| Abstract: |
| Objective To study influences of preparation method of photoelectric functional coating on photoelectric conversion efficiency of TiO2 thin films. Methods The FTO thin film photoelectrodes were prepared by spraying. Based on observation of surface appearance, the photoelectric conversion efficiency of photoelectric materials was estimated by studying changes of light current and photopotential and compared with photoelectrode prepared by spot coating and electrophoresis. Results The TiO2 FTO thin-film prepared by spraying has better performance than electrode prepared with the other two methods. In 3.5% NaClsolution, the photoelectricity change was more stable, the pressure drop was larger than 500 mV and the light current changed by more than 60 μA/cm2. Conclusion Preparing photoelectrode by spraying could improve the photoelectrochemical efficiency of the semiconductor powder material. It is a thin film photoelectrode preparation method which could be practiced. |
