A new and highly efficient cathode interlayer material for organic photovoltaics (OPVs) was produced by integrating C60 fullerene monomers into ionene polymers. The power of these novel “C60‐ionenes” for interface modification enables the use of numerous high work‐function metals (e.g., silver, copper, and gold) as the cathode in efficient OPV devices. C60‐ionene boosted power conversion efficiencies (PCEs) of solar cells, fabricated with silver cathodes, from 2.79 % to 10.51 % for devices with a fullerene acceptor in the active layer, and from 3.89 % to 11.04 % for devices with a non‐fullerene acceptor in the active layer, demonstrating the versatility of this interfacial layer. The introduction of fullerene moieties dramatically improved the conductivity of ionene polymers, affording devices with high efficiency by reducing charge accumulation at the cathode/active layer interface. The power of C60‐ionene to improve electron injection and extraction between metal electrodes and organic semiconductors highlights its promise to overcome energy barriers at the hard‐soft materials interface to the benefit of organic electronics.

用悬垂富勒烯将爱奥尼亚聚合物转变为高效的阴极夹层
通过将C 60富勒烯单体整合到紫罗烯聚合物中,生产出一种用于有机光伏(OPV)的新型高效阴极夹层材料。这些新颖的“ C 60-紫罗兰烯”用于界面修饰的能力使得可以将多种高功函数金属(例如银,铜和金)用作有效的OPV器件的阴极。C 60ion离子烯将使用银阴极制造的太阳能电池的功率转换效率(PCE)从有源层中具有富勒烯受体的器件的2.79%提高到10.51%,将非富勒烯受体的器件的功率转换效率从3.89%提高到11.04%在有源层中,证明了该界面层的多功能性。富勒烯部分的引入极大地改善了紫罗烯聚合物的电导率,通过减少阴极/活性层界面上的电荷积累为装置提供了高效率。C 60紫罗兰能改善金属电极与有机半导体之间的电子注入和提取的能力,突显了其克服硬软材料界面的能垒以实现有机电子优势的承诺。
