Verfahren zur Herstellung einer Solarzelle und Solarzelle

摘要

The invention relates to a solar cell with so-called buried contacts in recesses (7) on a first surface (2). On a lateral face (4), a metal layer (12) is produced that extends into a lateral zone (9) of a second surface (3) opposite the first surface (2), said metal layer serving as a first electrode (14). On the second surface (3) a second electrode (15), electrically separate from the first electrode (14), is produced so that the solar cell is provided with a back connection.
