NOVELTY - The cell (100) has a first conductive type first semiconductor layer (11a) placed on a surface of a first intrinsic semiconductor layer (12). A second conductive type second semiconductor layer (15) is placed on a back surface of a semiconductor substrate (10). A second intrinsic semiconductor layer (14) is placed between the second semiconductor layer and the substrate. A first conductive type third semiconductor layer (17) is placed on the back surface of the substrate. A third intrinsic semiconductor layer (16) is placed between the third semiconductor layer and the substrate.    USE - Solar cell for supplying power to external devices.    ADVANTAGE - The cell includes an anti-reflective layer to reduce light reflection loss on the surface of the solar cell so as to increase selectivity of a specific wavelength region. The cell includes a passivation layer with a double layer structure to implement an excellent field passivation effect, thus increasing opening voltage of the solar cell. The field passivation effect forms electric field on the surface of the semiconductor substrate to reduce and/or prevent surface movement of charges, thus reducing recombination of charges. The second intrinsic semiconductor layer improves the p-n junction characteristics. The third intrinsic semiconductor layer suppresses the recombination of carriers to improve photoelectric conversion efficiency of the solar cell. The passivation layer improves passivation characteristics between the second semiconductor layer and the third semiconductor layer so as to increase the opening voltage and reduce shunting resistance between the second semiconductor layer and the third semiconductor layer. The cell includes a layer of cathode and anode patterned by an etching process using etching paste so as to reduce manufacturing cost, thus facilitating mass production by simplifying the manufacturing process of the cathode and the anode.
