Abstract: Various embodiments herein relate to power distribution networks for optically switchable windows. In some embodiments, a system for monitoring and maintaining a power distribution network of optically switchable windows of a site is provided. The system includes a control panel monitor which is configured to determine a control panel voltage and current at a terminal of a control panel. The system further includes sense circuitry which is configured to determine a first window controller voltage and current for a first window controller of a plurality of window controllers. The system further includes one or more controllers which are configured to generate voltage network data based on a combination of the control panel voltage and current and the first window controller voltage and current. The system then determines an error condition in the power distribution network based on the voltage network data.

Abstract: Various embodiments herein relate to power distribution networks for optically switchable windows. A number of different topologies are provided. In many embodiments, a control panel may be connected with a trunk line, which is connected to a plurality of optically switchable windows. The plurality of optically switchable windows may be powered by the shared trunk line. This topology provides substantial improvements over topologies in which each optically switchable window is connected to the control panel via separate, individual lines. Further, certain embodiments herein relate to installation kits for installing power distribution networks for optically switchable windows.

Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.

Abstract: “Smart” controllers for windows having controllable optical transitions are described. Controllers with multiple features can sense and adapt to local environmental conditions. Controllers described herein can be integrated with a building management system (BMS) to greatly enhance the BMS's effectiveness at managing local environments in a building. The controllers may have one, two, three or more functions such as powering a smart window, determining the percent transmittance, size, and/or temperature of a smart window, providing wireless communication between the controller and a separate communication node, etc.

Abstract: Methods are provided for fabricating electrochromic devices that mitigate formation of short circuits under a top bus bar without predetermining where top bus bars will be applied on the device. Devices fabricated using such methods may be deactivated under the top bus bar, or may include active material under the top bus bar. Methods of fabricating devices with active material under a top bus bar include depositing a modified top bus bar, fabricating self-healing layers in the electrochromic device, and modifying a top transparent conductive layer of the device prior to applying bus bars.

Abstract: Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.

Abstract: Described are methods of fabricating lithium sputter targets, lithium sputter targets, associated handling apparatus, and sputter methods including lithium targets. Various embodiments address adhesion of the lithium metal target to a support structure, avoiding and/or removing passivating coatings formed on the lithium target, uniformity of the lithium target as well as efficient cooling of lithium during sputtering. Target configurations used to compensate for non-uniformities in sputter plasma are described. Modular format lithium tiles and methods of fabrication are described. Rotary lithium sputter targets are also described.

Abstract: This disclosure relates generally to optically-switchable devices, and more particularly, to systems, apparatus, and methods for controlling optically-switchable devices. In some implementations, an apparatus for controlling one or more optically-switchable devices includes a processing unit, a voltage regulator and a polarity switch. The processing unit can generate: a command voltage signal based on a target optical state of an optically-switchable device, and a polarity control signal. The voltage regulator can receive power at a first voltage and increase or decrease a magnitude of the first voltage based on the command voltage signal to provide a DC voltage signal at a regulated voltage. A polarity switch can receive the DC voltage signal at the regulated voltage to maintain or reverse a polarity of the DC voltage signal based on the polarity control signal. The polarity switch can output the DC voltage signal at the regulated voltage and at the polarity based on the polarity control signal to power the optically-switchable device. In some other implementations, the apparatus includes a processing unit, an energy storage device, and first and second voltage regulators.
