采用丝网印刷的方式制备了染料敏化太阳能电池的TiO2薄膜光阳极、TiO2-ZnO复合薄膜光阳极以及TiO2/ZnO双层薄膜光阳极,研究了ZnO对TiO2薄膜光阳极的调制改性作用。研究结果表明分别以醋酸锌和ZnO直接掺杂制备的TiO2-ZnO复合薄膜光阳极同未掺杂的TiO2薄膜光阳极相比,以醋酸锌为原料制备的复合薄膜光阳极使电池转换效率提高了1倍,而由于微米量级的ZnO的粒径大,用其作原料制得的复合薄膜光阳极反而使电池的转换效率有所降低。以醋酸锌为原料制备的TiO2/ZnO双层薄膜光阳极同TiO2薄膜光阳极相比,电池转换效率提高了13倍,通过性能优化后电池的转换效率达到4.7%。

TiO2 films,TiO2-ZnO composite films and TiO2/ZnO double films as photoanode of dye-sensitized solar cell were prepared by screen-printing technique,and the modulation effect of ZnO on the TiO2 photoanode was studied.The results of the study indicate that conversion efficiency of the solar cell with TiO2-ZnO composite films photoanode prepared with zinc acetate doped is higher than that of with no doped by 1 time,and because of the um magnitude of the large size of ZnO,its composite photoanode make the conversion efficiency of the solar cell decrease.The conversion efficiency of the solar cell with TiO2/ZnO double films photoanode prepared from zinc acetate as raw material is higher than that of without ZnO film layer by 13 times.The conversion efficiency of the cell with TiO2/ZnO double films is 4.7% by optimization.
