ALL FRONT CONTACT SOLAR CELL

摘要

A photovoltaic solar cell, including an N-side layer proximate to a first planar surface and a P-side layer proximate to a second planar surface that is opposite to the first planar surface, is formed from a circular wafer substrate. An N-side conductive contact is electrically coupled with the N-side layer, and a P-side conductive contact electrically coupled with the P-side layer. The P-side conductive contact and the N-side conductive contact are each disposed proximate to the first planar surface, the circular wafer substrate includes an edge exclusion zone, and the P-side contact is disposed within or proximate to the edge exclusion zone.
