1. A method for manufacturing an electrochromic element, the method comprising:

  • providing a first substrate having a first surface, a second surface opposite the first surface, and a first edge surface;

    providing a second substrate having a third surface facing the second surface, a fourth surface opposite the third surface, and a second edge surface;

    providing an electrochromic medium located between the first and second substrates, wherein the electrochromic medium has a light transmittance that is variable upon the application of an electric field thereto; and

    applying a conductive layer on at least a portion of at least a select one of the first surface, the second surface, the first edge surface, the third surface, the fourth surface, and the second edge surface, wherein applying of the conductive layer is accomplished at substantially atmospheric pressure and includes applying at least a select one of metallic particles, an organometallic, a metallo-organic, and combinations thereof, and wherein the conductive layer has a bulk resistivity of greater than or equal to 150 μ
