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, 5) provided on both sides of the photoactive layer (4). In order to provide advantageous construction ratios, it is suggested that an electrically insulating transition layer (6), having a thickness of at most 5 nm, be provided between at least one electrode (5) and the photoactive layer (4).
