Abstract: Strings of solar cells having laser assisted metallization conductive contact structures, and their methods of manufacture, are described. For example, a solar cell string includes a first solar cell having a front side and a back side, and one or more laser assisted metallization conductive contact structures electrically connecting a first metal foil to the back side of the first solar cell. The solar cell string also includes a second solar cell having a front side and a back side, and one or more laser assisted metallization conductive contact structures electrically connecting a second metal foil to the back side of the second solar cell. The solar cell string also includes a conductive interconnect coupling the first and second solar cells, the conductive interconnect including a strain relief feature.

Abstract: Wire-based metallization and stringing techniques for solar cells, and the resulting solar cells, modules, and equipment, are described. In an example, a string of solar cells includes a plurality of back-contact solar cells, wherein each of the plurality of back-contact solar cells includes P-type and N-type doped diffusion regions. A plurality of conductive wires is disposed over a back surface of each of the plurality of solar cells, wherein each of the plurality of conductive wires is substantially parallel to the P-type and N-type doped diffusion regions of each of the plurality of solar cells. One or more of the plurality of conductive wires adjoins a pair of adjacent solar cells of the plurality of solar cells and has a relief feature between the pair of adjacent solar cells.
