  • METHOD FOR PRODUCING A SOLAR CELL HAVING A TWO-STAGE DOPING
    Publication number: 20110186116
    Abstract: Method for producing solar cells with a two-stage doping (9, 11) comprising the method steps of heavy doping (50) of at least a part of the solar cell substrate (1), of at least temporarily protecting doped areas (8), in which heavily doped areas (9) of the two-stage doping (9, 11) should be formed, from an etching medium and etching back (54; 62, 64; 72, 74) unprotected doped areas (17) of the solar cell substrate (1) by means of the etching medium, whereby, for the purpose of protecting the doped areas, sacrificial structures (7) are applied (52) on the areas (8) to be protected, which are at least partly etched (54; 62, 64; 72, 74) during etching back (54; 62, 64; 72, 74) of the unprotected doped areas.
