Abstract

A photoactive component includes organic layers, including a single, tandem or multiple cell with two electrodes and, between the electrodes, a photoactive acceptor-donor layer system that includes at least three absorber materials. At least two absorber materials are donors or acceptors. One of the two absorber materials is configured as donors or acceptors absorbing at greater wavelengths than the other absorber material and one of the two absorber materials have a lower Stokes shift and/or a lower absorption width than the other absorber material.
