Molecular aggregation in thin films demonstrates a profound effect on the photovoltaic performance of organic photovoltaics (OPVs). Here, we develop a novel two-dimensional atomic crystal CdPS 3 , and comprehensively investigate its effect on the thin film aggregation and photovoltaic performance of PM6:Y6 −based OPVs. CdPS 3 tends to be distributed in PM6 domain, inducing a J- to H-aggregation transformation of PM6 molecules. H-aggregation resulted in finer phase separation, tighter molecular packing in PM6:Y6 blend membranes. Such morphology...
