Abstract
An electrochromic device is provided. The device includes a first transparent substrate and a second transparent substrate and a first electrically conductive layer and a second electrically conductive layer. A first bus bar is in contact with the first electrically conductive layer and a second bus bar in contact with the second electrically conductive layer. The first and second electrically conductive layers are patterned with sets of scribed lines substantially parallel to the corresponding bus bar, wherein the sets of scribed lines are made up of a series of collinear segments, which are gaps in the electrically conductive layer, wherein the length of the collinear segments, the period, the valve width and the offset between segments in adjacent scribed lines determines the resistance to the flow of electrons traversing a set of scribed lines in the direction substantially perpendicular to the corresponding bus bar.
