Understanding the intrinsic phase stability and inherent band gap of formamidinium lead triiodide (FAPbI3 ) perovskites is crucial to further improve performance perovskite solar cells (PSCs). Herein, we explored α- δ-phase transition FAPbI3 single crystals grown by an inverse temperature solubility method. We found that residual γ-butyrolactone solvents in inner empty space crystal accelerate at kinetics. By adopting 2-methoxyethanol as solvent, over 2000 h stable α-FAPbI3 could be acquired. This proves although regarded unstable thermodynamics, it own excellent kinetic without any doping or additives because slow solid instead fast assisted solvents. Furthermore, revealed bulk with a size above 100 μm can have 1.41 eV. Thus, our work provides key scientific guidance for high-performance -based PSCs.

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.
