The long-term stability of perovskite solar cells (PSCs) remains a bottleneck for commercialization. While studies on the stoichiometry and morphology PSCs with regard to performance are prevalent, understanding influence these factors their is lacking. In this work, we evaluate impact cesium formamidinium-based PSCs. We demonstrate that lead iodide (PbI2) formamidinium (FAI) ratio influences under various stress (elevated temperature light). A high molar (PbI2/FAI > 1.1) in precursor displays drastic degradation ISOS-L1 (100 mW/cm2, 25 °C, maximum power point tracking) conditions. However, postdegradation analysis contradicts results. Devices PbI2/FAI ≤ 1.1 stable light, but intermittent current density-voltage characterizations indicate device decreases during storage dark. Migration (I-) ions electron-transport layer (ETL) iodine vacancies (VI-+) hole-transport (HTL) forms localized shunts absorber layer. Pinhole formation, surrounded by FA+-rich regions, explains extent damage comparably aged films. summary, work emphasizes importance reporting different conditions, coupled dark recovery analyses better understand complexities instability real-life conditions such as expected outdoor operation.

Abstract Perovskite solar cells (PSCs), while highly efficient, face stability challenges that hinder their commercial application. These instability issues mainly arise from the fragile nature of Pb─I bonds in perovskites, which easily break under environmental stresses such as heat and light, leading to breakdown [PbI 6 ] framework irreversible degradation. To address these issues, a multifunctional molecule, N 1 ,N 4 ‐bis(2,3,5,6‐tetrafluoro‐4‐iodophenyl)terephthalamide (FIPh‐A), is designed synthesized enhance perovskite films devices. FIPh‐A molecule possesses carbonyl, amino, iodotetrafluorophenyl groups bind stabilize Pb 2+ ions 4− octahedra structure, preventing ion migration films. The activation energy increases obviously 0.28 eV 0.39 by adding verified experiment results. residual strain also released efficiently introducing into characterized grazing incidence X‐ray diffraction. champion PSC with achieves power conversion efficiency 24.60%.
