Abstract: Metallization of semiconductor substrates using a laser beam, and the resulting structures, e.g., micro-electronic devices, semiconductor substrates and/or solar cells, solar cell circuit, solar cell strings, and solar cell arrays are described. A solar cell string can include a plurality of solar cells. The plurality of solar cells can include a substrate and a plurality of semiconductor regions disposed in or above the substrate. A plurality of conductive contact structures is electrically connected to the plurality semiconductor regions. Each conductive contact structure includes a locally deposited metal portion disposed in contact with a corresponding one of the semiconductor regions.

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.
