Patent number: 11960189Abstract: This disclosure provides spacers for smart windows. In one aspect, a window assembly includes a first substantially transparent substrate having an optically switchable device on a surface of the first substrate. The optically switchable device includes electrodes. A first electrode of the electrodes has a length about the length of a side of the optically switchable device. The window assembly further includes a second substantially transparent substrate a metal spacer between the first and the second substrates. The metal spacer has a substantially rectangular cross section, with one side of the metal spacer including a recess configured to accommodate the length of the first electrode such that there is no contact between the first electrode and the metal spacer. A primary seal material bonds the first substrate to the metal spacer and bonds the second substrate to the metal spacer.Type: GrantFiled: March 28, 2022Date of Patent: April 16, 2024Assignee: View, Inc.Inventors: Yashraj Bhatnagar, Trevor Frank, Fabian Strong, Sridhar Karthik Kailasam, Robert Babcock, Ronald M.

Patent number: 11559970Abstract: Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.Type: GrantFiled: August 19, 2020Date of Patent: January 24, 2023Assignee: View, Inc.Inventors: Fabian Strong, Yashraj Bhatnagar, Abhishek Anant Dixit, Todd Martin, Robert T.

Publication number: 20220032584Abstract: Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.Type: ApplicationFiled: June 11, 2021Publication date: February 3, 2022Applicant: View, Inc.Inventors: Ronald M.

Publication number: 20210347684Abstract: Transparent conductive coatings are polished using particle slurries in combination with mechanical shearing force, such as a polishing pad. Substrates having transparent conductive coatings that are too rough and/or have too much haze, such that the substrate would not produce a suitable optical device, are polished using methods described herein. The substrate may be tempered prior to, or after, polishing. The polished substrates have low haze and sufficient smoothness to make high-quality optical devices.Type: ApplicationFiled: July 23, 2021Publication date: November 11, 2021Inventors: Yashraj Bhatnagar, Robert T.

Publication number: 20210215990Abstract: This disclosure describes insulated glass units (IGUs) that incorporate electrochromic devices. More specifically, this disclosure focuses on different configurations available for providing an electrical connection to the interior region of an IGU. In many cases, an IGU includes two panes separated by a spacer. The spacer defines an interior region of the IGU and an exterior region of the IGU. Often, the electrochromic device positioned on the pane does not extend past the spacer, and some electrical connection must be provided to supply power from the exterior of the IGU to the electrochromic device on the interior of the IGU. In some embodiments, the spacer includes one or more holes (e.g, channels, mouse holes, other holes, etc.) through which an electrical connection (e.g., wires, busbar leads, etc.) may pass to provide power to the electrochromic device.Type: ApplicationFiled: November 20, 2020Publication date: July 15, 2021Applicant: View, Inc.Inventors: Ronald M. Parker, Yashraj Bhatnagar, Trevor Frank, Travis D. Wilbur, Stephen C. Brown
