英文摘要	Nanocrystalline ZnO and Zn2TiO4 porous film electrodes were prepared by sol-gel method and spin coating method, and the nanocrystalline porous films were characterized by XRD and SEM. Using ZnPc dye and PbS quantum dots as sensitizers. The nanocrystalline film electrodes of ZnO series and Zn2TiO4 series were prepared separately, and their absorption characteristics observed by UV-vis spectrophotometer. The results showed that ZnPc dye and PbS quantum dots could well sensitize the film electrodes, and the effect of ZnPc dye and PbS quantum dots composite sensitization was optimal. Then, the solar cells were fabricated. In simulation sunlight, the overall photoelectric conversion efficiency by Zn 2TiO4/Q-PbS/ZnPc electrode increased by 22%, relative to the ZnO/Q-PbS/ZnPc electrode's. © (2011) Trans Tech Publications.
