Abstract
Solar cells are formed of semi-conductor spheres of P-type interior having an N-type skin are pressed between a pair of aluminum foil members forming the electrical contacts to the P-type and N-type regions. The aluminum foils, which comprise 1.0% silicon by weight, are flexible and electrically insulated from one another. The spheres are patterned in a foil matrix forming a cell. Multiple cells can be interconnected to form a module of solar cell elements for converting sun light into electricity.
