增材工程被认为是提高有机太阳能电池（OSC）功率转换效率（PCE）的一种有价值的方法。然而，能够增强OSCs PCE的有效固体添加剂分子，特别是缺电子构件仍然有限。本文中，两种氰基功能化的高缺电子结构单元，即3,6-二溴吡嗪-2-甲腈（CNPz）和3,6-二溴吡嗪-2,5-二甲腈（DCNPz），具有结构简单、合成容易的特点。用作固体添加剂以优化OSC的性能。研究发现CNPz可以调节分子间相互作用并改善分子堆积，有利于电荷的产生、传输和收集。结果，PTQ10/ m -BTP-PhC6 二元器件实现了 19.67% 的 PCE，位居 OSC 的最高值之列。此外，固体添加剂的普遍适用性在其他有机光伏系统中得到了证明。这些发现为设计和开发新型缺电子固体添加剂以提高 OSC 的效率提供了宝贵的见解。
