Abstract Organic solar cells (OSCs) have shown great applications potential in flexible/wearable electronics, indoor photovoltaics and so on. The efficiencies of single‐junction OSCs exceeded 19%, making the commercialization brighter. Large‐area printing fabrication is a key way to OSCs, solution‐processed thickness‐insensitive cathode interlayers (CILs) are urgently needed for large‐area fabrication. High electron mobility interfacial materials (CIMs) critical enable CILs. N‐type self‐doped characteristics can endow organic CIMs with high mobility.

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.
