Abstract
One exemplary embodiment of an electrochromic thin-film material comprises a metal-chalcogen compound; and/or a mixture or solid solution of one or more metal-rich metal-chalcogen compounds and/or lithium. One or more of the metals comprise Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Sb, or Bi, or combinations thereof; and one or more of the chalcogens comprise O, S, Se, or Te, or combinations thereof.
Claims20
An electrochromic thin-film material, comprising a metal-rich metal-chalcogen compound of at least one metal and at least one chalcogen, in which an atomic ratio of a total amount of chalcogens to a total amount of metals other than lithium is less than about 2:1.
An all-solid-state electrochromic device, comprising:
- a transparent base material;
- and
- an electrochromic multilayer-stack structure formed on the transparent base material, the electrochromic multilayer-stack structure comprising:
- a first transparent-conductive film;
- an ion-storage layer formed on the first transparent-conductive film;
- a solid-electrolyte layer formed on the ion-storage layer;
- and
- an electrochromic layer formed on the solid-electrolyte layer, the electrochromic layer comprising an electrochromic thin-film material comprising a metal-rich metal-chalcogen compound of at least one metal and at least one chalcogen, in which an atomic ratio of a total amount of chalcogens to a total amount of metals other than lithium is less than about 2:1.
