NOVELTY - The process comprises providing an n-type silicon wafer with holes forming vias between a front-side and a back-side of the wafer and a p-type emitter extending over the entire front-side and the inside of the holes, applying a conductive metal paste to the holes of the silicon wafer to provide the inside of the holes with a metallization, drying the applied conductive metal paste, and firing the dried conductive metal paste, where the wafer reaches a peak temperature of 700-900 degrees C. The n-type silicon wafer has an anti-reflective coating layer on its front-side.    USE - The process is useful for the production of a metal-wrap-through silicon solar cell.    ADVANTAGE - The process is capable of easily and effectively manufacturing a metal-wrap-through silicon solar cell with improved electric efficiency, long service life and increased product yield and without any damage.    DETAILED DESCRIPTION - The process comprises providing an n-type silicon wafer with holes forming vias between a front-side and a back-side of the wafer and a p-type emitter extending over the entire front-side and the inside of the holes, applying a conductive metal paste to the holes of the silicon wafer to provide the inside of the holes with a metallization, drying the applied conductive metal paste, and firing the dried conductive metal paste, where the wafer reaches a peak temperature of 700-900 degrees C. The n-type silicon wafer has an anti-reflective coating layer on its front-side that leaves out the inside of the holes. The conductive metal paste: has desired fire through capability; comprises an organic vehicle having a content of 10-45 wt.% based on total conductive metal paste composition, and glass frit component (0.25-8 wt.%); and is applied as a conductive metal layer or as a conductive metal plug by printing. The firing is performed as cofiring together with the metal paste consisting of: the conductive metal paste that is applied to the front-side to form a front-side metallization in the form of thin conductive metal collector lines arranged in a pattern for silicon solar cells; and a back-side silver paste that is applied to the backside to form silver back collector contacts. An INDEPENDENT CLAIM is included for a metal-wrap-through silicon solar cell.
