Abstract:
An electrochromic device comprising:a transparent first substrate having an outer surface and an inner surface; a second substrate having an inner surface spaced apart from said inner surface of said first substrate; a perimeter seal, which, with said inner surfaces of said first and second substrates, defines a chamber therebetween; a first electrode carried on said inner surface of said second substrate; a second electrode also carried on said inner surface of said second substrate, said second electrode being electrically isolated from said first electrode; a UV radiation attenuating material associated with said device; and an electrochromic medium disposed in said chamber between said inner surface of said first substrate and said inner surface of said second substrate, wherein said UV radiation attenuating material reduces the amount of UV radiation impacting a portion of said electrochromic medium.
