Abstract: Disclosed herein are a solar cell and a method of manufacturing the same. The solar cell module includes a semiconductor substrate, a first passivation film located on a front surface of the semiconductor substrate, a second passivation film located on a rear surface of the semiconductor substrate, a front electric field region located on the first passivation film on the front surface of the semiconductor substrate and being of a same conductivity-type as that of the semiconductor substrate, an emitter region located on the second passivation film on the rear surface of the semiconductor substrate and being of a conductivity-type opposite that of the semiconductor substrate, first electrodes conductively connected to the front electric field region, and second electrode conductively connected to the emitter region.

Abstract: A solar cell and a method for manufacturing the same are discussed. The solar cell includes a substrate containing impurities of a first conductive type, an emitter region which is positioned at a front surface of the substrate and contains impurities of a second conductive type opposite the first conductive type, a back passivation layer which is positioned on a back surface of the substrate and has openings, a back surface field region containing impurities of the first conductive type, a first electrode connected to the emitter region, and a second electrode connected to the back surface field region. The back surface field region includes a first back surface field region positioned on the back passivation layer and a second back surface field region, which is positioned at the back surface of the substrate exposed by the openings of the back passivation layer.
