ABSTRACT:
A method is provided for decreasing radiative heat transfer and adjustably limiting visible light and near infrared radiation transfer and glare through a window. The method comprises the steps of: (a) mounting within a frame of the window a plurality of spaced window panes, a first and second of the panes having opposing faces; (b) assembling between the opposing faces a conductive polymer cell, the cell having a first wall composed of a transparent conductive layer affixed to the first pane and having deposited thereupon an electroactive electro-optically responsive conductive polymer, and a second wall comprised of a transparent conductive layer coated on the second pane, the layer being optionally coated with a second electro-optically responsive polymer, the first and second walls delimiting a cavity containing an ion-conducting electrolyte which contacts opposing surfaces of the first and second walls, and (c) applying a potential between the first and second walls to provide a selected light transmittance upon passage of current therebetween.
