摘要: 采用丝网印刷的方式制备了TiO2纳米晶薄膜, 然后在其上采用浸泡的方式制备了SnO2纳米晶薄膜, 形成TiO2/SnO2膜结构的光阳极并应用于染料敏化太阳能电池。用SEM对样品进行了结构形貌分析, 用电化学工作站研究表征了SnO2的浸泡溶液浓度和浸泡时间对光阳极的调制改性作用。SEM分析表明在TiO2纳米晶薄膜表面生长的SnO2纳米晶薄膜晶粒比TiO2更加细小, 电学性能研究表明TiO2薄膜经过0.4 mol/L SnO2溶液浸泡处理50 min能对TiO2薄膜的结构及性能起到很好的改善作用, 电池的光电转化效率提高了约7%。

Abstract: The effect of SnO2 nanocrystalline coatings on the performance of dye-sensitized solar cells (DSSC) based on TiO2-nanoparticle photoanode was studied. The TiO2-nanoparticle photoanode was prepared by screen-printing technique, and the SnO2 nanocrystalline films were coated on TiO2 nanoparticles by soaking TiO2 photoanodes in SnO2 solution with different concentrations or different time. SEM images indicate SnO2 nanocrystalline films have smaller surface grains than the TiO2 nanocrystalline films. The electrical properties of the films indicate that SnO2 thin films growing on the TiO2 films by soaking TiO2 films in 0.4 mol /L SnO2 solution for 50 min play a positive role on the structure and performance of the TiO2 films, and the conversion efficiency of the solar cell with TiO2/SnO2 photoanode is about 7% higher than that of TiO2 films.

Key words: dye-sensitized solar cell, TiO2 photoanode, SnO2, J-V curve, conversion efficiency
