METHOD FOR THE GALVANIC GENERATION OF CONTACT STRUCTURES ON WAFERS FOR THE PRODUCTION OF SOLAR CELLS AND MODULES

摘要

The invention relates to a method for the galvanic generation of contact structures on wafers for the production of solar cells and modules. The back sides are covered on wafers to which back metallization has already been applied and which have back contacts as well as opened surfaces for the contact structures in the anti-reflection and passivation layer of the front side. In the subsequent galvanic steps for generating the contact structures on the front side, the back side contacts are thus protected and are not subjected to attacks during the galvanic process.
