| Abstract: | TiO2 thin film electrodes of flexible dye sensitized solar cell were successfully prepared by hydrothermal treatment at room temperature. The pastes were consisted of P25 and tetrabutyl titanate sol. The crystal structure and the specific surface area of TiO2 particles hydrolyzed by tetrabutyl titanate sol were analyzed. The surface morphology of photo electrode, absorbance spectra and cell photoelectric performance were measured. It is found that the titanium dioxide hydrosol is composed of anatase phase with specific surface area of 280m2/g. The surface morphology of TiO2 thin film electrode is porous, and the absorbance values of its sensitized absorbance spectra increase. The best photoelectric conversion efficiency of flexible DSSC is 1.32%. |
