Abstract

Insights into the structure-processing-morphology correlation of PM6:Y-series NFAs (Y6, Y7, Y12, and DTY6) bulk-heterojunction (BHJ) systems processed from a green solvent, ortho-xylene (o-XY), is investigated in comparison with the same blends processed from traditional halogenated solvent, chlorobenzene (CB) and chloroform (CF). The high-performance systems preserved PCEs > 15% all exhibit fast charge carrier extraction, low density of bulk traps as well as long drift length and diffusion length for free charge carriers, which reveals the key factors for OSCs to maintain high PCEs regardless of processing solvents.
