The invention concerns an optoelectronic component on a substrate comprising a first and a second electrode, the first electrode being disposed on the substrate and the second electrode forming a counter electrode. Disposed between these electrodes is at least one photoactive layer system which comprises at least one donor-acceptor system with organic materials. The counter electrode has at least a first layer (2), comprising a metal or metal alloy, on an intermediate layer (3), comprising an alkaline-earth metal or alkali metal or a metal oxide, and a second layer (4), between 10 and 100 nm thick, on the first.
