Title (EN) ORGANIC-INORGANIC HYBRID PEROVSKITE COMPOUNDS
(FR) COMPOSÉS DE PÉROVSKITE HYBRIDE ORGANIQUE-INORGANIQUE
Abstract:
(EN) Photoactive materials comprising organic-inorganic hybrid halide perovskite compounds are provided. Photovoltaic cells and light-emitting devices incorporating the photoactive materials into their light-absorbing and light-emitting layers, respectively, are also provided. The halide perovskites have an amAMX3 perovskite crystal structure, wherein am is an alkyl diamine cation, an aromatic diamine cation, an aromatic azole cation, a cyclic alkyl diamine cation or a hydrazinediium cation; A is a monovalent alkylammonium cation or an alkali metal cation; X is a halide ion or a combination of halide ions; and M is an octahedrally coordinated bivalent metal atom.
(FR) La présente invention concerne des matériaux photoactifs comprenant des composés de pérovskite hybride organique-inorganique d'halogénure. La présente invention porte également sur des cellules photovoltaïques et sur des dispositifs électroluminescents incorporant les matériaux photoactifs dans leurs couches absorbant la lumière et électroluminescentes, respectivement. Les pérovskites d'halogénure présentent une structure cristalline de pérovskite amAMX3, am étant un cation de diamine alkyle, un cation de diamine aromatique, un cation d'azole aromatique, un cation de diamine d'alkyle cyclique ou un cation hydrazinediium; A est un cation alkylammonium monovalent ou un cation de métal alcalin; X est un ion halogénure ou une combinaison d'ions halogénure; et M est un atome métallique bivalent à coordination octaédrique.
