Abstract: An electrochromic device and method of cloaking an electrochromic device is disclosed. The electrochromic device can include a first transparent conductive layer on a substrate, a second transparent conductive layer, a cathodic electrochromic layer between the first transparent conductive layer and the second transparent conductive layer, and an anodic electrochromic layer between the first transparent conductive layer and the second transparent conductive layer. The stack of layers can be patterned to be parallel to a voltage gradient of the electrochromic device and extend through all layers of the electrochromic device. The electrochromic device can also include a masking layer that covers the patterned inactive area. A method can include determining a pattern of inactive areas within a visible area, determining a cloaking pattern that corresponds to the pattern of inactive areas, and depositing a masking layer in the areas of the cloaking pattern.

Abstract: An apparatus including a substrate with at least three sides and an active stack on the substrate. The active stack can include a first transparent conductive layer, a second transparent conductive layer, an anodic electrochemical layer, and a cathodic electrochemical layer. The apparatus can also include a first bus bar set comprising a plurality of bus bars, wherein each bus bar of the first bus bar set is electrically coupled to the first transparent conductive layer, a second bus bar set comprising a plurality of bus bars, wherein each bus bar of the second bus bar set is electrically coupled to the second transparent conductive layer, and a bus bar arrangement wherein the bus bar arrangement comprises a bus bar from the first bus bar set and a bus bar from the second bus bar set on at least three sides of the substrate.
