Abstract: The inventive concept discloses a solar cell and a method for manufacturing the same. The solar cell includes a semiconductor substrate, an emitter layer disposed on one surface of the substrate, and a cooling layer disposed on one surface of the emitter layer, and the cooling layer absorbs a far-infrared ray from irradiated sunlight and emits a wavelength of the absorbed far-infrared ray.
