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.

Abstract: This disclose describes systems, methods and non-transitory computer readable media for controlling operations of an EC device with compensation for the hysteresis effect of the leakage current. A control module, coupled to the EC device, may be configured to develop a hysteresis model representing a hysteresis effect of a leakage current of the EC device, track one or more prior operating histories of the EC device, and transition the EC device to a target transmission level with compensation for the hysteresis effect of the leakage current based in part on a current transmission level, the one or more prior operating histories, and the hysteresis model of the EC device.

Abstract: A non-light-emitting variable transmission device can include an active stack; a transparent conductive layer overlying the active stack; an antireflective layer overlying the transparent conductive layer and defining a hole; and a bus bar comprising a conductive tape that extends into the hole and contacts the transparent conductive layer. Proper selection of materials and design of a bus bar can allow an electrical connection to be made to the transparent conductive layer without the need to cut an underlying transparent conductive layer. A method of forming the non-light-emitting variable transmission device can include patterning the antireflective layer to define the hole that extends to the transparent conductive layer. Improved control in patterning allows the antireflective layer to be relatively thin and not remove too much of the underlying transparent conductive layer.
