LASER STOP LAYER FOR FOIL-BASED METALLIZATION OF SOLAR CELLS |
摘要 |
Approaches for the foil-based metallization of solar cells and the resulting solar cells are described. For example, a method of fabricating a solar cell involves forming a plurality of alternating N-type and P-type semiconductor regions in or above a substrate. The method also involves forming a paste between adjacent ones of the alternating N-type and P-type semiconductor regions. The method also involves curing the paste to form non-conductive material regions in alignment with locations between the alternating N-type and P-type semiconductor regions. The method also involves adhering a metal foil to the alternating N-type and P-type semiconductor regions. The method also involves laser ablating through the metal foil in alignment with the locations between the alternating N-type and P-type semiconductor regions to isolate regions of remaining metal foil in alignment with the alternating N-type and P-type semiconductor regions. The non-conductive material regions act as a laser stop during the laser ablating. |
