Abstract

A semiconductor component, especially a solar cell comprises a semiconductor substrate of a planar design having a first side and a second side lying opposite thereto, at least one contact structure arranged on at least one side of the semiconductor substrate, the at least one contact structure exhibiting a diffusion barrier to prevent the diffusion of ions from the contact structure into the semiconductor substrate.
