Redox‐Buffering PEAI‐CeO x Passivation Suppresses Thermo‐Mechanical Degradation in Perovskite Solar Cells Under Rapid Thermal Cycling

George Kwesi Asare, Minwoo Lee, Jimi Adu, Ram Datt et autres

ABSTRACT Perovskite solar cells (PSCs) show critical thermo‐mechanical and defect mediated degradation at interfaces, limiting their deployment in terrestrial high‐temperature and space‐like environments. This study presents a dual‐function interfacial passivation strategy that combines nanoparticle cerium oxide (CeO x ) with phenylethylammonium iodide …
