Abstract: An electrochromic apparatus is disclosed. The electrochromic device can include a first bus bar electrically connected to a first transparent conductor, where the first bus bar comprises a first segment between a second segment and a third segment, where the first segment has a first thickness that is less than a second thickness of the second segment and less than a third thickness of the third segment. 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.
