A back contact solar cell is described which includes a semiconductor light absorbing layer; a first-level metal layer (Ml), the Ml metal layer on a back side of the light absorbing layer, the back side being opposite from a front side of the light absorbing layer designed to receive incident light; an electrically insulating backplane sheet backside of said solar cell with the Ml layer, the backplane sheet comprising a plurality of via holes that expose portions of the Ml layer beneath the backplane sheet; and an M2 layer in contact with the backplane sheet, the M2 layer made of a sheet of pre-fabricated metal foil material comprising a thickness of between 5-250 μm, the M2 layer electrically connected to the Ml layer through the via holes in the backplane sheet. |
