Abstract

A method of manufacturing electrically tintable window glass with a variety of sizes and functionalities is described. The method comprises: (a) providing a large format glass substrate; (b) fabricating a plurality of electrically tintable thin film devices on the large format glass substrate; (c) cutting the large format glass substrate into a plurality of electrically tintable pieces, each electrically tintable piece including one of the plurality of electrically tintable thin film devices; (d) providing a plurality of window glass pieces; (e) matching each one of the plurality of electrically tintable pieces with a corresponding one of the plurality of window glass pieces; and (f) laminating each of the matched electrically tintable pieces and window glass pieces. The lamination may result in the electrically tintable device either being sandwiched between the glass substrate and the window glass piece or on the surface of the laminated pieces. The electrically tintable device is an electrochromic device.

Claims
