AB - Electron transport layers (ETLs), e.g., metal oxides, organic small molecules, or conjugated polymers, play a vital role in both performance and photo-thermal stability in organic solar cells (OSCs). Herein, we explored hybrid organic-inorganic electron transport materials by forming complexes between typical electron transport layers and ferrocene (Fc)-based molecules. Experimental and theoretical investigations revealed van der Waals interaction between the ETL and Fc compounds, which allows fine-tuning of the electrode work function to improve charge extraction properties and reduce trap-assisted recombination. As a result, OSCs showed improved fill factor (FF) and power conversion efficiency (PCE) for five donor-acceptor blends and three ETLs, with FF and PCE exceeding 80% and 20.1%, respectively. Finally, we demonstrated improved photostability for the hybrid ETLs with devices that retained 80% of their initial performance for 700 h when degraded under operating conditions (ISOS-L-1I).
