摘要：
A stepwise co-sensitization of a TiO2 mesoporous film in conjunction with two dye molecules using different sequences of adsorption for achieving a complementary spectral characteristic is investigated for application to a low-temperature fabrication plastic dye-sensitized solar cell (plastic DSSCs) The stepwise co-sensitization by monomolecular adsorption of N719/FL and black dye/FL show enhanced photovoltaic performances for the pertinent plastic DSSCs compare with that of the cell with the corresponding individual dyes The optimal conversion efficiencies of plastic DSSCs with N719/FL and black dye/FL are found to be 5 10% and 3 78% respectively which are higher than those of the cells with the corresponding individual sensitizers The incident photon-to-current conversion efficiency (IPCE) and electrochemical impedance spectroscopy (EIS) are also used to analysis these behaviors (C) 2010 Elsevier B V All rights reserved
