Patent number: 11891327Abstract: 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.Type: GrantFiled: July 29, 2022Date of Patent: February 6, 2024Assignee: View, Inc.Inventors: Anshu A.

Publication number: 20230324754Abstract: 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: ApplicationFiled: June 7, 2023Publication date: October 12, 2023Applicant: View, Inc.Inventors: Robert Tad Rozbicki, Sridhar Karthik Kailasam, Robin Sean Friedman, Dane Thomas Gillaspie, Anshu Ajit Pradhan, Disha Mehtani

Publication number: 20230314893Abstract: 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.Type: ApplicationFiled: May 23, 2023Publication date: October 5, 2023Inventors: Sridhar Karthik Kailasam, Dhairya Shrivastava, Zhiwei Cai, Robert Tad Rozbicki, Dane Thomas Gillaspie, Todd William Martin, Anshu Ajit Pradhan, Ronald M.
