SOLAR CELLS HAVING HYBRID ARCHITECTURES INCLUDING DIFFERENTIATED P-TYPE AND N-TYPE REGIONS WITH OFFSET CONTACTS

Abstract:

A solar cell, and methods of fabricating said solar cell, are disclosed. The solar cell can include a first emitter region over a substrate, the first emitter region having a perimeter around a portion of the substrate. A first conductive contact is electrically coupled to the first emitter region at a location outside of the perimeter of the first emitter region.
