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
