Abstract: The invention relates to a method for the post-treatment of a photovoltaic cell comprising a photoactive layer composed of two molecular components, specifically an electron donor and an electron acceptor, particularly a conjugated polymer component and a fullerene component, and two metal electrodes provided on either side of the photoactive layer, the photovoltaic cell being subjected to heat treatment above the glass transition temperature of the electron donor for a predetermined treatment time. To increase efficiency, it is proposed that the heat treatment of the photovoltaic cell be carried out for at least a portion of the treatment time under the influence of an electric field induced by a field voltage applied to the electrodes of the photovoltaic cell and exceeding the no-load voltage thereof.
