Abstract

Abstract:

Photosensitization by composite sulfides and Ru(Ⅱ) complex for TiO2 nanoporous film was investigated with photoelectrochemical methods. The results showed that the conversion efficiency of light to electricity was greatly improved. This could be explained that in the case of this type of photosensitization, the back electron transfer from the TiO2 conduction band to the solution was refrained, thus the loss of electrons was avoided.

Key words: TiO₂ nanoporous film electrode, Photosensitization, Photoelectrochemistry
