| Abstract | Sulfur-doped TiO2 photoanode was prepared by hydrothermal method, and then characterized and analyzed through XRD, UV-vis, and XPS. The results showed that: Sulfur-doped TiO2 doped by sulfur was anatase; Sulfur-doped TiO2 atoms improved visible light absorption ability of TiO2; The performance of DSSCs doped by sulfur improved markedly, in which 0.770 g thiourea sample performed the best. Its open-circuit voltage was 0.72 V, short-circuit current density was 16 mA·cm −2 , and photoelectric conversion efficiency reached 14.82% high. The improvement of efficiency is resulted from the Sulfur-doped which leads to the following effects: more electrons from dye are injected into the TiO2 nanometer crystal, the electron transfer rate is enhanced, therefore short circuit current density of the battery is increased, finally the efficiency of the battery is improved. |
