Alabdulkarem, Ali Z. Alanizi, Abdulrahman A. Ghihab, Konstantinos Petridis, Thamraa M. Alshahrani, George Kakavelakis, Nikolaos Lempesis, Essa A. AlharbiIncorporating α-phase seeds renders α-FAPbI 3 growth highly favorable (Δ E = −0.74 eV vs. −0.15 eV), suppressing the parasitic δ-phase to yield high-performance, stable PSCs.
