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-tin-oxide (NiWSnO). This material is particularly beneficial in that it is very transparent in its clear state.
