Abstract
The invention provides an IG unit comprising two panes and a between-pane space located between the two panes. A desired surface of a selected one of the two panes bears a coating comprising both a transparent conductive oxide film, and an overcoat film located over the transparent conductive oxide film. The IG unit further comprises a bus bar and a transparent conductor bridge each located over the desired surface. The bus bar is spaced apart from the coating and is connected electrically to the transparent conductive oxide film by virtue of the transparent conductor bridge extending from the bus bar to a top surface of the overcoat film. In some embodiments, the IG unit further comprises a frit located over the desired surface and extending around a perimeter thereof. The bus bar is located over the frit. Certain embodiments provide a refrigerator having a door comprising such an IG unit.
