Phase-pure perovskite-type SrTiO3, CaTiO3 and BaTiO3 electrodes have been applied for dye-sensitized solar cells, to obtain higher VOC than TiO2 electrode. Furthermore, TiO2/SrTiO3 and TiO2/BaTiO3 composite electrodes have been also prepared. SrTiO3, CaTiO3 and BaTiO3 powders synthesized by solid-state reaction method at 1200°C for 2 h were used to prepare the solar cells. Phase-pure SrTiO3 and BaTiO3 cells showed higher VOC than that from TiO2, but showed lower JSC and efficiency. To utilize the positive effect to increase the VOC, P25 TiO2/SrTiO3 and P25 TiO2/BaTiO3 composite DSC were prepared. For each series, ~30 wt % addition was favorable to increase the photo-electric conversion efficiency.
