Abstract: A precursor was obtained by hydrolyzing tetrabutyl titanate in hydrochloric acid or acetic acid solution,anatase nano-TiO2 powder was prepared from the precursor by hydrothermal method.Using the nano-TiO2 as the electron transmission medium,a dye-sensitized solar cell(DSC) was assembled.The influence of nano-TiO2 on the photoelectronic properties of the DSC was investigated by measuring XRD,ICP,SEM,TEM,DRS and I-V curve of the solar cell.The result show that the temperature of the hydrothermal play an important role in the photoelectric performance of the DSC,the anatase TiO2 prepared in acetic acid solution shows higher photoelectric performance than others.

Key words: solar cells, dye sensitized, hydrothermal method, anatase TiO2
