摘要/Abstract

摘要： 染料敏化太阳电池由于其较高的光电转换效率和低成本等因素正越来越受到人们的重视,当前其技术发展最为核心的问题是如何减少暗电流、进一步提高其光电转换效率.本工作对染料敏化太阳电池的光阳极进行了不同方法的TiCl4修饰处理,测量了各种不同修饰处理下的TiO2太阳电池的光电转换性能.通过248?nm波长的准分子脉冲激光辐照下的开路光电压Uoc随时间的衰减变化关系,研究了单色脉冲激光下的染料敏化TiO2太阳电池的光电子复合效应,从中明确了TiCl4修饰对染料敏化TiO2太阳电池暗电流的调制所起的重要作用.

Abstract: Dyesensitized solar cells (DSC) have gained more and more attentions due to its high efficiency, low cost, relative ordinary execution technique and steady performance. Currently, the most important issue for DSC development is to further increase conversion efficiency by reducing dark currents. In this present work, the different TiCl4 processing is used for the decoration of TiO2 photoanode in dyesensitized solar cells. The photovoltaic performance of the builtup dyesensitized TiO2 solar cells was investigated. By measuring the decay of Uoc with the time going after the irradiations of pulse monochrome wavelengths, we analyzed the different photoelectron recombination effects due to excitation states caused by 248 nm excimer pulse laser. It was revealed that the treatment of TiO2 photoanode plays a significant role in reducing dark current and enhancing photoelectronic conversion efficiency of dyesensitized TiO2 solar cells.

Key words: nanocrystalline titania, solar cells, TiCl4 decoration, recombination
