A star-shaped electron acceptor based on porphyrin as a core and perylene bisimide as end groups was constructed for application in non-fullerene organic solar cells. The new conjugated molecule exhibits aligned energy levels, good electron mobility, and complementary absorption with a donor polymer. These advantages facilitate a high power conversion efficiency of 7.4 % in non-fullerene solar cells, which represents the highest photovoltaic performance based on porphyrin derivatives as the acceptor.
一种基于卟啉作为核心和并五苯二酰亚胺作为端基的星形电子受体被构建用于非富勒烯有机太阳能电池。这个新的共轭分子具有排列整齐的能级、良好的电子迁移率和与给体聚合物互补的吸收。这些优势使非富勒烯太阳能电池的功率转换效率达到了 7.4%，这是基于卟啉衍生物作为受体的最高光电性能。
