Abstract
An electrochromic device including: a first substantially transparent substrate having an electrically conductive material associated therewith; a second substrate having an electrically conductive material associated therewith; an electrochromic medium contained within a chamber positioned between the first and second substrates which includes: at least one solvent; at least one anodic material; and at least one cathodic material, wherein both of the anodic and cathodic materials are electroactive and at least one of the anodic and cathodic materials is electrochromic; wherein at least one of a seal member, the first substrate, the second substrate, and the chamber includes a plug associated with a fill port; and wherein the plug is at least partially cured with at least one photoinitiator and at least one photosensitizer upon exposure to electromagnetic radiation having a wavelength from about 350 nm to about 420 nm.
