摘要： A solar cell includes a silicon semiconductor substrate of a first conductivity type. The substrate has a front surface and a rear surface, of which the front surface is arranged for capturing radiation energy. The rear surface includes a plurality of first electric contacts and a plurality of second electric contacts. The first and second electric contacts are arranged in alternation adjacent to each other. Each first electric contact is a heterostructure of a first type as contact for minority charge carriers, and the front surface of the silicon semiconductor substrate includes a highly doped silicon front surface field layer. The conductivity of the front surface field layer is the first conductivity type.

摘要： A solar panel module includes a transparent carrier and semi-conductor substrate portions that have a front surface and a rear surface. The front surface is arranged for capturing radiation energy. The semiconductor substrate portions are arranged adjacent to each other on the transparent carrier and are separated from each other by a groove. Each semiconductor substrate portion is attached with the front surface to the transparent carrier. Each groove includes a side wall of each of the adjacent semiconductor substrate portions. The front surface of each semiconductor substrate portion is provided with a doped layer of a first conductivity type. Each semiconductor substrate portion includes a first electric contact for minority charge carriers and a second electric contact for majority charge carriers in the semiconductor substrate portion. The first electric contact is arranged on at least the rear surface of the semiconductor substrate portion as a heterostructure of a first type. The hetero junction of the first type includes an intrinsic semiconductor layer on the semiconductor substrate portion and a semiconductor layer of a second conductivity type, opposite to the first conductivity type, on top of the intrinsic semiconductor layer.
