研究了 TiO2表面染料的吸附状态不同时，染料敏化太阳能电池(DSC)的光电转换性能，并采用电化学交流阻抗技术(EIS)考察了不同染料吸附状态下DSC中的电子界面复合效应。结果表明，在非饱和吸附染料状态下，通过调整 TiO2薄膜表面染料分子吸附量，可以降低界面电荷复合效应，使电子在 TiO2薄膜的传输过程中寿命增加，从而提高DSC的填充因子。

The photoelectric conversion properties of dye-sensitized solar cells (DSC)with different status of dye adsorption on the TiO2 surface were investigated.The recombination effect of electrons in the DSC under differ-ent status of dye adsorption was characterized by electrochemical impedance spectra (EIS).The results showed a decline of electron recombination at interface under the condition of unsaturated dye adsorption through adj us-ting the dye loading amount on the TiO2 film,which increased the lifetime of electrons transport in the TiO2 film and enhanced the fill factor of the DSC.
