Abstract: Dye-sensitized solar cells (DSC) play a leading role in the third generation photovoltaics 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. This paper studies the influence of different ions doping and different concentration of ion doping on the electrical and optical properties of DSC, through the photoelectric property test of DSC. We learn that Zn2+ doped TiO2 photoanode is the best. At the same time there was an optimum doping concentration which was 0.05% (mole fraction).

Keywords: Anode, Doping, Concentration of Ion Doping, Photoelectric Property
