Triton X-100对染料敏化太阳电池性能影响的研究

采用无水相体系的胶体通过丝网印刷工艺制备TiO2薄膜电极,研究发现曲拉通(TritonX-100)可以明显改变TiO2电极显微结构,且对染料敏化太阳电池的性能影响显著.过少或过多的曲拉通都将导致开路电压、短路电流、填充因子以及效率的降低.由3gP25粉末配制的胶体中,曲拉通适宜的加入量约为0.8mL.

Influence of Triton X-100 on the Performance of Dye-Sensitized Solar Cell

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.
