Summary: | A method of fabricating solar cell, solar laminate and/or solar module string is provided. The method may include: locating a metal foil over a plurality of semiconductor substrates; exposing the metal foil to laser beam over selected portions of the plurality of semiconductor substrates, wherein exposing the metal foil to the laser beam forms a plurality conductive contact structures having of locally deposited metal portion electrically connecting the metal foil to the semiconductor substrates at the selected portions; and selectively removing portions of the metal foil, wherein remaining portions of the metal foil extend between at least two of the plurality of semiconductor substrates. |
