Abstract (en)
[origin: WO2015044109A1] The invention relates to a method for producing a metallic contact-connection of a photovoltaic solar cell, comprising the following method steps: A providing a semiconductor substrate and B applying an aluminum-containing contact-connection layer indirectly or directly to a side of the semiconductor substrate. The invention is characterized in that in a method step C a diffusion barrier layer, which acts as a diffusion barrier at least with respect to aluminum, is applied indirectly or directly to the contact-connection layer, and in a method step D a solderable layer composed of a solderable material is applied indirectly or directly to the diffusion barrier layer, and in that the diffusion barrier layer and the contact-connection layer are applied by means of a PVD method.
