Abstract: A method for manufacturing a multi-junction photoelectric conversion device includes forming a first electrode on a first photoelectric conversion unit including a first semiconductor layer as a photoelectric conversion layer, the first electrode including a plurality of patterned regions separated from one another by separation grooves; and eliminating a leakage existing in the first semiconductor layer by applying a reverse bias voltage between one of the patterned regions of the first electrode and a second photoelectric conversion unit comprising a second semiconductor layer as a photoelectric conversion layer. The application of the reverse bias voltage is performed while irradiating the second photoelectric conversion unit with light, generating a photocurrent in the second photoelectric conversion unit that is larger than a photocurrent in the first photoelectric conversion unit.

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 R1NH3M1X3. 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.

Abstract: A solar cell includes a metal layer and a chalcopyrite compound semiconductor layer in this order on a polyimide film. A manufacturing method according to the present invention includes the following steps in the order: cast applying a polyimide precursor solution onto a support base containing an alkali metal; imidizing the polyimide precursor by heating to form a stacked body including a polyimide film on the support base; forming a metal layer on the polyimide film of the stacked body; and forming a chalcopyrite compound semiconductor layer on the metal layer.
