ABSTRACT:
Solar cells formed of semiconductor discrete spheres of P-type interior having an N-type skin are disclosed. The semiconductor spheres are pressed between a pair of aluminum foil members. A plurality of metal pads are formed to the P-type material of the discrete spheres to provide electrical contacts. The aluminum foils are flexible and electrically insulated from one another. One of the foils is electrically connected to the N-type skin of the discrete semiconductor sphere, and the other is electrically connected to the P-type interior of the sphere by means of the metal pads. The cells are patterned in a foil matrix forming an array. Multiple arrays can be interconnected to form a module of solar cell elements for converting sun light into electricity.
