摘要： A self-biased solar cell and a module adopting the solar cell. The self-biased solar cell includes a semiconductor substrate of first conductivity type, a semiconductor layer of second conductivity type disposed adjacent to the first surface of the semiconductor substrate, at least one more first electrodes formed adjacent to the semiconductor layer; at least one more dielectric layers formed on the second surface of the semiconductor substrate, at least one or more second electodes formed on the second surface of the semiconductor substrate, the second electodes being disposed adjacent to the dielectric layers, and at least one or more voltage applying electrode formed on the dielectric layers. Therefore, recombination loss of the carriers according to the formation of a back surface field is comparatively decreased, and open voltage and quantum efficiency at a long wavelength are increased.
