Assignee: MAXEON SOLAR PTE. LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 4:
5. A photovoltaic assembly, comprising first and second solar cells, each of the first and second solar cells comprising:
a plurality of semiconductor regions disposed in or above a substrate, the substrate comprising a first end and a second end;
a conductive contact structure comprising a first plurality of metal lines and a second plurality of metal lines disposed on the plurality of semiconductor regions, wherein the first plurality of metal lines and the second plurality of metal lines terminate in a staggered fashion at the first and second ends of the substrate, and wherein the staggered fashion comprises alternating long terminations of the first plurality of metal lines along a first direction relative to short terminations of the second plurality of metal lines along the first direction for neighboring ones of the first and second pluralities of metal lines, and wherein the metal lines of the first plurality of metal lines that have long terminations are discontinuous from one another, and the metal lines of the second plurality of metal lines that have short terminations are discontinuous from one another, and wherein the staggered fashion conforms to angled corners of the substrate including alternating long terminations of the first plurality of metal lines along the first direction relative to short terminations of the second plurality of metal lines along the first direction for neighboring ones of the first and second pluralities of metal lines along the angled corners;
an interconnect structure electrically coupling the first and second solar cells between the second end of the substrate of the first solar cell and the first end of the substrate of the second solar cell, the interconnect structure disposed over and electrically contacting portions of the first plurality of metal lines of the first solar cell but not disposed over the second plurality of metal lines of the first solar cell, and the interconnect structure disposed over and electrically contacting portions of the first plurality of metal lines of the second solar cell but not disposed over the second plurality of metal lines of the second solar cell, wherein the interconnect structure extends along the second end of the first solar cell for a full width of the first solar cell and comprises an extension portion comprising two edges parallel to one of the angled corners of the substrate of the first solar cell, and wherein the interconnect structure has one or more cuts there through; and
bond points disposed between the portions of the first plurality of metal lines of the first and second solar cells and the interconnect structure.
