  • Solid state thermochromic device, and method for producing said device
    Patent number: 11086054
    Abstract: A solid-state thermochromic device and method for producing the device, the device including: a stack successively including, from a rear face to a front face exposed to solar radiation: a) a solid substrate of an inorganic material resistant up to a temperature of 550° C.; b) an infrared-reflective layer of an electronically conductive material; c) electronically insulating interface layers; d) an electronically insulating inorganic dielectric layer transparent to infrared radiation, of cerium oxide CeO2, with a thickness between 400 and 900 nm; e) electronically insulating interface layers; f) a layer of an infrared-active thermochromic material, an n-doped VO2 vanadium oxide, and crystallized in a monoclinic or rutile phase, with a thickness between 30 and 50 nm; and g) a solar-protective coating, transparent to infrared radiation.
    Type: Grant
    Filed: July 26, 2017
