摘要： A photovoltaic cell comprises a base substrate comprising silicon and including a rear region. A first electrode is disposed on, and is in electrical communication with, the rear region, and comprises a first metal present in the first electrode in a majority amount. A second electrode is spaced from the rear region such that the rear region is free of physical contact with the second electrode. The second electrode is in electrical contact with the first electrode. The second electrode comprises a polymer, a second metal present in the second electrode in a majority amount, and a third metal different from the first and second metals. The third metal has a melting temperature of no greater than about 300 'C. The rear region is in electrical communication with the second electrode via the first electrode. A method of forming the PV cell is also provided.
