  • METHOD FOR DOPING SILICON SHEETS
    Publication number: 20190164761
    Abstract: A method of doping a silicon wafer in order to fabricate a photovoltaic cell, the method including the steps of: performing a first doping operation of at least a first portion (11) of a surface (10) of the silicon wafer; forming an oxide layer (40) on the partially doped surface (10); and performing a second doping operation through the oxide layer (40), so as to dope another portion (12) of the surface (10) of the silicon wafer.
    Type: Application

  • Method for texturing a photovoltaic cell
    Patent number: 8513049
    Abstract: A method for texturing an active surface of a photovoltaic cell in single-crystal silicon or poly-crystal silicon includes depositing a resin on the active surface of the cell, texturing the resin on the active surface with geometric patterns, and texturing the active surface of the cell by eliminating the deposited resin. The depositing of the resin is preceded by pre-texturing the resin on a depositing tool. The texturing step of the resin on the active surface is simultaneous with the depositing of the resin on the active surface.
