    Abstract: Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition. In certain embodiments, the device includes a counter electrode having an anodically coloring electrochromic material in combination with an additive.

    Abstract: Certain aspects pertain to a cloud detector comprising a first detector module directed to a first region of the sky and a second detector module directed to a second region of the sky. Each detector module has a tube enclosing one or more sensing elements. The one or more sensing elements of the first detector module are configured to take weather condition readings from the first region of the sky. The one or more sensing elements of the second detector module are configured to take weather condition readings from the second region of the sky. In one aspect, the cloud detector is configured to detect cloud cover based on these weather condition readings. In some cases, the one or more sensing elements comprise an infrared radiation detector (e.g., thermopile) for measuring infrared radiation intensity and a photosensor element for measuring sunlight intensity.

    Abstract: Various embodiments herein relate to methods, structures, tools, installation systems, etc. for retrofitting a new electrochromic window in a pre-existing window recess. In many cases, the new electrochromic window is installed parallel to a lite of a pre-existing window, with the resulting structure including the new electrochromic window, the pre-existing window, and a pocket that forms between them. Installation of a new electrochromic window in tandem with a pre-existing window results in many benefits including improved insulation (e.g., due to the presence of the additional air pocket(s) and lite(s)), improved climate control (e.g., due to the ability to control the amount of sunlight entering the building via the electrochromic window), and enhanced aesthetics.

    Abstract: Methods are described for the commissioning of optically switchable window networks. During commissioning, network addresses are paired with the locations of installed devices for components on a window network. Commissioning may also involve steps of testing and validating the network devices. By correctly pairing the location of a device with its network address, a window network is configured to function such that controls sent over the network reach their targeted device(s) which in turn respond accordingly. The methods described herein may reduce frustrations that result from mispairing and installation issues that are common to conventional commissioning practices. Commissioning may involve recording a response to a manually or automatically initiated trigger. Commissioning methods described herein may rely on user input, or be automatic, not requiring user input.

    Abstract: This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

    Abstract: Electrochromic devices and methods may employ the addition of a defect-mitigating insulating layer which prevents electronically conducting layers and/or electrochromically active layers from contacting layers of the opposite polarity and creating a short circuit in regions where defects form. In some embodiments, an encapsulating layer is provided to encapsulate particles and prevent them from ejecting from the device stack and risking a short circuit when subsequent layers are deposited. The insulating layer may have an electronic resistivity of between about 1 and 108 Ohm-cm. In some embodiments, the insulating layer contains one or more of the following metal oxides: aluminum oxide, zinc oxide, tin oxide, silicon aluminum oxide, cerium oxide, tungsten oxide, nickel tungsten oxide, and oxidized indium tin oxide. Carbides, nitrides, oxynitrides, and oxycarbides may also be used.
