Abstract
A high-concentration solar cell includes an epitaxial layer structure, an upper patterned electrode on the top surface, and a back electrode on the back surface. The upper patterned electrode includes a primary pattern and a secondary pattern, where the primary pattern is composed of a series of small metal isosceles trapezoids around the perimeter of the cell. The narrower base of each metal trapezoid points toward an interior of the cell. A lead soldering pad is located within each metal trapezoid for being soldered to an external conductor for carrying the solar cell current. The secondary pattern consists of thin spaced conductors that connect to the angled sides and base of each trapezoid and spread current across the top surface of the cell. The current along the angled sides of each trapezoid is well-distributed to all the spaced conductors connected to the angled sides to avoid current crowding.
