摘要

An electrochromic device, comprising: front and rear spaced elements each having front and rear surfaces; a layer of conductive material disposed on said rear surface of said front element and said front surface of said rear element, and a perimeter sealing member that defines a chamber between said front and rear spaced elements, where said chamber contains an electrochromic medium, said electrochromic medium comprising at least three electroactive materials, at least two of which are electrochromic, where the redox potentials of all of said electroactive materials that are anodic are within about 200 mV of one another, and wherein the redox potentials of all of said electroactive materials that are cathodic are within about 200 mV of one another.
