CdS/CdSe Co-sensitized Solar Cells Based on Hierarchically Structured SnO(2)/TiO(2) Hybrid Films

SnO(2) nanosheet-structured films were prepared on a fluorine-doped tin oxide (FTO) substrate using ZnO nanosheet as template. The as-prepared SnO(2) nanosheets contained plenty of nano-voids and were generally vertical to the substrate. TiO(2) nanoparticles were homogeneously deposited into the int...

description SnO(2) nanosheet-structured films were prepared on a fluorine-doped tin oxide (FTO) substrate using ZnO nanosheet as template. The as-prepared SnO(2) nanosheets contained plenty of nano-voids and were generally vertical to the substrate. TiO(2) nanoparticles were homogeneously deposited into the intervals between the SnO(2) nanosheets to prepare a hierarchically structured SnO(2)/TiO(2) hybrid film. The hybrid films were co-sensitized with CdS and CdSe quantum dots. The sensitized solar cells assembled with the SnO(2)/TiO(2) hybrid film showed much higher photoelectricity conversion efficiency than the cells assembled with pure TiO(2) films. The lifetime of photoinduced electron was also investigated through electrochemical impedance spectroscopy, which showed that the SnO(2)/TiO(2) hybrid film electrode is as long as the TiO(2) film electrode.
