Abstract Accurate interface engineering can effectively inhibit iodide ion migration, thereby improving the stability and photovoltaic performance of perovskite solar cells (PvSCs). The time‐of‐flight secondary‐ion mass spectrometry reveals that in an aged n–i–p‐type PvSC, ions will move toward rear side enter FTO cathode. In this regard, authors describe a simple thermal evaporation strategy for introducing NdCl 3 layer (NdCl ‐IL) at perovskites to interdict iodine migration pathway, leading reduced trap densities throughout whole region. As result, boosted open‐circuit voltage ( V OC ) is achieved, resulting power conversion efficiency (PCE) up 22.16% with negligible hysteresis. ‐IL also enhances device stability, maintaining 83% initial PCE after maximum‐power‐point tracking test 100 h. More encouragingly, certified 21.68% demonstrated on large‐area (1 cm 2 combined 2D/3D passivation strategies.

Fabricating perovskite films with a dominant crystal orientation is an effective path to realizing quasi-single-crystal film, which can eliminate the fluctuation of electrical properties in arising from grain-to-grain variations, and improve performance solar cells (PSCs). Perovskite (FAPbI3 ) based on one-step antisolvent methods usually suffer chaotic orientations due inevitable intermediate phase conversion intermediates PbI2 •DMSO, FA2 Pb3 I8 •4DMSO, δ-FAPbI3 α-FAPbI3 . Here, high-quality film (111) preferred ((111)-α-FAPbI3 using short-chain isomeric alcohol antisolvent, isopropanol (IPA) or isobutanol (IBA), reported. The interaction between IPA leads corner-sharing structure instead edge-sharing octahedron, sidestepping formation these intermediates. With volatilization IPA, FA+ replace situ form along direction. Compared randomly orientated perovskites, dominantly ((111)-perovskite) exhibits improved carrier mobility, uniform surface potential, suppressed defects enhanced photostability. PSCs (111)-perovskite show 22% power efficiency excellent stability, remains unchanged after 600 h continuous working at maximum point, 95% 2000 storage atmosphere environment.
