Document Type and Number:
Japanese Patent JP2637274
Kind Code:
B2
Abstract:
An electrochromic window (10) includes a first transparent substrate (14), an electroconductive film electrode (16), a transparent electrochromic film (18) in contact with said electroconductive film (16), an ion-conductive layer (26) in contact with said electrochromic film (18), a counter electrode (22) in contact with said ion-conductive layer (26), and a second transparent substrate (24) overlaying the counter electrode (22). A preferred copolymer electrolyte is a reaction product of a sulfonic acid monomer such as acrylamidomethylpropane sulfonic acid or ethylene sulfonic acid, and a hydrophilic acrylate comonomer such that the copolymer is curable with ultraviolet radiation. The optimum moisture content of the ion-conducting polymer sheet (26) is maintained by means of a moisture vapor barrier (38) surrounding the perimeter of the cell. A plurality of bus bars (34) extend across the electroconductive film electrode (16) to distribute electrical current throughout the film electrode and provide a more uniform current density between the film electrode (16) and the counter electrode (22).
