Electrochromic multi-layer devices with composite electrically conductive layers

A method for the preparation of a multi-layer device, comprising:

• forming a first composite electrically conductive layer arranged against a first substrate;
• forming a first electrode layer in electrical contact with the first composite electrically conductive layer;
• forming a second composite electrically conductive layer on a second substrate;
• forming a second electrode layer in electrical contact with the second composite electrically conductive layer;
• and
• forming a multi-layer device comprising the first composite electrically conductive layer, first electrode layer, the second electrode layer, and the second composite electrically conductive layer;
• wherein:
• the first composite electrically conductive layer comprises:
• a first conductive layer;
• a first transparent conductive material layer;
• and
• resistance to current flow substantially parallel to a major surface of the first composite electrically conductive layer that varies as a function of position;
• wherein the first conductive layer, the first transparent conductive material layer, or both the first conductive layer and the first transparent conductive material layer further comprises one or more of a composition that varies as a function of position, a thickness that varies as a function of position, or a defect density that varies as a function of position;
• and
• the second composite electrically conductive layer comprises:
• a second conductive layer;
• a second transparent conductive material layer;
• and
• a resistance to current flow substantially parallel to a major surface of the second composite electrically conductive layer that varies as a function of position;
• and
• and wherein the first and second electrode layers comprise electrochromic materials.
