TL;DR: In this paper, the authors showed that α-CsPbI3 ((C4H9NH3)2Csn-1PbnI3n+1) with nominal layer thicknesses of n = 1, 2, 3, and 4 can be deposited at temperatures as low as 100 °C, substantially below the phase-transition temperature of bulk α-CpbII3, and they demonstrated that incorporating solvents with high complexation strength into the precursor solution promotes the formation of intermediate phases within the thin film, slowing down LHP
