| 英文摘要 | High-performance ternary organic solar cells are fabricated by using a widebandgap polymer donor (bithienyl-benzodithiophene-alt-fluorobenzotriazole copolymer, J52) and two well-miscible nonfullerene acceptors, methyl-modified nonfullerene acceptor (IT-M) and 2,2'-((2Z, 2' Z)-((5,5'-(4,4,9,9-tetrakis-(4-hexylphenyl)-4,9-dihydros-indaceno[1,2-b: 5,6-b'] dithiophene2,7-diyl) bis(4-((2-ethylhexyl) oxy)thiophene-5,2-diyl))bis(methanylylidene)) bis(3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile (IEICO). The two acceptors with complementary absorption spectra and similar lowest unoccupied molecular orbital levels show excellent compatibility in the blend due to their very similar chemical structures. Consequently, the obtained ternary organic solar cells (OSC) exhibits a high efficiency of 11.1%, with an enhanced short-circuit current density of 19.7 mA cm(-2) and a fill factor of 0.668. In this ternary system, broadened absorption, similar output voltages, and compatible morphology are achieved simultaneously, demonstrating a promising strategy to further improve the performance of ternary OSCs. |
