Method and apparatus to transfer coat uneven surface

Abstract

A method and apparatus for transferring material on at least a portion of an uneven surface of a substrate in the manufacture of photovoltaic cells, which may include, but is not limited to a thin-film solar substrates (3-D TFSS). An apparatus for transfer coating onto an uneven surface comprising an applicator roll, a transport roll, a heating device, a drying system, a conveying system, a reservoir, a blade, and a substrate. A method for positioning a substrate, selectively coating the material on an uneven surface, compressing the material to conform at the uneven surface, heating the material to a temperature more than that of the substrate, and drying the material to form continuous material coverage on said uneven surface. A method and apparatus for passing the substrate in a controlled environment, agitating the material prior to step of selectively coating, and heating the conveying plane.
