Abstract
In a first aspect, the present invention relates to a perovskite material comprising negatively charged layers alternated with and neutralized by positively charged layers; the negatively charged layers having a general formula selected from the list consisting of: LMX, LMX, and LM'X, and the positively charged layers comprising: one or more organic ammonium cations independently selected from monovalent cations Q and divalent cations Q′, or a polyvalent cationic conjugated organic polymer Z, wherein Q, Q′ and Z comprise each a π-conjugated system in which at least 8 and preferably at least 10 atoms participate, L is a monovalent cation, Mare n independently selected metal cations averaging a valence of two, M′are n independently selected metal cations averaging a valence equal to 2+2/n, X is a monovalent anion, and n is larger than 1.
