1. A variable transmittance electrochromic window comprising:

  • first and second transparent substrates each having outer surfaces and opposed inner surfaces;

    first and second transparent electrodes disposed on the inner surface of at least one of said first and second transparent substrates;

    a seal disposed between said first and second transparent substrates to define a sealed chamber therebetween; and

    an electrochromic layer of reversibly variable transmittance to light disposed in said chamber, said electrochromic layer comprising a solvent, at least one solution based electrochromic material in solution in said solvent, and a cross-linked polymer matrix that results from cross-linking polymer chains, where said polymer chains are formed prior to cross-linking, and said electrochromic material is interspersed in said polymer matrix.
