A process for manufacturing an electrochromic glazing unit includes forming, on one face of a glass sheet, a complete all-solid-state electrochromic stack including in succession a first layer of a transparent conductive oxide; a layer of a cathodically colored mineral electrochromic material to form an electrochromic electrode; a layer of an ionically conductive mineral solid electrolyte; a layer of a cation intercalation material to form a counter electrode; and a second layer of a transparent conductive oxide; then heat treatment of the complete electrochromic stack by irradiation with radiation having a wavelength comprised between 500 and 2000 nm, the radiation originating from a radiating device placed facing the electrochromic stack, a relative movement being created between the radiating device and the substrate so as to raise the electrochromic stack to a temperature at least equal to 300&#xb0; C. for a brief duration, for example shorter than 100 milliseconds.

Electrically conducting support for an electrochromic device, electrochromic device incorporating it, and its manufacture

An electrically controllable device includes two supported electrodes, each coated with a conductive coating, the two electrodes positioned with respect to one another so that the conductive coatings are facing each other. An electroactive system, sandwiched between, and in contact with, the two electrodes, has an area smaller than that of each of the electrodes to define a peripheral groove over the entire perimeter of the electroactive system. A peripheral seal fills the groove over the entire perimeter of the electroactive system and is entirely in contact with the two electrodes. The contact area between the seal and the first electrode and the contact area between the seal and the second electrode each include a conductive part and a non-conductive part. No conductive part of the contact area between the seal and the first electrode is opposite a conductive part of the contact area between the seal and the second electrode.
