Abstract
Disclosed is a solar battery comprising a multi-layered "p-n" junction structure, which has a plurality of inwardly converging recesses to partially expose the inner "p-n" junctions to the sun light.
Claims6
A solar battery of homoepitaxial or heteroepitaxial structure comprising a series connected stack of alternately arranged planar layers of p and n semiconductor material, each pair of adjacent layers of opposite conducting type forming a photovoltaic junction therebetween, each said junction being parallel to the plane of the layers, with ohmic electrodes lying between each said pair, said stack having top and bottom major surfaces and a plurality of grooves in the top major surface of said stack, said grooves extending through said planes of the said junctions, the exposed surfaces of said grooves being inclined to said junction planes for receiving impinging radiation.
