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.

Abstract: A photoactive component has an electrode and an opposing electrode. The electrodes have at least one organic layer system arranged between them, also having at least two photoactive layer systems and, between the photoactive layer systems, at least two different transport layer systems have the same charge carrier type. In this case, one transport layer system matches one of the two photoactive layer systems in energy terms, while the other transport layer system is of transparent design.

Abstract: A photoactive component comprising organic layers, in particular a solar cell comprising a photoactive i-layer system, contains at least one mixed layer. The mixed layer contains at least one donator material and one acceptor material, and thus forms a donator-acceptor system. The donator material and the acceptor material of the mixed layer are non-polymer materials. In a vacuum, the donator material has an evaporation temperature which is at least 150° C. lower than the evaporation temperature of the acceptor material and has an inverted layer sequence with an n-i-p, i-p, or n-i structure of an n-layer, i-layer, or p-layer system respectively. The organic photoactive i-layer system is applied directly onto the cathode or onto an electron-conducting n-material system.
