Title
(EN) COLOR-STABILIZED ELECTROCHROMIC DEVICES

Abstract
(EN)
An electrochromic device having; (a) at least one substantially transparent substrate (112,114) having an electrically conductive material (118,120) associated therewith; and (b) an electrochromic medium having a predetermined color while in a high transmission state, wherein the electrochromic medium (124) having; (1) an anodic material and a cathodic material, wherein both of the anodic and cathodic materials are electroactive and at least one of the anodic and cathodic material is electrochromic; (2) a redox buffer; and (3) means associated with the redox buffer for controllably maintaining the predetermined color of the electrochromic medium while in the high transmission state relative to an electrochromic medium without the redox buffer.
(FR)
L'invention se rapporte à un dispositif électrochromique comportant (a) au moins un substrat sensiblement transparent (112, 114) associé à une matière électriquement conductrice (18, 120); et (b) un support électrochromique ayant une couleur préétablie dans un état de transmission élevé. Ledit support électrochromique (124) comporte: (1) une matière anodique et une matière cathodique, les matières anodique et cathodique étant toutes deux électroactives et l'une au moins de ces matières anodique et cathodique étant électrochromique; (2) un tampon redox et (3) un moyen associé au tampon redox et conçu pour maintenir de manière régulée la couleur préétablie du support électrochromique lorsque celui-ci se trouve dans l'état de transmission élevé par rapport à un support électrochromique sans le tampon redox.
