A method for forming a solar cell including steps of (1) providing a semiconductor wafer having an upper surface; (2) applying an electrical contact material to the upper surface, the electrical contact material forming an electrically conductive grid that includes grid lines extending from a bus bar; (3) forming an isolation channel in the semiconductor wafer to define a solar cell portion and a wing portion, wherein the wing portion is electrically isolated from the solar cell portion, and wherein the wing portion is substantially free of the electrical contact material; (4) submerging the semiconductor wafer in a solvent, wherein formation of metal dendrites on the grid lines of the electrically conductive grid is inhibited; and (5) separating the solar cell portion from the wing portion.
