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 a heterogeneous structure, for example a heterogeneous composition and/or morphology. Such heterogeneous anodically coloring layers can be used to better tune the properties of a device.
Claims21
A method of fabricating an electrochromic stack, the method comprising:
- depositing a first electrochromic (EC) sublayer of an EC layer comprising a cathodically tinting electrochromic material;
- depositing a second EC sublayer of the EC layer;
- and
- depositing a counter electrode (CE) layer;
- wherein the CE layer consists of a single layer with a composition gradient increasing in a direction away from the EC layer, thereby enabling controlled release of ions from different depths within the CE layer based on applied voltage.
