Patent number: 11757049Abstract: A bifacial solar cell module includes solar cells that are protected by front side packaging components and backside packaging components. 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. The transparent and reflective portions may be integrated with a backsheet, e.g., by printing colored pigments on the backsheet. The reflective portion may also be on a reflective component that is separate from the backsheet. In that case, the reflective component may be placed over a clear backsheet before or after packaging.Type: GrantFiled: January 29, 2019Date of Patent: September 12, 2023Assignee: MAXEON SOLAR PTE.

Publication number: 20230070805Abstract: 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.Type: ApplicationFiled: November 3, 2022Publication date: March 9, 2023Inventors: Benjamin Ian Hsia, GABRIEL HARLEY, TAESEOK KIM, RICHARD HAMILTON SEWELL, SUNG DUG KIM
