摘要：
Zn-doped SnO2 nanocrystals under hydrothermal conditions were synthesized and subsequently the photoanodes were prepared via the screen printing technology for dye-sensitized solar cells. The effect of Zn-doped SnO2 on the performance of dye-sensitized solar cells was investigated. It is found that Zn doping into SnO2 can induce a negative shift in the flat-band potential and enhance the isoelectric point. As a result, the power conversion efficiency(PCE) of 4.2% was achieved for 2% Zn-doped SnO2 based dye-sensitized solar cell compared with undoped SnO2 based dye-sensitized solar cell. The enhancement in performance was ascribed to improve photogenerated electron lifetime(τe) and dye-uptake capabilities. Moreover, after the TiCl4 treatment of the photoanode, the 2% Zn-doped SnO2 based dye-sensitized solar cell exhibited an impressive power conversion efficiency of 7.7%. © 2021, Science Press.
