Vertical phase-separated active layer morphology is essential for organic solar cells (OSCs), which can be effectively achieved through layer-by-layer (LbL) processing, enabling independent optimization of donor and acceptor layers. Here, we present a novel strategy to optimize the D18/L8-BO-based OSCs by incorporating polyfluoroquinoxaline-type polymer additives. Three quinoxaline-based polymers with varying fluorination contents, namely, P2FQx, P3FQx, P4FQx, were synthesized evaluated. Although these showed limited performance as standalone materials in bulk heterojunction (BHJ) devices, their use additives LbL-OSCs significantly enhanced device efficiency. These promoted D18 aggregation, L8-BO penetration, facilitated formation vertically interpenetrating donor/acceptor network. Among additives, P2FQx demonstrated best performance, an optimized achieving champion power conversion efficiency (PCE) 20.13% well high fill factor (FF) 80.13%. Our results highlight potential rationally designed address morphology-related challenges provide pathway further development high-performance scalable photovoltaic devices.

Abstract Regulating blend morphology in photoactive films is essential for enhancing the power conversion efficiency (PCE) of organic solar cells (OSCs). However, achieving precise control over remains a significant challenge due to difficulty simultaneously controlling thermodynamic and kinetic parameters that govern formation. In this study, series new small‐molecule acceptors (SMAs) employing dual side chain functionalization strategy designed incorporates trifluoromethyl (CF 3 ) phenyl (Ph) groups: SMA‐CH , SMA‐CF (with CF group), SMA‐Ph‐CF both groups). This approach successfully enables delicate tuning development high‐performance OSCs (PCE = 18.5%). enhances compatibility SMAs with hydrophobic D18 polymer donor, promoting formation intermixed donor/acceptor domains efficient charge generation. Meanwhile, improves SMA aggregation crystallinity, facilitating strong interconnected assembly transport.
