染料敏化太阳能电池的TiO_2光电极的制备及优化

Fabrication and optimization of TiO_2 photoelectrode for dye-sensitized solar cells

讨论了染料敏化太阳能电池的TiO2光电极制备与优化工艺过程,这主要包括TiO2薄膜厚度的优化,利用TiCl4处理导电玻璃以及添加大粒子散射层。研究结果表明,当TiO2光阳极厚度为11μm时,电池的转换效率最高。添加TiO2大粒子散射层后,增强了光阳极对光的吸收,当大粒子散射层为4.4μm时,电池的光电性能最好。对TiO2电极进行TiCl4处理后,电子的传输性能得到改善,光电性能得到较大的提高。

This paper mainly investigated the optimum thickness of TiO2 nanocrystalline film prepared by screen-printing,the effects of large-particle scattering layer and TiCl4 treatment on the characteristic of dye-sensitized solar cell(DSSC).The results indicated that the adding of large-particle scattering layer and the treatment with TiCl4 can improve the photovoltaic performance of DSSC.
