Abstract (en)
[origin: WO2020109725A1] The present invention relates to a method for manufacturing an electrochromic glazing, said glazing having an electrochromic stack comprising: a first transparent conductive layer (TCO1), a layer of an electrochromic material (EC), a layer of an ionic conductive electrolyte (CI), a counter electrode layer (CE), a second transparent conductive layer (TCO2), said method comprising the following steps: providing a first glass panel (2) and a second glass panel (2); depositing a first transparent conductive layer (TCO1) on the first glass panel and a second transparent conductive layer (TCO2) on the second glass panel; depositing a layer of a material (EC) on the first transparent conductive layer (TCO1) and a counter electrode layer (CE) on the second transparent conductive layer (TCO2); depositing the layer of an ionic conductive electrolyte (CI) on either of the layers of an electrochromic material (EC) or counter electrode (CE); assembling the two glass panels to form a laminated glazing. The invention is characterized in that it further comprises at least one heat treatment step consisting in thermally treating at least one transparent conductive layer (TCO1, TCO2) of a glass panel by a rapid thermal treatment device before assembling the glass panels.
