英文摘要	Dye-sensitized solar cells (DSC) play a leading role in the third generation photovoltaic devices due to their low cost, easy fabrication process, high conversion efficiency, and good stability. As a media of dye adsorption, electron transport, and electrolyte diffusion, the nanocrystalline semiconductor photoanode plays a key role during light-to-electricity conversion in DSC. Apparently, titania (TiO2) has been most frequently used as a photoanode materials in DSCs. Although other semiconductors such as ZnO, SnO2, and SrTiO3 etc. have also been widely applied in photoanode of DSC, none of them have shown better performance than TiO2. Up to now, a record efficiency of 12.3% for the DSC with TiO2 photoanode has been achieved. However, further improvement of the conversion efficiency of DSC is still a major issue for its application prospects. In recent years, doping TiO2 with metal and nonmetal elements has been considered as a promising way to tailor the electronic properties of TiO2 photoanode in DSC and has succeeded in improving photovoltaic performance of DSC. This article presents an overview on doped nanocrystalline TiO2, including non-metal doped TiO2, transition metal doped TiO2, rare earth doped TiO2, and main-group metal doped TiO2 employed as the photoanode for improving photovoltaic performance of DSC. The influence of foreign-elements doping on the band edge, the trap state distribution, the electron transport process, the recombination reaction, and the light harvesting of TiO2 photoanode are discussed. Lastly, an outlook on the future challenges and prospects of doped nanocrystalline TiO2 materials as the photoanode for DSC are also briefly brought up.
