Abstract: A method for manufacturing an electrochromic window positions a pattern of conductive lines over a first transparent substrate, a transparent conductive film over the pattern of conductive lines and first transparent substrate, and an electrochromic layer over the transparent conductive film, wherein the transparent conductive layer is a physical barrier separating the electrochromic layer from the pattern of conductive lines. The first transparent substrate may be flexible. The pattern of conductive lines and transparent conductive film may be deposited and processed at a temperature less than 180 degrees C. The pattern of conductive lines may be deposited on the first transparent substrate by printing techniques.
