Abstract: The color of an electrochromic stack in a tinted state may be modified to achieve a desired color target by utilizing various techniques alone or in combination. A first approach generally involves changing a coloration efficiency of a WOx electrochromic (EC) layer by lowering a sputter temperature to achieve a WOx microstructural change in the EC layer. A second approach generally involves utilizing a dopant (e.g., Mo, Nb, or V) to improve the neutrality of the tinted state of WOx (coloration efficiency changes). A third approach generally involves tailoring a thickness of the WOx layer to tune the color of the tinted stack.
