Abstract

TiO2 thin films were fabricated by a sol‐gel dip‐coating method. The surface morphology, crystal, light transmittance and photoelectric properties of the films were characterized by scanning electron microscope (SEM), X‐ray diffraction (XRD), film transmittance tester and solar cell IV test system. It shows from the results that the sol‐gel derived TiO2 film is transparent and smooth. After sintered at 550􀔨 , strong crystal anatase phase is formed in TiO2 film, and when used as photo anode, it can improve the photoelectric properties of the Dye sensitized solar cells.
