1. A solar cell comprising:

  • a crystalline semiconductor substrate containing impurities of a first conductive type;

    a tunnel layer positioned on the crystalline semiconductor substrate;

    a semiconductor layer formed on the tunnel layer, the semiconductor layer having a crystallinity less than a crystallinity of the crystalline semiconductor substrate, the semiconductor layer including a first doped region of a second conductive type opposite the first conductive type and a second doped region containing impurities of the first conductive type at a higher concentration than that of the crystalline semiconductor substrate;

    a first electrode connected to the first doped region; and

    a second electrode connected to the second doped region,wherein at least one of the first doped region or the second doped region includes a first portion having a first specific resistance and a second portion having a second specific resistance, the first specific resistance being larger than the second specific resistance.
