1. A method of disposing a solid polymer film between two opposing, spaced substrates of an electrochromic device, said method including the steps of:

  • providing a first substrate of the electrochromic device, said first substrate comprising a first substantially transparent element having a first transparent conductive surface;

    providing a second substrate of the electrochromic device, said second substrate comprising a second element having a second conductive surface;

    opposing the conductive surface of said first substrate with the conductive surface of said second substrate and spacing said substrates apart with a solid spacer, said spacer and said substrates forming an interpane cavity between said first and second substrates;

    providing a low viscosity monomer composition that includes at least one of (A) a monofunctional monomer and a cross-linking agent and (B) a polyfunctional component capable of cross-linking, said monomer composition further including a plasticizer;

    causing said low viscosity monomer composition to flow into said interpane cavity; and

    with the monomer composition disposed within said interpane cavity, in-situ curing said monomer composition to form a cross-linked solid polymer film.
