Abstract:
1. An electrochromic device, comprising: a first substrate spaced from a second substrate; a first conductive member formed over at least a portion of the first substrate; a first electrochromic material formed over at least a portion of the first conductive member, the first electrochromic material comprising an organic material; a second conductive member formed over at least a portion of the second substrate; a second electrochromic material formed over at least a portion of the second conductive member, the second electrochromic material comprising an inorganic material; and an ionic liquid positioned between the first electrochromic material and the second electrochromic material, wherein the first electrochromic material comprises one or more coloring semi-conducting polymers, the first electrochromic material comprises a multi-layer structure, and the first electrochromic material comprises poly(3-octylthiophene-2,5-diyl) and at least one additional layer selected from polyethylene dioxythiophene, polypropylene dioxythiophene, or polydimethyl propylene dioxythiophene.
