1. An electrochromic (EC) element comprising:

  • a first base including a first substrate having a first surface and a second surface opposite the first surface, the second surface carrying a transparent electrode layer that comprises a first optical thin-film structure including a first metal layer sandwiched between first and second dielectric layers, the first and second dielectric layers comprising materials having corresponding refractive indices greater than 1.7;

    a second base having third and fourth surfaces, the first and second bases disposed in a parallel and spaced-apart relationship so as to define a gap therebetween, the second and third surfaces opposing each other; and

    an electrochromic medium located in the gap;

    wherein transmittance of the first base measured in light generated by a standard D65 illuminant exceeds 50 percent.
