Abstract: A photovoltaic (PV) cell comprises a base substrate which comprises silicon and includes at least one doped region. The PV cell further comprises a collector disposed on the doped region of the base substrate and having a lower portion in physical contact with the doped region of the base substrate, and an upper portion opposite the lower portion. The PV cell further comprises an electrically conductive layer which is electrically isotropic or anisotropic and disposed adjacent the collector. The electrically conductive layer is in electrical communication with the base substrate via the collector. The electrically conductive layer comprises a binder and electrically conductive particles comprising at least one metal selected from the group consisting of Group 8 through Group 14 metals of the Periodic Table of Elements. The electrically conductive particles impart isotropic or anisotropic electrical conductivity to the electrically conductive layer.

Abstract: 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.
