Abstract: This paper briefly introduced the dye-sensitized nanocrystalline titanium dioxide solar cell structure, the main principle, on the status at home and abroad, the development trend of the main problems and the prospect of industrialization the future; The impact of its photoelectric conversion efficiency of the key factors, such as cathode materials, nano-titanium dioxide film, dye-sensitized agent, electrolyte solution and anode materials were introduced and reviewed; The two kinds of preparation methods of the counter electrode (platinum) were discussed: electrochemical (constant current law) and thermal decomposition. Photovoltaic devices were fabricated and characterized, and the effect of different preparation methods of Pt on performance were compared, and also was optimized preliminarily.
Keywords:Dye-sensitized; titanium dioxide; constant current law; photoelectric conversion efficiency
