Abstract
An electrochromic device is provided. The device includes a substrate and an electrochromic stack on the substrate. The stack includes a first set of bus bars, a first transparent conductive layer, at least one electrochromic layer, a second transparent conductive layer, and a second set of bus bars, wherein at least one of the first transparent conductive layer or the second transparent conductive layer includes resistivity that varies by horizontal location according to a resistivity profile. In some embodiments the resistivity profile has a vertical component that may or may not be in addition to the horizontal component. Various embodiments of these materials can be tuned as to profiles of vertical resistance and horizontal sheet resistance.
