Patent number: 9947812Abstract: Approaches for the metallization of solar cells and the resulting solar cells are described. In an example, a method of fabricating a solar cell involves forming a plurality of alternating N-type and P-type regions in or above a substrate. The method also involves forming a metal seed layer on the plurality of alternating N-type and P-type regions. The method also involves patterning at least a portion of the metal seed layer at regions in alignment with locations between the alternating N-type and P-type regions. The method also involves, subsequent to the patterning, etching to form trenches at the locations between the alternating N-type and P-type regions, isolating the alternating N-type and P-type regions from one another.Type: GrantFiled: March 28, 2014Date of Patent: April 17, 2018Assignee: SunPower CorporationInventors: Gabriel Harley, Scott Harrington, David D.
