Abstract

High-performance devices can be achieved by lowering the work function of the cathode electrode. Herein, we synthesized polyelectrolyte that has functionality at the side chain, named PFB. In addition, a p-type dopant, NOBF₄ (nitrosonium tetrafluoroborate), was used to enhance the performance of the polyelectrolyte. This polyelectrolyte was adapted as an interlayer to improve the performances of polymer solar cells (PSCs). The PSCs based on PFB and NOBF₄-PFB demonstrate higher power conversion efficiency (PCE) of 9.41% and 9.51% than pristine PSC using PTB7-Th as a reference (8.7%).

四氟硼酸亚硝鎓作为聚合物太阳能电池夹层的共轭聚合物电解质

摘要

通过降低阴极的功函数可以实现高性能器件。在此，我们合成了在侧链具有功能的聚电解质，称为 PFB。此外，使用 p 型掺杂剂 NOBF ₄ (nitrosonium tetrafluoroborate) 来增强聚电解质的性能。这种聚电解质被用作中间层，以提高聚合物太阳能电池 (PSC) 的性能。基于 PFB 和 NOBF ₄ -PFB 的 PSC 表现出比使用 PTB7-Th 作为参考的原始 PSC (8.7%) 更高的功率转换效率 (PCE) 为 9.41% 和 9.51%。
