Abstract: A solar cell and method of fabricating the same are provided. The substrate of the solar cell has heavily-doped regions and lightly-doped regions. The anode and the cathode are disposed on the back surface of the substrate, and thus the amount of incident light on the front surface of the substrate is increased. The anode and the cathode are in contact with the heavily doped regions to form selective emitter structure, and thus the contact resistance is reduced. The lightly-doped regions, which are not in contact with the anode and the cathode, have lower saturation current, and thus recombination of hole-electron pairs is reduced, and absorption of infrared light is increased.
