Abstract

Vertically oriented highly crystalline 2D layered (BA)2(MA)n−1PbnI3n+1 (BA = CH3(CH2)3NH3, MA = CH3NH3, n = 3, 4) perovskite thin‐films are fabricated with the aid of ammonium thiocyanate (NH4SCN) additive through one‐step spin‐coating process. The humidity‐stability of the film is certified by the ...
