Abstract (en)

[origin: WO2015036181A1] The invention relates to a method for producing a solar cell (1) from crystalline semiconductor material, wherein a first doping region (5) is formed by means of ion implantation (S2) of a first dopant in a first surface (3a) of a semiconductor substrate (3), and a second doping region (7) is formed by means of ion implantation (S3) or thermal indiffusion of a second dopant in the second surface (3b) of the semiconductor substrate. After the doping of the second surface, a cap (9b) acting as an outdiffusion barrier for the second dopant is applied and an annealing step (S4) is subsequently carried out.
