Abstract
A photovoltaic cell is described, having a photoactive layer ( ) 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 ( ) provided on both sides of the photoactive layer ( ). In order to provide advantageous construction conditions, it is suggested that an intermediate layer ( ) 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 ( ) and at least one electrode ( ).
