摘要:
有机太阳能电池（OSCs）中，非稠环电子受体因结构简单、易于修饰和成本低廉受到广泛关注。以氧代苯为核心合成了一种非稠环电子受体(2,5-双((2-丁辛基)氧基)-3-氟-6-甲氧基-1,4-亚苯基)双(4,4-双(2-乙基己基)-4H-环戊二烯并(2,1-b:双(5,6-二氯-3-氧代-2,3-二氢-1H-茚-2,1-二亚基))二丙二腈（L-3）。通过分子工程手段，在苯环上引入具有不同缺电子能力的氟原子和氧原子，并结合π桥和端基优化，制备的L-3分子可实现550~750 nm的中等带隙吸收和较深的最高占据分子轨道（HOMO）能级（-5.71 eV）。与新型聚合物给体材料PBTTzE共混后，能量转化效率为5.87%，开路电压可达到0.96 V，短路电流密度和填充因子分别为12.81 mA·cm-2和47.42%。
Abstract:
In organic solar cells (OSCs)，non-fused-ring small molecule acceptors have garnered significant attention for their simple structures, easy modification and low cost. The non-fused-ring electron acceptor, (2,5-bis((2-butyloctyl)oxy)-3-fluoro-6-methoxy-1,4-phenylene)bis(4,4-bis(2-ethylhexyl)-4H-cyclopentadienyl(2,1-b:bis(5,6-dichloro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile (L-3), was synthesized with oxybenzene as its core. By means of molecular engineering，L-3 was prepared by introducing fluorine and oxygen atoms with different electron-withdrawing capabilities onto the benzene ring and combining with the optimization of p-bridges and end-groups, which could achieve a medium-bandgap absorption of 550－750 nm and a deeper highest occupied molecular orbit (HOMO) energy level of -5.71 eV. When blended with the new polymer donor material PBTTzE, its power conversion efficiency is 5.87%, with an open-circuit voltage of 0.96 V, a short-circuit current density of 12.81 mA·cm-2, and a fill factor of 47.42%.
