Electrochromic window.

摘要

The subject of the invention is an electrochromic system which includes a transparent electrically conducting layer (2), a layer (3) of a cathodic electrochromic material capable of reversibly inserting M<+> cations of the H<+> or Li<+> type, a layer (5) of electrolyte, a layer (7) of a counterelectrode made from an anodic electrochromic material and a second electrically conducting layer (8), a barrier layer (6) being interposed between the electrolyte (5) and the counterelectrode (7), the said barrier being open to the diffusion of the M<+> cations.
