Abstract:
1. An electrochromic device having controlled transmission or reflection of at least one electrically controllable active area (CDEF), comprising, on a carrier substrate, a multilayer stack comprising at least, in succession; a layer forming a lower electrically conductive electrode; various functional layers, at least one of which is an electrochromic layer, and at least one of these layers being electrically insulating; and an upper electrically conductive electrode, in which device: at least one total partition extends from the electrically insulating layer without passing through it, and passes through the layer(s) separating the insulating layer from the substrate, the total partition dividing a surface of the lower electrode into two regions electrically isolated from each other, namely a free region, in line with which the upper electrode is soldered to a first current-supply connector, and an active region containing the active area (CDEF); and at least one selective partition passes through the upper electrode and the various layers separating the upper electrode from the lower electrode, the selective partition dividing a surface of the upper electrode into two regions electrically isolated from each other, namely a free region that receives a second current-supply connector which is soldered to the lower electrode, and an active region containing the active area (CDEF), wherein the free region of the lower electrode is soldered to the current-supply connector of the upper electrode.
