NOVELTY - A solar cell (100), i.e. bipolar front contact solar cell comprises silicon substrate (101), P-type doped polysilicon layer (108) formed on back surface of substrate, N-type doped polysilicon layer (106) formed on front surface of substrate, first dielectric layer between P-type doped polysilicon layer and back surface of substrate, second dielectric layer between N-type doped polysilicon layer and front surface of substrate, first metal contact in electrical connection to P-type doped polysilicon layer, and second metal contact in electrical connection to the N-type doped polysilicon layer.    USE - A solar cell (claimed), i.e. bipolar front contact solar cell.    ADVANTAGE - The solar cell has low cost and is highly-efficient. The metal contact in the solar cell provides a negative polarity terminal that allows an external electrical circuit to be coupled to and be powered by the solar cell.    DETAILED DESCRIPTION - A solar cell (100), i.e. bipolar front contact solar cell comprises a silicon substrate (101); a P-type doped polysilicon layer (108) formed on a back surface of the substrate, where the P-type doped polysilicon layer forms a backside junction with the substrate; an N-type doped polysilicon layer (106) formed on a front surface of the substrate, where the N-type doped polysilicon layer makes an electrical connection to the substrate; a first dielectric layer between P-type doped polysilicon layer and back surface of the substrate; a second dielectric layer between N-type doped polysilicon layer and front surface of the substrate; a first metal contact making an electrical connection to the P-type doped polysilicon layer on the backside of the solar cell; and a second metal contact making an electrical connection to the N-type doped polysilicon layer on the front side of the solar cell, where the first and second metal contacts are configured to allow an external electrical circuit to be powered by the solar cell. The cell has a front side facing the sun to collect solar radiation during normal operation and a backside opposite to the front side. The cell further comprises antireflective layer (103) on a textured front surface of the substrate, where the antireflective layer comprises silicon nitride. An INDEPENDENT CLAIM is included for a method for fabricating a solar cell.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a solar cell.
