摘　　要：对染料敏化纳米晶TiO_2薄膜太阳电池的光阳极进行了不同方法的TiCl_4修饰处理,测量了各种修饰处理下的TiO_2太阳电池的光电转换性能。通过准分子脉冲激光(λ=248nm)和氙灯辐照下的开路光电压V_∝随时间的衰减关系,分别研究了单色脉冲和多色连续光激发下的染料敏化TiO_2太阳电池的光电子复合效应,从中明确了TiCl_4修饰对染料敏化TiO_2太阳电池暗电流的调制所起的重要作用。The different methods with TiCl4 solutions were applied for the decoration of TiO2 photoelectric anode in dyesensitized solar cells. The photoelectric performances of the built-up dye-sensitized TiO2 solar cells were investigated with respect to the effect of electrode decoration. By measuring the decay of Vm with the time gone under the 248nm excimer pulse laser as well as the Xenon lamp, the different photoelectron combination effects on two excitation states caused by pulse monochrome and consecutive wavelengths were identified, respectively. It is revealed that the treatment of TiO2 photoelectric anode plays a significant role in reducing dark current of dye-sensitized TiO2 solar cells.
