Electrically contactable grids manufacture

摘要

A method for manufacturing one or more electrically contactable grids on at least one surface of a semiconductor substrate for use in a solar cell product includes the following. A heat-sensitive masking agent layer is deposited on the surface of the substrate of the solar cell product. The masking agent layer is locally heated to form a grid mask. Selected parts of the masking agent layer defined by locally heating are removed to form openings in the grid mask. A contact metallization is applied on the grid mask.
