NOVELTY - The article has photovoltaic cells (10,12) provided with first surface and opposing second surface. First electrical connector segment (22) is provided with portion that performs electrical communication with topside (18) of cells, and is communicated with second electrical connector segment (24) having portion that performs electrical communication with backside (16) of cells. Portion of second electrical connector segment contacting backside of cells is formed of material dissimilar to material of first electrical connector portion contacting topside of cells.    USE - Photovoltaic article.    ADVANTAGE - The electrical connectors for use in photovoltaic cells are used for maintaining electrical contacts within the cells over time by avoiding corrosion due to environmental stress. The electrical connectors are provided with variable material composition along the connector, such that the material composition at any point along the electrical connector is selected and tuned for improved connectivity with the cell surface that is contacted. The stability of the photovoltaic cells is improved. The selection of materials for forming electrical connection segments having dissimilar metallurgy results in improved resistance to corrosive effects on cell surfaces and improved function of the cells over extended periods of time.    DETAILED DESCRIPTION - The first electrical connector segment is formed of material such as tin, copper, silver, gold, platinum, aluminum, molybdenum, zinc, antimony, niobium, chromium, nickel, indium, lead, iron, steel, stainless steel, titanium, tantalum nitride, tin oxide, doped tin oxide, azido deoxyguanosine, doped zinc oxide, graphene, conductive organic polymers or conductive small molecules. The second electrical connector segment is formed of material such as tin, copper, silver, gold, platinum, aluminum, molybdenum, zinc, antimony, niobium, chromium, nickel, indium, lead, iron, steel, stainless steel, titanium, tantalum nitride, tin oxide, doped tin oxide, indium tin oxide, azido deoxyguanosine, doped nitric oxide, graphene, conductive organic polymers or conductive small molecules.
