Abstract

Perovskite solar cells have shown remarkable performance and improvements in terms of solar cell efficiency. The ETL material is one of the important components in perovskite solar cells in conducting electrons to produce current. Here, ZnO was used as ETL material in a perovskite solar cell using the SCAPS 1D simulation software. The ZnO ETL showed poor cell efficiency due to its reaction with the perovskite material. A small amount of Al doped into ZnO was introduced to enhance the physiochemical properties of the ZnO against perovskite materials. Al concentrations were varied between 1 and 4 mol% to observe the effect on cell efficiency. Compared with a conventional ZnO ETL solar cell with 0 mol% Al perovskite, the Al-doped based solar cell showed better performance. Meanwhile, perovskite solar cells with 1 mol% Al-doping and appropriate layer thickness showed the best cell performance in improving the charge transport mechanism, resulting in increased cell efficiency. Thus, the parameters studied can be a guide in the fabrication process.

铝对钙钛矿太阳能电池中ZnO电子传递层的影响

钙钛矿太阳能电池在太阳能电池效率方面表现出了显著的性能和改进。ETL材料是钙钛矿太阳能电池中导电电子产生电流的重要组成部分之一。在这里，使用SCAPS 1D模拟软件将ZnO用作钙钛矿太阳能电池的ETL材料。ZnO ETL由于与钙钛矿材料发生反应，电池效率较低。将少量Al掺杂到ZnO中，提高了ZnO对钙钛矿材料的理化性能。Al浓度在1 ~ 4 mol%之间变化，观察对细胞效率的影响。与含有0 mol% Al钙钛矿的传统ZnO ETL太阳能电池相比，Al掺杂基太阳能电池表现出更好的性能。同时，钙钛矿太阳能电池中掺杂1mol % al和适当层厚的钙钛矿太阳能电池在改善电荷输运机制方面表现出最好的电池性能，从而提高了电池效率。因此，所研究的参数可以指导加工过程。
