Patent number: 11668990Abstract: 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.Type: GrantFiled: August 14, 2020Date of Patent: June 6, 2023Assignee: View, Inc.Inventors: Robert T.

Patent number: 11668992Abstract: 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.Type: GrantFiled: March 24, 2021Date of Patent: June 6, 2023Assignee: View, Inc.Inventors: Dhairya Shrivastava, Stephen Clark Brown

Patent number: 11630367Abstract: Controllers and control methods apply a drive voltage to bus bars of a thin film optically switchable device. The applied drive voltage is provided at a level that drives a transition over the entire surface of the optically switchable device but does not damage or degrade the device. This applied voltage produces an effective voltage at all locations on the face of the device that is within a bracketed range. The upper bound of this range is associated with a voltage safely below the level at which the device may experience damage or degradation impacting its performance in the short term or the long term. At the lower boundary of this range is an effective voltage at which the transition between optical states of the device occurs relatively rapidly. The level of voltage applied between the bus bars is significantly greater than the maximum value of the effective voltage within the bracketed range.Type: GrantFiled: December 23, 2020Date of Patent: April 18, 2023Assignee: View, Inc.Inventors: Anshu A.

Patent number: 11592722Abstract: 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. In various embodiments, a counter electrode is fabricated to include a base anodically coloring material and one or more additives.Type: GrantFiled: February 5, 2020Date of Patent: February 28, 2023Assignee: View, Inc.Inventors: Zhongchun Wang, Anshu A.
