Abstract
A method for forming an electrochromic device includes: forming a first conducting layer on a first substrate; forming a first electrolyte layer on the first conducting layer; forming a second conducting layer on a second substrate; forming an electrochromic layer on the second conducting layer; forming a second electrolyte layer on the electrochromic layer; and laminating the first substrate and the second substrate such that the first electrolyte layer is in contact with the second electrolyte layer.
