Abstract: A process of forming a photoactive layer of a planar perovskite photoactive device comprising: applying at least one layer of a first precursor solution to a substrate to form a first precursor coating on at least one surface of the substrate, the first precursor solution comprising MX2 and AX dissolved in a first coating solvent, wherein the molar ratio of MX2:AX=1:n with 0
