29. A method of increasing an inert gas retention performance of an electrochromic device including a bus bar and a color obscuration material comprising:
-
at least partially coating said bus bar with an over-coating material that is substantially non-porous; and
substantially color-matched to said color obscuration material; andplacing a polymer seal adjacent to the over-coating material, such that the bus bar and over-coating layer extend from a sealed interior portion to locations outside the interior region and spaced apart from the polymer seal. - View Dependent Claims (30, 31)
