摘要：

Dawson-type heteropolyacid {P2MO18VI} and its two-electron heteropoly blue {(P2Mo2Mo16VI)-Mo-V}-doped TiO2 composites have been successfully prepared by a simple sol-gel method and introduced into the photoanode of dye-sensitized solar cells (DSSCs), which results in a significant performance enhancement of DSSCs. The electrochemical impedance spectroscopy (EIS) and open-circuit voltage decay (OCVD) curve were employed to investigate the electron transport and carrier recombination behavior in DSSCs. The results show that doping with {P2Mo18VI} and {(P2Mo2Mo16VI)-Mo-V} could both suppress the dark current and increase the electron lifetime in DSSCs. The performance of DSSCs with both {P2Mo18VI}-doped and {(P2Mo2Mo16VI)-Mo-V}-doped photoanodes is better than that with pure P25 photoanodes and the overall conversion efficiency was improved by 24.48% and 17.19%, respectively.
