Abstract: TiO2 films with nano-porous structures were obtained by adding the poly-ethylene glycol(PEG) in the TiO2 colloid. Then the as-prepared films were sensitized by the trithiophene carboxylic diacid(TTDA), pentathiophene carboxylic diacid(PTDA), N3[Ru(Ⅱ)L2(SCN)2, L=2,2′-bipyridyl-4,4′-dicarboxylate] dye and the mixture of PTDA and N3 dye, respectively. After fabricating the films into devices, the I-V curves were determined and their photovoltaic properties were studied. The results show that the porous TiO2 films can be sensitized by both TTDA and PTDA effectively, while the film sensitized by the mixture of PTDA and N3 dye has a maximum photo-electric conversion efficiency.
