ABSTRACT:
There is described a semiconductor solar cell of improved efficiency. The cell has a built-in electric field which extends from the surface of the cell to the interior to keep minority carriers away from the surface whereby recombination at the surface is reduced. Interior contacts are provided whereby current flow along the surface of the device to contacts is avoided to reduce surface resistance and recombination.
