Solderable polymer thick film conductive electrode composition for use in thin-film photovoltaic cells and other applications

摘要

The invention is directed to a polymer thick film conductive composition comprising (a) a conductive silver-coated copper powder; and (b) an organic medium comprising two different resins and organic solvent, wherein the ratio of the weight of the conductive silver-coated copper powder to the total weight of the two different resins is between 5:1 and 45:1.;The invention is further directed to a method of electrode grid and/or bus bar formation on thin-film photovoltaic cells using the composition and to cells formed from the method and the composition.
