This invention discloses a method for generating conduction electrodes of solar cells, which prints conductive slurry to poles of type-N and type-P of a solar cell with a halftone by a silk screen printing technology characterizing that said conduction slurry for screen plate printing is covered with sensitive cellophane and rule or ruleless rugged surfaces appearing on the surface of a conductiveelectrode with this method can stop getting together to a point by melt metals effectively, and metal balls or buds will not be generated on the surface of the conductive electrode even if the thickness of the back conductive electrode is reduced so as to reduce warp of solar cells.
