Photovoltaic cell
First Claim
1. A photovoltaic cell having 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 having two metallic electrodes (2, 6) provided on both sides of the photoactive layer (4), characterized in that an intermediate layer (5) made of a conjugated polymer, which has a doping corresponding to the electrode potential and, in regard to the electron energy, has a band gap between the valence band and the conduction band of at least 1.8 eV, is provided between the photoactive layer (4) and at least one electrode (2,6).

Abstract
A photovoltaic cell is described, having 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 having two metallic electrodes (2, 6) provided on both sides of the photoactive layer (4). In order to provide advantageous construction conditions, it is suggested that an intermediate layer (5) made of a conjugated polymer, which has doping corresponding to the electrode potential and, in regard to the electron energy, has a band gap between the valence band and the conduction band of at least 1.8 eV, be provided between the photoactive layer (4) and at least one electrode (2,6).
