摘要

Process and cooling device induced by an external stimulus on an organic-inorganic caloric hybrid material. Cooling process induced by an external stimulus that involves applying an external stimulus selected between hydrostatic pressure, uniaxial pressure, electric field and illumination with light, to an organic-inorganic hybrid material of crystal structure with hexagonal packing, of formula ABX3 (I), where: A is a particular monovalent organic cation or a certain mixture of monovalent organic cations or a certain mixture of monovalent organic cations and monovalent inorganic cations, B is a particular divalent metal cation, a certain mixture of divalent metal cations, or a certain 50/50 atomic mixture of a monovalent cation and a trivalent cation, and X is a halide anion or a mixture thereof. Device with refrigeration capacity induced by an external stimulus, comprising the previous organic-inorganic hybrid material, as well as hybrid organic-inorganic material of formula [(CH3)2 NH2 ] PbCI3 (Ia) and its preparation procedure.
