摘　　要：采用具有紫外光区吸收的金属配合物Cd(phen)2(NO3)(NO2)和N719对ZnO光阳极进行共敏化.结果表明,配合物能够对ZnO光阳极进行共敏化,同时被电解液还原再生,共敏化增加电池对光的吸收,电池光电流密度增加63%,共敏化降低了电池各个界面电阻,有利于电子在界面的传输,电池的光电转换效率提高了37%.The ZnO photoanode was co-sensitized with cadmium complexe Cd（phen） 2（ NOz ） （ NO2 ） absorbed in the ultraviolet light region and dye N719. The performances of co-sensitized dye-sensitized solar cell （DSSC） and the properties of cadmium complexe were investigated by the cyclic vohammetry measurement, UV-Visible absorption spectroscopy, fluorescence spectrum, electrochemical impedance spectroscopy and pho- tocurrent-photovoltage curve. The results show that cadmium complexe is suitable for sensitization of ZnO pho- toanode, and the complexe can be reduced by the electrolyte. The light absorption of DSSC is enhanced and the current density is improved 63% by co-sensitization. The decreased resistance of interface of DSSC is in favor of the electron transport. The conversion efficiency of DSSC based on ZnO photoanode is improved 37% by co-sensitization.
