Abstract

A buried grid solar cell is manufactured by a process for metallising one or more metal contacts of a buried grid solar cell having a body of doped semiconductor material, wherein the electrical contact(s) is/are provided by conducting material being arranged in a pattern of one or more grooves into the semiconductor material by an electrolytic metal deposition process comprising a conventional electrolytic bath containing a special combination of per se known additives.
