Patent number: 11440838Abstract: 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.

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: April 27, 2020Date of Patent: September 13, 2022Assignee: View, Inc.Inventors: Anshu A.
