    Abstract: An electrochromic device and method of forming the same is disclosed. The electrochromic device can include a first transparent conductive layer, an electrochromic layer, an electrolyte layer, a counter electrode layer, a second transparent conductive layer, and an adhesion layer between the counter electrode layer and the second transparent conductive layer, where the electrochromic device can undergo at least 2,000 cycles in a Nylon brush test before type 2 defects form. The method can include depositing an electrochromic layer over a first transparent conductive layer, depositing an electrolyte layer, depositing a lithium layer, depositing a counter electrode layer over the lithium layer, depositing a second transparent conductive layer, and heating the layers to form an electrochromic stack, where the lithium layer is combined with the counter electrode layer.

    Abstract: An electrochromic device is structured to selectively switch separate regions to separate transmission levels, based at least in part upon different respective sheet resistances of separate conductive layer regions. Sheet resistance of a conductive layer region can be associated with a transmission level to which a corresponding EC stack region can be switched, and a conductive layer with separate regions having separate sheet resistances causes corresponding EC stack regions to switch to different transmission levels. Sheet resistance in a conductive layer region can be adjusted via various processes, including introducing various chemical species into the conductive layer region to adjust a chemical species distribution in the region, where the chemical species distribution is associated with the sheet resistance of the region, heating conductive layer regions to induce oxidation of the region, adjusting the thickness of a conductive layer region, etc.
