Title
(EN) COMPOSITIONS COMPRISING PEROVSKITE AND NON-PEROVSKITE
(FR) COMPOSITIONS COMPRENANT DE LA PÉROVSKITE ET DE LA NON-PÉROVSKITE
Abstract
(EN) Compositions comprise a perovskite and a non-perovskite. Perovskites comprise AxA'yA''(1-x-y)BX3, and non-perovskites may comprise A", B and X, where A is a first cation, A' is a second cation, A" is a third cation, B is a fourth cation, X is an anion. In some instances, A, A', and A'' are each independently (NH2)2CH+, CH3NH3+, Cs+, Rb+, or (NH2)2(C=NH2)+, with the proviso that A, A', and A'' are each different. The perovskite may have a first crystal structure in which the anion is corner-sharing, the non-perovskite may have a second crystal structure comprising at least one of an orthorhombic structure, a hexagonal structure, or a perovskite-like structure, and 1-x-y may be greater than about 0.15.
(FR) L'invention concerne des compositions comprenant une pérovskite et une non-pérovskite. Les perovskites comprennent AxA'yA''(1-x-y)BX3, et les non-perovskites peuvent comprendre A", B et X, A étant un premier cation, A' étant un deuxième cation, A" étant un troisième cation, B étant un quatrième cation, X étant un anion. Dans certains cas, A, A' et A'' sont individuellement indépendamment (NH2)2CH+, CH3NH3 +, Cs+, Rb+, ou (NH2)2(C=NH2)+, à condition que A, A' et A'' soient individuellement différents. La pérovskite peut avoir une première structure cristalline dans laquelle l'anion est partagé en coin, la non-pérovskite peut avoir une seconde structure cristalline comprenant au moins une structure parmi une structure orthorhombique, une structure hexagonale, ou une structure de type pérovskite, et 1-x-y peut être supérieur à environ 0,15.
