Embodiment Construction

[0053] Figures 1a-5c Shown in is the basic stages of a first example of a process according to the invention for the manufacture of a controlled-transmission electrochromic device 1 intended especially for the manufacture of glasses whose transparency it is desired to be able to adjust.

[0054] In the first step of the process according to the invention, as Figure 1a and Figure 1b As shown in , the conductive layer intended to form the underlying electrode 4 is deposited onto a carrier substrate 3 , which in the present mode of realization consists of a glass support. The deposition is performed in particular by conventional sputtering processes. In known manner, this electrode can be of metallic type, or be made of In 2 o 3 :Sn (ITO), SnO 2 :F or transparent conductive oxide (TCO) types made of ZnO:Al. Possibly, it can also be a multilayer of the TCO / metal / TCO type, the metal being chosen especially from silver, gold, platinum and copper, or a NiCr / metal / NiCr type, t...

Abstract

The present invention relates to an electrochromic device comprising: at least one margining (5), called selective margening, separating the surface of the top electrode (9) into two zones isolated from each other, namely a free zone (9a) and an active zone (9b); at least one margining (12), called total margining, separating the surface of the bottom electrode (4) into two zones electrically isolated from each other, namely a free zone (4a) and an active zone (4b); at least one free zone (9a) of the top electrode (9) receives a first current lead connector (15) connected by soldering to the active zone (4b) of the bottom electrode (4); the active surface (9b) of the top electrode (9) is in electrical contact with connection means (20, 21a) which are connected to a second current lead connector (21) electrically isolated from the free zone (9a).

Description

technical field [0001] The present invention relates to an electrochromic device of controlled transparency, in particular a device designed for use in electrically controllable glasses, and to a process for manufacturing said device. The invention also relates to an electrochromic glass provided with such a device and to the use of this glass in various applications. Background technique [0002] Glasses which can be adjusted from a good transparency level to the most opaque are known which have light transmission capabilities. This glass has been used in various technical fields. [0003] Thus, the glass can be used as a window for a dwelling to regulate, for example, the amount of sunlight entering the room according to external conditions and the wishes of the user. The glass can also be used to divide screens to protect the privacy of the occupants of a room from the outside or from the next room. [0004] Such devices can also be used, for example, in the automotive...
