Abstract
Proposed is a silicon solar cell with a substrate body on one side of which an electrical field is generated by an MIS contact to cause separation of charge carriers generated by radiation energy. The minority charge carriers are drawn off in the metal of the MIS contact, whereas the majority charge carriers are conducted away by ohmic contacts arranged on the opposite side. The ohmic contacts are located on elevated areas relative to the substrate surface. Moreover, the side of the substrate body bearing the ohmic contacts is completely covered with at least one passivation layer.
