Patent number: 11947233Abstract: Various embodiments relate to an electrochromic (EC) device that is structured with surface contour features arranged according to a randomized pattern. For example, one or more conductive layers of an EC device may be structured with such surface ablations.

Publication number: 20230077782Abstract: 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.Type: ApplicationFiled: October 28, 2022Publication date: March 16, 2023Applicant: SAGE Electrochromics, Inc.Inventors: Wen Li, Nicolas Antoine Mercadier, Jean-Christophe Giron, Hannah Leung Ray, Xiaoguang Hao, Theo Chevallier, Chloe Bouard, Samuel Emile Dubrenat
