Abstract: Busbars with electrically conductive covers are implemented for an electroactive device. Different transparent conductive layers may surround an electroactive layer that is between the transparent conductive layers of the electroactive devices. The busbars may include an electrically conductive adhesive tape that includes an adhesion layer, a conductor track, and cover that is electrically conductive toward the conductor track, capable of being soldered or adhered to a conductor, opaque, and satisfy a visibility requirement that obscures the busbar from an environment external to the electroactive device and that is connective using the adhesive layer to one of the transparent conductive layers.

Abstract: A conductor for an insulated glazing unit (IGU) is described. The IGU may have two or more panes. The two or more panes may run parallel to one another. The IGU May have one or more seals that form a glazing interior space with the first pane and the second pane. The glazing interior space may include one or more recipient devices and multiple busbars. Each of the busbars may be coupled to at least one of the one or more recipient devices. The conductor may include multiple conducting elements that are respectively electrically connected to different ones of the busbars providing power and/or control signals received from a controller for the one or more recipient devices. The conductor may penetrate at least one of the one or more seals at a location where at least two of the busbars are available for connection.

The electrochromic apparatus can further include a first voltage supply terminal that is offset from a center of the first bus bar.

Abstract: A method implemented by a system for manufacturing a device having a coated transparent substrate is provided. The method includes providing the device having a transparent substrate. The method also includes coating the transparent substrate with a first transparent conductive oxide (TCO) layer in accordance with one or more parameters. The coating the transparent substrate comprises performing a physical deposition process on the transparent substrate. The method further includes determining a resistance across the first TCO layer. In addition, the method includes determining whether the resistance across the first TCO layer is within a resistance range. The method also includes in response to determining that the resistance across the first TCO layer is within the resistance range, coating the device with a second TCO layer in accordance with the one or more parameters to provide a resistance across the second TCO layer that is within the resistance range.

Abstract: When transitioning an electrochromic (EC) device between two tint levels, a control unit may repeatedly adjust an applied voltage based on a stack voltage of the EC device. The stack voltage of the EC device may be measured and compared to a reference or target stack voltage. The stack voltage may be measured in any of various methods, such as by measuring it directly, via a measured equivalent series resistance, or via an open circuit voltage measurement. The applied voltage may then be changed or adjusted based on the measured stack voltage and the comparison of the stack voltage to the reference value. This process may be repeated multiple times and may essentially be performed continually until the stack voltage attains the desired level or at least attains a level within a predetermine threshold of the desired level.
