摘要
An all-solid electrochromic device with controlled infrared reflection or emission, in particular of electro-controllable type, comprising a stack successively comprising from a back face (3) as far as a front face (1) exposed to infrared radiation (2): a substrate (4) made of an electron-conducting material, or a substrate made of a non-electron-conducting material coated with a layer made of an electron-conducting material, forming a first electrode; a layer made of a first proton storage electrochromic material (5); a layer of a proton-conducting and electron-insulating electrolyte (6); a bilayer comprising a layer of a non-electrochromic, sub-stoichiometric tungsten oxide WO3-y forming a second electrode; said tungsten oxide WO3-y layer being arranged underneath a layer with variable infrared reflection of a second electrochromic material with variable proton intercalation rate, chosen from among crystallized tungsten oxide HxWO3-c and hydrated crystallized tungsten oxide HxWO3.nH20-c; a protective layer (10) transparent to infrared radiation. Bilayer for this device. Method for preparing this device.
