Solar module structures and assembly methods for three-dimensional thin-film solar cells

Abstract

A method for assembling a solar module structure comprises patterning a frontside and a backside of a double-sided printed circuit board coated with metallic foils according to desired frontside and backside interconnect layouts; applying a first coating layer to the rear side of a plurality of three-dimensional thin-film solar cells, each three-dimensional thin-film solar cell comprising: a three-dimensional thin-film solar cell substrate comprising emitter junction regions and doped base regions; emitter metallization and base metallization regions; the three-dimensional thin-film solar cell substrate comprising a plurality of single-aperture unit cells; placing the three-dimensional thin-film solar cells on the frontside of the double-sided printed circuit board; preparing a solar module assembly, comprising: a glass layer; a top encapsulant layer; the plurality of three-dimensional thin-film solar cells on the frontside of the double-sided printed circuit board; a rear encapsulant layer; a protective back plate; and sealing and packaging the solar module assembly.
