摘　　要：水热法制备纳米晶TiO2电极,分别用臭氧和AgNO3对TiO2基薄膜电极片进行处理,组装成染料敏化太阳电池。用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、光电子能谱(XPS)测试仪对纳米晶TiO2薄膜进行表征,测试电池的I-V曲线。结果显示,臭氧处理的电池短路电流密度和光电转换效率分别提高了40.5%和64.31%;硝酸银掺杂后电池的短路电流密度和光电转换效率先增大后减小,其中Ag掺杂量为1%时电池的输出性能最佳,其短路电流密度和光电转换效率分别提高了57.46%和48.13%。The nanocrystalline TiO2 electrodes are prepared by hydrothermal method,the TiO2-based thin film electrode sheets are treated with ozone and AgN03 respectively to form a dye-sensitized solar cell.The nanocrystalline TiO2 film was characterized by X-ray diffractometer,scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS).The IV results showed that the short-circuit current density(JSC) and photoelectric conversion efficiency(η) of the ozone-treated cells were increased by 40.5% and 64.31%,respectively.The JSC andη of silver nitrate-doped cells first increased and then decreased.The best output performance of the cells was TiO2/Ag 1%,and the JSC and η of which were increased by 57.46% and 48.13%,respectively.
