Abstract: The present invention provides a solar cell whose external color can be adjusted so that redness is suppressed. In the case where a photoelectric conversion layer contains amorphous silicon, an optical absorption layer is provided between the photoelectric conversion layer and a reflecting electrode layer. The optical absorption layer has a light absorbing property mainly in a long wavelength range, while the photoelectric conversion layer (amorphous silicon) has a selective light absorbing property mainly in a short/medium wavelength range. Incident light (solar light) passed through the photoelectric conversion layer further passes through the optical absorption layer and, after that, is reflected by the reflecting electrode layer. That is, remaining light of the incident light absorbed by the optical absorption layer and the photoelectric conversion layer is reflected by the reflecting electrode layer.
