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 tantalum oxide (NiWTaO). This material is particularly beneficial in that it is very transparent in its clear state.
Claims20
An integrated deposition system for fabricating an electrochromic stack, the system comprising:
- a plurality of deposition stations aligned in series and interconnected and operable to pass a substrate from one station to the next without exposing the substrate to an external environment, wherein the plurality of deposition stations comprise
- (i) a first deposition station containing one or more material sources for depositing a cathodically coloring layer;
- (ii) a second deposition station containing one or more material sources for depositing an anodically coloring layer comprising nickel tungsten tantalum oxide;
- and
- a controller containing program instructions for passing the substrate through the plurality of stations in a manner that deposits on the substrate (i) the cathodically coloring layer, and (ii) the anodically coloring layer to form a stack comprising at least the cathodically coloring layer and the anodically coloring layer.
