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.
