Abstract (en)

[origin: WO2014147185A1] The invention relates to a method for doping a silicon sheet for producing a photovoltaic cell, said method comprising the steps consisting of: carrying out a first doping of at least one first part (11) of a surface (10) of the silicon sheet; forming an oxide layer (40) on the partially doped surface (10); and carrying out a second doping via the oxide layer (40), such that another part (12) of the surface (10) of the silicon sheet is doped.
