In a dye-sensitized solar cell (DSC), a nano-porous semiconductor layerplays an important role in the performance. It determines open-circuitvoltage and it affects the dye adsorption capacity and charge transfer,which are closely associated with photocurrent and overall performance. TiO2 is the most proper material for nano-porous layer since the firstdevelopment of DSCs. This work focuses on the enhancement of TiO2by doping. Sulfur (S) doping enhances charge transfer and the photoconversionof TiO2. Therefore, the increase in photocurrent andefficiency is expected by S doping. S is doped into TiO2 by hydrolysismethod. The amount of S is varied and their photo-responses areverified. The most effective S doped TiO2 is applied to DSCs. Overallperformance of DSC is enhanced by the addition of S doped TiO2. Especially, the photocurrent is much increased by the improvement oncharge transfer, electron lifetime, and photo-conversion. The photovoltaicproperties of DSCs are investigated with various ratios of undoped and Sdoped TiO2. Finally, a DSC based on undoped and S doped TiO2 ratio of1:1 has the highest efficiency, better than that of a standard DSC basedon undoped TiO2.
