ABSTRACT:
A method of fabricating a photovoltaic solar cell is provided. A plurality of generally spherical semiconductor elements are provided. Each of the semiconductor elements has a core and an outer surface surface forming a p-n junction. An anti-reflection coating is deposited on the outer surface of each of the semiconductor elements and each of the semiconductor elements is bonded into a perforated aluminum foil array thereby providing ohmic contact to a first side of the p-n junction. The anti-reflection coating is removed from a portion of each of the semiconductor elements and then the core is exposed, thereby allowing ohmic contact to be made to a second side of the p-n junction.
