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.
