Abstract
A semiconductor solar cell capable of converting incident radiation to electrical energy at high efficiency includes a plurality of series-connected unit solar cells formed on a common wafer of semiconductor material. The unit solar cells each include a semiconductor substrate of one conductivity type and a p-n junction formed in the substrate. The light-receiving surface of the cell may have an opaque member thereon, and incident light may be directed onto the portion of that surface not covered by the opaque member. Various embodiments and methods illustrate the invention.
