Abstract
An electrode for an electrochromic device includes a resistive layer disposed over a conductive layer. The resistive layer is disposed between the conductive layer and an electrochromic material in the electrochromic device. The electrode reduces non-uniform response of the electrochromic material when the electrochromic device is in operation.
Claims15
