采用旋涂法研制了Ag浆SC100-ZnO混合薄膜,系统研究了不同混合比例SC100∶ZnO薄膜作为电子传输层或光散射层对聚合物太阳能电池器件性能的影响, 并讨论了其中存在的物理机制。研究发现, 采用少量SC100(1%和2.5%)混合的薄膜作为光散射层, 可以提高器件的性能参数(短路电流密度和填充因子), 器件的光电转换效率分别提高了4.4%和5%。

The silver paste SC100-ZnO hybrid film was prepared and introduced as an electron transport layer or a light scattering layer into the polymer solar cells. The effects of different mixing ratios of SC100∶ZnO on the performance of polymer solar cell devices were systematically studied, and the physical mechanism was discussed. The study found that the device parameters (short circuit current density and fill factor) of the devices can be improved by mixing a small amount of SC100 (1% and 2.5%) in ZnO film as a light scattering layer. As a result, the corresponding power conversion efficiency of the devices was improved by 4.4% and 5%, respectively.
