Abstract: Conventional electrochromic devices frequently suffer from poor reliability and poor performance. Improvements are made using entirely solid and inorganic materials. Electrochromic devices are fabricated by forming an ion conducting electronically-insulating interfacial region that serves as an IC layer. In some methods, the interfacial region is formed after formation of an electrochromic and a counter electrode layer. The interfacial region contains an ion conducting electronically-insulating material along with components of the electrochromic and/or the counter electrode layer. Materials and microstructure of the electrochromic devices provide improvements in performance and reliability over conventional devices.

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: Aspects of this disclosure concern controllers and control methods for applying a drive voltage to bus bars of optically switchable devices such as electrochromic devices. Such devices are often provided on windows such as architectural glass. In certain embodiments, the applied drive voltage is controlled in a manner that efficiently drives an optical transition over the entire surface of the electrochromic device. The drive voltage is controlled to account for differences in effective voltage experienced in regions between the bus bars and regions proximate the bus bars. Regions near the bus bars experience the highest effective voltage.

Abstract: A method for lithiating an electrochromic device comprise forming a first transparent conductive layer on a substrate, forming an electrochromic structure on the first transparent conductive layer, forming a second transparent conductive layer on the electrochromic structure, and lithiating the electrochromic structure through the second transparent conductive layer. In one exemplary embodiment lithiating the electrochromic structure comprises lithiating the electrochromic structure at a temperature range of between about room temperature and about 500 C for the duration of the lithiation process. In another exemplary embodiment, lithiating the electrochromic structure further comprises lithiating the electrochromic structure by using at least one of sputtering, evaporation, laser ablation and exposure to a lithium salt. The electrochromic device can be configured in either a “forward” or a “reverse” stack configuration.

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.

Abstract: A plumbing system for a shower or the like includes a mixing valve operable for delivering a water flow of adjustable temperature from a water source to a dispensing device downstream from the mixing valve. The system further includes a diverter valve between the mixing valve and the dispensing device, and operable to divert a selectively variable portion of the water from the mixing valve back to the water source. A thermochromic thermal indicator, downstream from the mixing valve, may advantageously provide a visible indication of the water flow having achieved a predetermined temperature. The thermal indicator may be a thermochromic PVC conduit, or it may be a fitting having an inlet, an outlet, a thermochromic PVC element therebetween, and a barrier located between the inlet and the outlet so as to define a flow path that includes an interior surface of the thermochromic element.

Abstract: The embodiments herein relate to electrochromic stacks, electrochromic devices, and methods and apparatus for making such stacks and devices. In various embodiments, an anodically coloring layer in an electrochromic stack or device is fabricated to include nickel-tungsten-tin-oxide (NiWSnO). This material is particularly beneficial in that it is very transparent in its clear state.
