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. Different type n‐type show different applicability conventional inverted OSCs. External dopants further increase hybrid blends. Particularly, ZnO doped dyes achieve superior photoconductivity This review focuses on CILs high‐performance In small molecules polymers, external n‐doped blends as summarized. small‐molecular electrolytes polyelectrolytes, PEI‐/PEIE‐based (including organic‐organic ZnO‐organic) summarized relationships between particular functions chemical structures highlighted. Finally, summary outlook provided.

Abstract Inverted organic solar cells are promising due to their better stability compared conventional structures. Donors with low synthetic complexity desirable lower costs. However, inverted devices rarely used in low‐complexity systems. To investigate the reasons, PTQ10:BTP‐eC9 binary system is benchmarked against high‐complexity PM6:BTP‐eC9 system. In PTQ10:BTP‐eC9, where efficiency of lags structure significantly, distinct wetting layers observed and device Conversely, vertical distribution remains unaffected by changes interlayer materials. The surface always enriched BTP‐eC9, but less for PM6. Importantly, addition PC 71 BM reduces nonuniform composition gradients. As concentration increases, PTQ10 approach that PTQ10:BTP‐eC9:PC (1:1.2:0.4) exhibits negligible differences between (14.01%) (14.49%) architectures. concentration‐gradients aredriven interfacial energy active layer materials casting kinetics case surface. Understanding thermodynamic kinetic aspects provides valuable insights optimizing performance cells, bringing them closer practical applications.
