合成了一种新型n型小分子FFI-1作为电子受体，取代了溶液法制备有机BHJ太阳能电池中的PCBM。其LUMO水平（约-3.5 eV）既符合阴极的功函数，又增加了器件的V(OC)，使其成为有希望的受体候选。以P3HT: FFI-1 （1:2 w/w）为有源层，LiF/Al为阴极，功率转换效率（PCE）达到1.86%。
A novel n-type small molecule FFI-1 was synthesized as the electron acceptor to replace PCBM in solution-processed organic BHJ solar cells. Its LUMO level (around -3.5 eV) both matches the work function of the cathode and increases V(OC) of the devices, making it a promising acceptor candidate. With P3HT: FFI-1 (1:2 w/w) as active layer and LiF/Al as the cathode, the best power conversion efficiency (PCE) reaches 1.86%.
