PROBLEM TO BE SOLVED: To provide a photovoltaic cell formed such that charge transport between a photoactive layer and electrodes is increased to elevate a short-circuit current.SOLUTION: A photovoltaic cell is provided which has: a photoactive layer (4) made of two molecular components, namely an electron donor and an electron acceptor, particularly a conjugated polymer component and a fullerene component; and two metallic electrodes (2, 6) provided on both sides of the photoactive layer (4). An intermediate layer (5) made of a conjugated polymer is provided between the photoactive layer (4) and at least one of the electrodes (2, 6). The polymer has doping corresponding to the electrode potential and, in regard to the electron energy band, has an energy gap between the valence band and the conduction band of at least 1.8 eV. |
