摘要：
TiO2 thin films have been deposited on FTO-coated glass substrates using sol-gel technology for application as the work electrode for the dye-sensitized solar cells （DSSC）. The effects of annealing temperature （400~700 oC）on the microstructure, morphology and optical properties of TiO2 thin films were studied. The electrode of DSSC fabricated with TiO2 thin films were characterized by X-ray diffraction （XRD）, scanning electron microscopic （SEM） and Brunauer-Emmett-Teller （BET） analysis. Based on the results, the TiO2 films annealed at 700 oC shows better crystallization, higher porosity and surface area than those of TiO2 films annealed at lower temperature. The higher efficiency （η） of 1.57 % with Jsc and Voc of 5.6 mA/cm2 and 0.65 V, respectively, was obtained by the TiO2 film annealed at 700oC.
