Wire-based metallization and stringing for solar cells
Wire-based metallization and stringing techniques for solar cells, and the resulting solar cells, modules, and equipment, are described. In an example, a substrate has a surface. A plurality of N-type and P-type semiconductor regions is disposed in or above the surface of the substrate. A conductive contact structure is disposed on the plurality of N-type and P-type semiconductor regions. The conductive contact structure includes a plurality of conductive wires, each conductive wire of the plurality of conductive wires essentially continuously bonded directly to a corresponding one of the N-type and P-type semiconductor regions.
