摘　　要：Bulk-heterojunction(BHJ)organic solar cells(OSCs)showcase great advantages in device fabrication via low-cost and convenient solution-processing techniques for diverse applications(e.g.,flexible and semitransparent devices)[1,2].非富勒烯受体是推动有机太阳电池器件效率飞速提升的关键.本文通过对经典ITIC分子实施三重侧链工程,简捷合成了最低未占分子轨道(LUMO)能级不变、吸收红移近60 nm的新型受体ITC6-4F. ITC6-4F与PM6二元共混光伏电池实现了15.57%的效率,媲美Y6同类器件(15.7%).与Y6相比,性价比优异的ITC6-4F堪称是对经典光伏材料的点石成金之作.
