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%.

Abstract:

The ZnO photoanode was co-sensitized with cadmium complexe Cd(phen)2(NO3)(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 voltammetry measurement, UV-Visible absorption spectroscopy, fluorescence spectrum, electrochemical impedance spectroscopy and photocurrent-photovoltage curve. The results show that cadmium complexe is suitable for sensitization of ZnO photoanode, 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.
