摘要： 利用强度调制光电流谱(IMPS)研究了不同微结构的TiO2薄膜在不同的浸泡时间条件下的染料分布情况, 分析了染料分布对染料敏化太阳电池光伏性能的影响. 研究结果表明, TiO2薄膜中确实存在染料的不均匀分布现象, 染料不均匀分布对太阳电池的光伏性能有显著的影响.

Abstract: The phenomena of inhomogeneous dye-adsorption in porous TiO2 film was likely to exist in dye sensitized solar cells(DSC). Dye-adsorption behavior in two kinds of TiO2 films with different microstructure and different adsorbing time was investigated by the Intensity Modulate Photocurrent Spectroscopy(IMPS). The influence of inhomogeneous dye-adsorption for IMPS response and the photovoltaic of DSC was discussed. The result shows that IMPS is a useful tool to detect inhomogeneous dye-adsorption occurred in some TiO2 films. The phenomena of inhomogeneous dye-adsorption had notable influence on the photovoltaic of DSC.

Key words: Intensity Modulate Photocurrent Spectroscopy(IMPS), Dye-sensitized, Solar cell, Dye-adsorption
