摘要

在这项工作中，我们报告了一项高效有机太阳能电池(OSCs)的降解研究。活性层分别使用PM6作为供体材料和Y7作为受体材料。基于PM6: y7的器件实现了高性能，在一个太阳光照下，新器件的功率转换效率(PCE)高达17.3%。为了更好地了解PM6:Y7的稳定性，我们开发了存储时间内降解过程的分析。888 h后，器件的PCE降至初始PCE的82%。在光照和黑暗条件下，通过电流密度-电压特性(J-V)提取降解过程中的电学参数。

Preliminary Study of the Degradation of PM6:Y7-based Solar Cells

In this work, we report a degradation study of high-efficiency organic solar cells (OSCs). The active layer uses PM6 as a donor and Y7 as an acceptor material, respectively. High performance of the PM6:Y7-based device is achieved with the power conversion efficiency (PCE) of up to 17.3% under 1 sun illumination for the fresh device. To gain a better understanding of PM6:Y7 stability, we developed the analysis of the degradation process over the storage time. The PCE of the device decreased to 82% of the initial PCE after 888 h. The electrical parameters during the degradation process were extracted from the current density – voltage characteristics (J–V) under light and dark conditions.
