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.
