Preparation of TiO2 Photoelectric Thin Films by Solâ€gel Dipâ€coating Method

Abstract

TiO2 thin films were fabricated by a solâ€gel dipâ€coating method. The surface morphology, crystal, light transmittance and photoelectric properties of the films were characterized by scanning electron microscope (SEM), Xâ€ray diffraction (XRD), film transmittance tester and solar cell IV test system. It shows from the results that the solâ€gel derived TiO2 film is transparent and smooth. After sintered at 550ô€”¨ , 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.
