Abstract:
1. A method for fabricating a photovoltaic cell using a large scale implant process, the method comprising: providing a tile shaped semiconductor substrate, the tile shaped semiconductor substrate having a surface region, a cleave region and a first thickness of material to be removed between the surface region and the cleave region; introducing through the surface region a plurality of hydrogen particles operable in substantially a protonic mode within a vicinity of the cleave region using a high energy implantation process; coupling the surface region of the tile shaped semiconductor substrate to a first surface region of a substrate, the substrate comprising the first surface region and a second surface region; cleaving the semiconductor substrate to remove the first thickness of material from the tile shaped semiconductor substrate; and forming a solar cell from at least first thickness of material characterized by the tile shape overlying the substrate.
