摘要
Non-fullerene acceptors have recently attracted tremendous interest due to their potential as alternatives to fullerene derivatives in bulk heterojunction organic solar cells.However,the power conversion efficiencies(PCEs)have lagged far behind the polymer/fullerene system,mainly due to the low fill factor and photocurrent.Here we report two novel perylene bisimide(PBI)acceptors,Sdi PBI-S,Sdi PBI-Se,in which sulfur and selenium atoms were introduced into the perylene core.With a well-established wide-bandgap polymer(PDBT-T1)as the donor,a high efficiency of 7.2%-8.4%with an unprecedented high FF of 70.2%is achieved for solution-processed non-fullerene organic solar cells.Efficient photon absorption,high and balanced charge carrier mobility,and ultrafast charge generation process in PDBT-T1:Sdi PBI-S/Se films account for the high photovoltaic performance.Our results suggest that non-fullerene acceptors have the enormous potential to rival or even surpass the performance of their fullerene counterparts.
