Fabrication methods and structures relating to backplanes for back contact solar cells that provide for solar cell substrate reinforcement and electrical interconnects as well as Fabrication methods and structures for forming thin film back contact solar cells are described.

High-efficiency solar photovoltaic cells and modules using thin crystalline semiconductor absorbers

A back contact solar cell is described which includes a semiconductor light absorbing layer; a first-level metal layer (M1), the M1 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 M1 layer, the backplane sheet comprising a plurality of via holes that expose portions of the M1 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 &#x3bc;m, the M2 layer electrically connected to the M1 layer through the via holes in the backplane sheet.
