The ordered aggregation of non-fullerene small molecular acceptors(SMAs) is critical in determining the charge transport and bimolecular recombination in polymer/SMAs solar cells. However, due to the asymmetric phase separation, the polymers prefer to form crystalline networks, which inhibits the molecular diffusion of SMAs and results in weak crystallinity of SMAs. In poly[(2, 6-(4, 8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1, 2-b:4, 5-b']dithiophene))-alt-(5, 5-(1', 3'-di-2-thienyl-5', 7'bis(2-ethylhexyl)benzo[1', 2'-c:4', 5'-c']dithiophene-4, 8-dione))](PBDB-T)/9-bis(2-methylene-((3-(1, 1-dicyanomethylene)-6, 7-difluoro)-indanone))-5, 5, 11, 11-tetrakis(4-hexylphenyl)-dithieno[2, 3-d:2', 3'-d']-s-indaceno[1, 2-b:5, 6-b']dithiophene(IT-4F) blends, crystallization of IT-4F could be improved by tetrahydrofuran solvent vapor annealing, while crystallization of PBDB-T could be enhanced by thermal annealing at 150℃. Hence, the prior crystallization of IT-4F could be realized by regulating the sequence of two post annealing methods, which facilitates the diffusion of IT-4F and is benefit for the formation of interpenetrating network. The optimization of the film morphology reduced the bimolecular recombination and resulted in an improved device performance from 5.95% to 7.18%.
