Abstract

A multi-junction solar cell includes a first main surface and a second main surface opposite to the first main surface of a semiconductor body. A topmost pn-junction of a plurality of pn-junctions stacked on top of each other adjoins to the first main surface. A cell edge of the semiconductor body defines a shape of the first and the second main surfaces. An encapsulant on the first main surface provides an environmental protection of the semiconductor body. A mesa groove is provided on the first main surface and penetrates at least the topmost pn-junction. The mesa groove is located adjacent to the cell edge and is created around the circumference of the semiconductor body for providing an inner cell area and a mesa wall, the mesa wall being created between the mesa groove and the cell edge. The mesa groove is filled with the encapsulant.
