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.

Abstract: Several of the films that comprise various energy producing or control devices, for example, electrochromic devices, lithium batteries, and photovoltaic cells, are sensitive to moisture in some way. They may be especially vulnerable to moisture at particular stages during their fabrication. It may also be highly desirable during fabrication to be able to wash particulates from the surface. The particulates may be generated some aspect of the fabrication process, or they may arise from the environment in which the fabrication takes place. This invention shows ways to remove said particles from the surface without incurring the damage associated with typical washing processes, resulting in higher manufacturing yields and better device performance.
