Abstract:

Article Preview

The nanoporous TiO2 film doped Eu3+ were prepared by combining the sol-gel and hydrothermal method, which could be applied to dye-sensitized solar cells(DSSC). The films were characterized by XRD, SEM and UV-vis DRS. DSSC photoelectric properties were evaluated by recording current-voltage characteristics under simulated sunlight illumination. The results indicated that Eu3+-doped TiO2 film electrodes increased short-circuit current and the fill facter availably; when TiO2 doping concentration for Eu3+ was 2.0mol%, a short circuit current of 0.389mA, an open circuit voltage of 0.6006V and a fill factor of 0.60 were obtained, which was remarkably better than of undoped TiO2 film electrode; and the optimal thickness attained in this work was 17.2um.
