  • Patent number: 9496432
    Abstract: The present invention is related to a method for forming a metal silicide layer on a textured silicon substrate surface. The method includes providing a metal layer on a textured silicon substrate and performing a pulsed laser annealing step providing at least one UV laser pulse with a laser fluence in the range between 0.1 J/cm2 and 1.5 J/cm2 and with a laser pulse duration in the range between 1 ns and 10 ms. Then, the method includes converting at least part of the metal layer into a metal silicide layer. In addition, the present invention is related to the use of such a method in a process for fabricating a photovoltaic cell, wherein the dielectric layer is a surface passivation layer, or wherein the dielectric layer is an antireflection coating.

  • Publication number: 20130199608
    Abstract: A method for fabricating a photovoltaic device, including depositing a TCO-layer on a substrate and annealing the TCO layer by laser irradiation having irradiation parameters, wherein the irradiation parameters are selected such that the annealing includes increasing the haze % of the TCO layer compared to the as deposited TCO layer. Additionally, a TCO layer having a haze % of at least 2% in the visible light wavelength range and a surface roughness of less than 0 nanometer RMS, and a photovoltaic device including such TCO-layer.

  • Publication number: 20130146999
    Abstract: A method for forming a selective contact for a photovoltaic cell is disclosed. The method includes forming a doped contact layer at the surface of a semiconductor substrate and annealing a portion of the doped contact layer with a laser beam, the portion having a 2D-pattern corresponding to at least a portion of a respective selective contact grid. Wherein the laser beam is pulsed and shaped to the 2D-pattern. A photovoltaic cell having a selective contact formed by the method is also provided.
