ABSTRACT Layer‐by‐layer (LBL) process has emerged as a promising method in the advancement of organic photovoltaics, emphasizing scalability and reproducibility. More importantly, it provides enhanced morphological control for boosting carrier mobility ( μ ) power conversion efficiency. By employing multiscale approach that combined first‐principles calculations, molecular dynamics simulations, kinetic Monte Carlo methods, relationship between LBL morphology engineering donor/acceptor (PM6/L8‐BO) thin films is elucidated. During solvent evaporation, order solid‐phase formation was top surface, bottom region, then middle region. The early solid precipitation from precursor solutions acceptor, resulting well‐ordered arrangement reducing energy disorder acceptor LUMO levels. Furthermore, difference disorders A/D blend region pure A or D domains enabled to balance electron hole mobilities, thereby mitigating charge accumulation recombination.

The future applications of organic solar cells (OSCs) necessitate a thorough consideration their ambient stability and processability, particularly for large area air-processed engineering, but water-induced degradation active layer critically restricts its development. To surmount this hurdle, water-obstructing guest (WOG) strategy is proposed to attenuate the interaction with water molecules, reduce defects in blend films, enhance devices under high relative humidity (RH) conditions by introducing siloxane-containing polymer D18-SiO. In addition suppressing trap density, WOG hydrophobic low surface free energy characteristics, forms capping that blocks moisture penetration while preserving ideal nano-micromorphology crystallinity tight packing properties. Power conversion efficiencies (PCE) >19% reported spin coating OSCs fabricated across an RH range 20 90%, PCE >17% blade at 90% RH. D18-SiO, serves as protective barrier device stability, corresponding unencapsulated retained 80.7% initial performance air (≈ 40% RH) after 600-h maximum power point tracking continuous light illumination, showcasing great potential designing large-scale production OSCs.
