Abstract: A solar cell includes a semiconductor substrate having a first conductivity type, an emitter layer on a surface of the semiconductor substrate, the emitter layer having a second conductivity type different from the first conductivity type, and electrodes including a first electrode electrically connected to the emitter layer, and a second electrode electrically connected to the semiconductor substrate. The emitter layer includes a high-concentration doping portion adjacent to the first electrode, and a low-concentration doping portion in a region that does not include the high-concentration doping portion. The low-concentration doping portion has a higher resistance than the high-concentration doping portion. The high-concentration doping portion includes a first region having a first resistance, and a second region having a second resistance higher than the first resistance.
