Abstract

Back contact solar cells including rear surface structures and methods for making same. The rear surface is doped to form an n+ emitter and then coated with a dielectric layer. Small regions are scribed in the rear surface and p-type contacts are then formed in the regions. Large conductive grid areas overlay the dielectric layer. The methods provide for increasing efficiency by minimizing p-type contact areas and maximizing n-type doped regions on the rear surface of a p-type substrate.
