Non-fullerene acceptors have recently attracted tremendous interest because of their potential as alternatives to fullerene derivatives in bulk heterojunction organic solar cells. However, the power conversion efficiencies (PCEs) lagged far behind those polymer/fullerene system, mainly low fill factor (FF) and photocurrent.

A novel perylene bisimide (PBI) dimer-based acceptor material, SdiPBI-S, was developed. Conventional bulk-heterojunction (BHJ) solar cells based on SdiPBI-S and the wide-band-gap polymer PDBT-T1 show a high power conversion efficiency (PCE) of 7.16% with open-circuit voltage 0.90 V, short-circuit current density 11.98 mA/cm(2), an impressive fill factor 66.1%. Favorable phase separation balanced carrier mobilites in BHJ films account for photovoltaic performance. The results demonstrate that...
