A multilayer back electrode for a photovoltaic thin-film solar cell includes, in the following sequence: at least one bulk back electrode layer containing at least one of V, Mn, Cr, Mo, Co, Zr, Ta, Nb, and W; at least one conductive barrier layer; and at least one ohmic contact layer containing (i) at least one first ply adjacent to the at least one conductive barrier layer, the at least one first ply containing at least one of Mo, W, Ta, Nb, Zr and Co, and (ii) at least one second ply not adjacent to the at least one barrier layer, the at least one second ply containing at least one metal chalcogenide. |
