The front side packaging components include a transparent top cover on a front portion of the solar cell module. The backside packaging components have a transparent portion that allows light coming from a back portion of the solar cell module to reach the solar cells, and a reflective portion that reflects light coming from the front portion of the solar cell module.

Abstract: 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.
