Abstract Compared with conventional devices, inverted organic solar cells (OSCs) generally exhibit superior stability, the electron transport layer (ETL) and interface engineering playing key roles in enhancing both efficiency stability. In this study, tetra‐phenyl porphyrin (TPP), a free base porphyrin, is utilized to modify commercially available tin oxide (SnO₂) nanoparticles, thus creating high‐performance ETL for OSCs. First‐principles calculations characterizations reveal that TPP interacts effectively SnO₂ surface, reduces work function, passivates surface defects, improves conductivity of SnO₂. power conversion (PCE, 15.37%) control PM6:Y6‐based hybrid enables an improved PCE 17.72%. Furthermore, ternary device PM6:L8‐BO:BTP‐eC9 achieves 19.51% (Certificated efficiency: 19.13%, record OSCs). This study presents promising strategy developing highly efficient stable cells.

The most widely used material in electron transport layers (ETL) of inverted organic solar cells (iOSCs) is zinc oxide (ZnO). However, the brittleness, inorganic nature, surface defects, and photocatalytic activity ZnO lead to poor stability iOSCs. Herein, light‐soaking thermal iOSCs are substantially improved by modifying with polyurethane diacrylate (SAR) or urethane acrylate (OCS)‐based ultraviolet (UV) resins. UV resins significantly reduce energy barrier, suppress improve interfacial contact between ETL photoactive layer. Notably, SAR OCS mitigate ZnO, electrical leakage, resistance during photoaging OSCs. As a result, based on modified ZnOs retain over 80% initial efficiency under 1 sun illumination for light soaking 1000 h. Furthermore, surfaces form robust crosslinked network excellent solvent resistant properties, which result enhanced stability. These results reveal that this simple effective approach promising procedure fabricate high‐performance

Abstract Achieving both high efficiency and stability in organic solar cells (OSCs) remains a significant challenge. Inverted structure OSCs, compared to those with normal structure, show great potential for combining enhanced stability. However, despite their improved stability, the efficiencies of inverted OSCs still lag behind conventional largely due performance electron transport layers (ETLs). Herein, water‐soluble hybrid ETL is developed by modifying SnO 2 nanoparticles an aqueous potassium carboxylate salt, PMA. This modification effectively passivates oxygen vacancy defects eliminates light soaking issue observed control device. As result, PM6:Y6‐based device shows improvement from 16.68% 17.85% PMA modification. Notably, exceptional 19.07% achieved PM6:BTP‐eC9‐based using this ETL, marking highest reported date single‐junction OSCs. In addition, all tested demonstrate superior under thermal illumination at maximum power point devices. Furthermore, utilizing water‐processed large‐area module based on PM6:BO‐4Cl fabricated outstanding 15.02%.

Abstract Here, a simple method of applying dimethylformamide (DMF) as cosolvent in the sol‐gel technology is used to improve quality ZnO bulk films. First‐principles calculations show that with addition polar solvent DMF, adsorption energy (E ads ) between and Zn(OH)₂ increases from −1.42 −1.74 eV, which can stabilize existence Zn(OH)₂, thereby promoting synthesis. Besides, elimination amine residues DMF‐ZnO film significantly suppress photocatalytic activity induced by amine‐induced coordination or redox reactions. Inverted organic solar cells (OSCs) based on PM6:Y6 PM6:BTP‐eC9 achieves impressive power conversion efficiencies (PCE) 17.58 18.14%, respectively. Furthermore, benefiting reduced defects ZnO, pseudo‐bilayer heterojunction (PBHJ) devices optimized exhibited superior stability, ETLs maintain 90.28% their initial PCE after 1000 h thermal aging at 85 °C, 80.98% 168 UV aging.
