Embodiment Construction

[0045] figure 1 Represented in is an electrochromic device with controlled transparency according to the invention, which is particularly intended for application in the production of automotive glazing units for which it is desirable to be able to adjust the transparency and control the curvature.

[0046] Typically, such devices are formed by functional layer stacks known as "all solid state" stacks, the structure of which includes an electrochromic function of the type EC1 / EL1 / EL2 / EC2 between the conductive layers TC1 and TC2 system, the functional layer stack is located between the carrier substrate 1a and the opposite substrate 1b. In such a device:

[0047] - The two outermost layers TC1 and TC2 of the stack are metal or made of In 2 o 3 :Sn(ITO), SnO 2 : TCO (transparent conductive oxide) type conductive layer made of F, ZnO:Al. They can also be layers of the TCO / metal / TCO type, the metal being chosen especially from silver, gold, platinum, copper, or layers of the...

Abstract

The invention relates to an electrochromic device with controlled transparency, in particular of the electrically controlled type, that comprises a transparent bearing substrate (1a) and a counter-substrate (1b), at least one stack (3, 3') of functional layers in which the end layers (TC1, TC2; TC1', TC1') include electrically conducting layers, the conductivity of at least one electrically conducting layer (TC2,TC2') not in contact with the bearing substrate (1a) being reinforced by an array of conducting members (8) in contact therewith, characterised in that the array includes a meshing (6, 6') in which the surface area of the inter-mesh free space (9) substantially ranges from 0.04 mm2 to 0.16 mm2 and is preferably about 0.09 mm2.

Description

technical field [0001] The present invention relates to an electrochromic device with controlled transparency, in particular intended to constitute an electrically controllable glazing unit. Background technique [0002] Glass units are known to have light transmission capabilities that can be adjusted from a good level of transparency to almost complete opacity. Such glass units have found application in various technical fields. [0003] It is thus possible to use them as glazing units for dwellings, eg to regulate the degree of sunlight exposure of a place depending on the outside conditions and user needs. It is also possible to use them as insulating shutters to protect the privacy of the occupants of a place with respect to the outside or adjacent rooms. [0004] It is also possible to use such devices in the automotive field, for example to control the level of transparency of a car's windshield and / or side windows or sunroof, and also on certain accessories of a ca...
