Abstract: Disclosed is a solar cell including a semiconductor substrate, a protective-film layer on a surface of the semiconductor substrate, a polycrystalline semiconductor layer over the protective-film layer, a first conductive area formed by selectively doping the semiconductor layer with a first conductive dopant, a second conductive area doped with a second conductive dopant and located between neighboring portions of the first conductive area, an undoped barrier area located between the first conductive area and the second conductive area, a first electrode connected to the first conductive area, and a second electrode connected to the second conductive area. Each of the first conductive area and the second conductive area includes a second crystalline area having a crystalline structure different from that of the barrier area, and the second crystalline areas of the first and second conductive areas include a second polycrystalline area and a fourth crystalline area having different depths.
