The bulk-heterojunction (BHJ) system that uses a π-conjugated polymer as an electron donor, and fullerene derivative acceptor, is widely used in organic solar cells (OSCs) to facilitate efficient charge separation extraction. However, the conventional BHJ still suffers from unwanted phase segregation caused by existence of significant differences surface energy between two components extraction layer during film formation. In present work, we demonstrate sophisticated control fast film-growth kinetics can be achieve uniform distribution donor acceptor materials OSCs without undesirable separation. Our approach involves depositing solution onto spinning substrate, thus inducing rapid evaporation solvent fast-growth process prevents migrating toward layer, thereby enabling homogeneous within film. based on thin are found exhibit substantial increases JSC, fill factor, PCE up 11.27 mA/cm2, 66%, 4.68%, respectively; this last value represents remarkable 17% increase compared OSCs.

Abstract Ternary organic solar cells (T‐OSCs) based on energy transfer can significantly boost the light absorption efficiency, thereby improving their power conversion efficiency (PCE). However, uncontrolled distribution of third component in bulk heterojunction (BHJ) device often results low ( E FRET ), and also tends to compromise interpenetrating network structure active layer. Herein, a localized deposition strategy is proposed establish with controlled (CDBHJ). Take PM6:Y6:IBC‐F for example, IBC‐F serves as donor PM6 acceptor. Compared BHJ‐based devices, proportion within phase increases from 25.1% 72.7%, enhancing 46.5% 66.8% CDBHJ‐based devices. Furthermore, improves crystallization separation kinetics during film‐forming process. Thus, exhibits superior exciton generation, diffusion, dissociation process, along higher more balanced charge transport. Consequently, achieves PCE 18.29%, which ranks among best PM6:Y6‐based T‐OSCs.
