Abstract:
1. A solar cell apparatus comprising: a planar substrate having a top surface; a first solar cell having a perimeter disposed on the top surface of the substrate, wherein the first solar cell has a circular or elliptical shape; and a second solar cell disposed on the top surface of the substrate and electrically connected to the first solar cell, wherein the second solar cell has a partially opened ring shape and the top surface of the substrate is exposed through an open region of the partially opened ring shape of the second solar cell; a third solar cell disposed around the second solar cell, and extending directly along an outside perimeter of the second solar cell; a first bus bar connected to the first solar cell; and a second bus bar connected to the third solar cell; wherein the second bus bar has a ring shape; and wherein the second solar cell extends along the top surface of the substrate and the partially opened ring shape of the second solar cell completely surrounds the perimeter of the first solar cell except at the open region.
