Patent ID: 8411348

Claim:
An electrochemical/electrically controllable device having variable optical and/or energy properties comprising at least one carrier substrate, at least one electroactive layer, at least one lower electrode, and at least one upper electrode, wherein the at least one electroactive layer is between the lower electrode and the upper electrode, wherein the lower electrode and/or the upper electrodes comprises at least one electroconductive layer comprising a metal grid that consists of a pure metal which is coated with at least one electrochemical protection layer, wherein the electrochemical protection layer is based on a material selected from group consisting of titanium, gold, platinum and palladium, said material optionally being nitrided, the electrochemical protection layer being combined with at least one barrier layer based on a metal oxide, wherein the metal oxide is selected from the group consisting of zinc oxide, zinc oxide doped with another metal selected from the family of the following metals: Al, Ga, B, and Sc, tin-doped indium oxide and antimony-doped tin oxide.
