Abstract:

采用低温水溶液法制备ZnO纳米花,将其与TiO2纳米颗粒以不同的质量比混合制备成复合浆料,采用刮涂法涂敷在掺氟的SnO2透明导电玻璃(FTO)上制备ZnO纳米花-TiO2纳米颗粒复合薄膜光阳极,与Pt对电极和电解质组装成染料敏化太阳能电池(DSSC)。通过光伏性能和电化学阻抗谱测试分析,研究ZnO纳米花与TiO2纳米颗粒的质量比对电池性能的影响。结果表明:随着光阳极中TiO2纳米颗粒的增加,DSSC的开路电压和填充因子提高,当ZnO与TiO2的质量比为83∶17时,光电转换效率最高达3.20%;ZnO-TO2染料电池的阻抗谱类似于Gerischer阻抗谱,电子的扩散阻抗与背反应复合阻抗相耦合。
