| Abstract: | The photoelectrochemistry properties of TiO 2 nanocrystalline thin films were studied. The transport kinetics of photoinduced carries at the nanocrystalline thin film electrode/electrolyte interface was investigated by the analysis of the transient photocurrent response. The slow response of photocurrent of the TiO 2 nanocrystalline thin film electrode upon the illumination was influenced by its surface state, which was attributed to the trap saturation effects. |
