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.

Fast heat treatment method for a complete all-solid-state electrochromic stack

A process for obtaining an item including a substrate made of glass or glass ceramic coated on at least one portion of at least one of its faces with a stack of thin-layers including no silver layers and including at least one thin layer of a transparent electrically conductive oxide, the process including: a step of depositing the stack, in which step the thin layer of a transparent electrically conductive oxide and at least one thin homogenizing layer are deposited, the thin homogenizing layer being a metal layer or a layer based on a metal nitride other than aluminum nitride, or a layer based on metal carbide; then a heat treatment step in which the stack is exposed to radiation.

Method for producing a substrate coated with a stack including a conductive transparent oxide film

A process for activating a layer supported by a glass substrate includes carrying out a heat treatment in a chamber of a stack of several examples of the glass substrate, the glass substrates being separated by an interlayer powder. The layer to be activated may be an ITO layer, or a titanium oxide layer, or an SiOlayer, or a silver layer.

The invention relates to an electrochemical device () having electrically controllable optical and/or energy transmission properties comprising a substrate (), a functional system () formed on the substrate and a cover film () formed on the functional system. The functional system comprises a bottom electrode coating (), formed on the substrate, a top electrode coating () and at least one electrochemically active film () located between the two electrode coatings, the electro-chemically active film being able to switch reversibly between a first state and a second state having optical and/or energy transmission properties different from the first state. The cover film defines at least one surface cavity () that passes through the cover film without penetrating the top electrode coating and the device comprises electrical connection means () arranged at least partially in at least one surface cavity for electrical contact with the top electrode coating.
