The meticulous control of micromorphology in high power conversion efficiency (PCE) polymer solar cells (PSCs) typically relies on halogenated solvents, which pose serious threats to both environmental sustainability and human health. In this work, a green efficient method for fabricating PCE PSCs with halogen-free solvents is developed. By introducing volatile solid additives 1-bromo-2,6-dichlorobenzene (DIB) 1-bromo-2,3,5-trichlorobenzene (TIB) into toluene the aggregation behaviors PM6:L8-BO were meticulously regulated, forming distinct fibrous morphology; detail, vertical direction exhibited pattern acceptor enrichment at top donor bottom, leads enhanced exciton dissociation efficiency, improved charge transport performance, significantly reducing recombination, finally PCEs, as maximum PCEs 18.56 17.67%, respectively, are notably higher than those devices without additives. Furthermore, since can be completely removed from active layer, additive-treated exhibit superior morphology photovoltaic stability. This therefore, unveils straightforward environmentally friendly preparing PSCs, instrumental facilitating large-scale commercialization PSC technology.
