Abstract: In the fabrication of TiO₂ film electrodes for dye-sensitized solar cells using screen-printing technique, the composition of TiO₂ slurry plays an important role in film microstructure and J-V curve of the solar cells. One of anhydrous TiO₂ slurry was used to prepare anode film by screen-printing technique in this paper, and it was applied in dye-sensitized solar cells. Experimental results show that the addition of Triton X-100 can influence the morphology of TiO₂ film obviously as well as the performance of solar cell. It could be concluded that deficient or excessive addition of Triton X-100 would result in the decrease of open circuit voltage, short circuit current, fill factor and conversion efficiency. Good performance of solar cell can be obtained at the Triton X-100 amount of 0.8 mL in 3 g P25.
