    摘要: 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.

    摘要: A photovoltaic apparatus includes a plurality of approximately spherical photoelectric conversion elements including a second semiconductor layer located outside a first semiconductor layer, for generating photoelectromotive force therebetween. The second semiconductor layer has an opening through which part of the first semiconductor layer is exposed. The apparatus also includes a support having first and second conductors and an insulator disposed between the conductors for electrically insulating the conductors from each other. The support has recesses adjacent to each other, the inside surfaces of which are constituted by the first conductor. The photoelectric conversion elements are disposed in respective recesses so that the elements are illuminated with light reflected by part of the first conductor that constitutes the recess. The first conductor is electrically connected to the second semiconductor layers of the photoelectric conversion elements, and the second conductor is electrically connected to the exposed portions of the first semiconductor layers.
