Germanium solar cell and method for the production thereof

The present invention is related to a method for the passivation and contacting of a surface of a germanium substrate, comprising the steps of : - providing said germanium substrate with a first surface; - producing a passivation layer of amorphous silicon material on said first surface; - producing a contact layer of metal on said passivation layer; - applying a diffusion step, such that said germanium surface is contacted by said contact layer, through said passivation layer. The invention is equally related to a passivated Ge-substrate comprising metal contacts obtained by said diffusion step.
