Abstract

Optoelectronic organic component, comprising: a first electrode, a first planarization layer which is disposed on the first electrode, a first injection layer which is disposed on the planarization layer, an organic functional layer which is disposed on the injection layer, a second electrode which is disposed on the organic functional layer, wherein in the case that the first electrode is an anode, the following applies for the energy levels: EF−EHOMO,Inj.≦−EHOMO,Plan. and EF−EHOMO,Inj<EHOMO,Funk. or in the case that the first electrode is a cathode, the following applies for the energy levels: ELUMO,Inj.−EF≦ELUMO,Plan.−EF and ELUMO,Inj.−EF<ELUMO,Funk.−EF, wherein EF is the fermi energy, EHOMO is the energy of the highest occupied energy level of the respective layer and ELUMO is the energy of the lowest unoccupied energy level of the respective layer.
