摘要:
通过静电纺丝技术,制备TiO2光阳极,在该光阳极上用连续离子吸附与反应法制备CdS/ZnS量子点,并与Pt对电极、多硫化合物电解液组装成量子点敏化太阳能电池(QDSCs)。利用ZnS比CdS导带高的特点,制备CdS/ZnS共敏化量子点。利用XRD对光阳极进行物相分析,SEM和EDS进行形貌和元素成分表征,并将组装后的电池通过伏安特性曲线(J–V)进行光电性能分析。结果表明:量子点的引入对TiO2的晶型影响不大;CdS/ZnS量子点成功的附着在TiO2光阳极表面;通过比较不同循环沉积次数的CdS与ZnS量子点光阳极的光电性能,先对CdS循环浸泡7次、后对ZnS循环浸泡5次数的量子点,光电性能最优,拥有最高的开路电压(0.87 V)和光电转换效率(1.09 %),与单独的CdS量子点敏化太阳能电池相比较,光电转换效率提高了71.56%。
