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%.
