Abstract

An electrochemical device and method of forming said device is disclosed. The method can include providing a substrate and stack overlying the substrate. The stack can include a first transparent conductive layer over the substrate, a cathodic electrochemical layer over the first transparent conductive layer, an anodic electrochemical layer over the electrochromic layer, and a second transparent conductive layer overlying the anodic electrochemical layer. The method can include depositing an insulating layer over the stack and determining a first pattern for the second transparent conductive layer. The first pattern can include a first region and a second region. The first region and the second region can be the same material. The method can include patterning the first region of the second transparent conductive layer without removing the material from the first region. The first region can have a first resistivity and the second region can have a second resistivity.
