In this paper, tetraisopropyl titanate and tetra-n-butyl titanate were used as titaniume source to prepare the TiO2 nano-material by the hydrothermal method. The effect of heat treatment temperature on the crystal structure, surface morphology and spectral characteristics of the prepared TiO2 electrode has been studied. The best titaniume source and synthesis conditions are obtained. The results indicated that the crystal structure and particle size of TiO2 have an obvious effect on the performance of DSSC, such as open circuit voltage, short circuit current, fill factor and conversion efficiency. After 450°Сheat-treatment, photoelectric conversion efficiency is 4.36% and tetraisopropyl titanate is more suitable for the preparation of TiO2 electrode for dye-sensitized solar cells.
