Abstract

The invention relates to an electronic device comprising a layer structure of organic layers, wherein said layer structure comprises a p-n-junction between an n-type doped organic layer provided as an organic matrix material doped with an n-type dopant and a p-type doped organic layer provided as a further organic matrix material doped with a p-type dopant, and wherein the n-type dopant and the p-type dopant both are molecular dopants, a reduction potential of the p-type dopant is equal or larger than about 0 V vs. Fc/Fc+, and an oxidation potential of the n-type dopant is equal or smaller than about −1.5 V vs. Fc/Fc+.
