SOLAR CELL AND METHOD FOR MANUFACTURING OF SUCH A SOLAR CELL

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.
