1. 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.

Abstract
An electrochromic device, such as a window or mirror, is disclosed that includes first and second substrates each having an inner surface spaced apart from one another to define a chamber, first and second electrodes carried on the inner surface of the second substrate and disposed thereon to be electrically isolated from one another, and an electrochromic medium disposed in the chamber. The electrodes may be disposed on the inner surface of the second substrate in substantially co-planar relation. Alternatively, the electrodes may be arranged in a stacked relation, with a layer of dielectric material provided therebetween.
