Abstract:
An electrochromic device includes a first substantially transparent substrate having an electrically conductive material associated therewith, a second substantially transparent substrate having an electrically conductive material associated therewith, an electrochromic composition contained within a chamber positioned between the first and second substrates that includes at least one anodic electroactive material, at least one cathodic electroactive material, and at least one solvent, wherein at least one of the anodic electroactive and cathodic electroactive materials is electrochromic, and wherein the electrochromic device exhibits a contrast ratio of at least 20,000:1, a darkening time less than about 30 seconds, and a clearing time of less than about 150 seconds.
