Abstract
A composite solar cell comprises a spectroscopic element, a first photoelectric conversion element, and a second photoelectric conversion element. The first photoelectric conversion element is positioned in a first direction of the spectroscopic element and the second photoelectric conversion element is positioned in a second direction of the spectroscopic element. The first photoelectric conversion element is a perovskite-type photoelectric conversion element containing, in a light absorbing layer, a perovskite crystal structure material represented by a general formula RNHMX. A band gap of a light absorbing layer of the second photoelectric conversion element is narrower than the band gap of the light absorbing layer of the first photoelectric conversion element. The spectroscopic element preferentially outputs the short wavelength light of the incident light in the first direction and preferentially outputs the long wavelength light of the incident light in the second direction.
