantly superior to the DSSC with no Ag incorporation. The improved performances were attributed to the enhanced light absorption of dye resulted from the surface plasmon resonance of Ag NPS in photoanode.
