摘要：

Mn salts[MnSO4]-doped TiO2 electrodes thin film was synthesized by the hydrothermal method. To prepare the working electrode, The TiO2 or Mn-doped TiO2 slurry was coated onto the fluorine-doped tin oxide glass substrate by the doctor blade method and was then sintered at 450 degrees C. X-ray photoelectron spectroscopy (XPS) data indicated that the doped Mn ions exist in forms of Mn7+. This study show a photovoltaic efficiency of 5.15%, which is higher than that of the undoped TiO2 thin film (4.14%) and increase photovoltage and fill factors by 13.2% from 455 mV to 515mV, 39.3% from 499 to 695 respectively.
