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-niobium-oxide (NiWNbO). This material is particularly beneficial in that it is very transparent in its clear state.
Claims20
An electrochromic device stack comprising:
- a substrate,
- a cathodically coloring layer comprising a cathodically coloring material;
- and
- an anodically coloring layer comprising a first anodically coloring layer and a second anodically coloring layer,
- wherein the cathodically coloring layer is in contact with the first anodically coloring layer,
- wherein the first anodically coloring layer comprising a first anodically coloring material comprises nickel tungsten oxide, and the second anodically coloring layer comprising a second anodically coloring material comprises nickel tungsten niobium oxide.
