Electrochromic glazing with series connected cells, and production method therefor

摘要

An electrochromic glazing containing: a substrate including a layer structure thereon, which contains a first and second electrode layer, between which a first and second electrochemically active layer are situated, which each reversibly incorporate ions, wherein the first active layer contains an electrochromic material and the two active layers are separated from each other by an electrolyte layer, the layer structure being subdivided into series-connected electrochromic cells by a transition zone comprising: a first trench; a second trench; and a third trench between the first and second trenches, wherein the first and second trenches subdivide the first and second electrode layers into first electrode sections electrically insulated from each other and second electrode sections electrically insulated from each other, respectively, and the third trench is filled with an electrically conductive material, by which the first and second electrode sections of the cells adjacent the transition zone are electrically connected.

1. An electrochromic glazing, comprising:
a substrate; and a layer structure disposed on the substrate, wherein the layer structure comprises at least a first electrode layer and a second electrode layer, between which a first electrochemically active layer and a second electrochemically active layer are situated, which each reversibly incorporate ions, wherein the first active layer comprises an electrochromic material, and wherein the first and second active layers are separated from each other by an electrolyte layer, wherein the layer structure is subdivided into series-connected electrochromic cells by one or a plurality of transition zones, each transition zone comprising: a first trench, by which the first electrode layer is subdivided into first electrode sections electrically insulated from each other; a second trench, by which the second electrode layer is subdivided into second electrode sections electrically insulated from each other; and a third trench filled with an electrically conductive material, by which the first electrode section and the second electrode section of the electrochromic cells adjacent the transition zone are electrically connected to each other, wherein the third trench is arranged between the first trench and the second trench.
