Abstract

The present invention relates to a method comprising the steps: a) providing a layered structure applicable for preparing an organic electronic device, comprising: aa) a substrate comprising a first electrode structure and a non-electrode part; bb) a grid formed by a grid material, wherein open areas of the grid are arranged above at least a part of the first electrode structure and the grid material is arranged above at least a part of the non-electrode part; and cc) a layer stack comprising at least one redox-doped layer having a conductivity of at least 1E−7 S/cm, the layer stack being deposited on the grid; wherein the optical density measured by absorption spectroscopy of the grid material is higher than the optical density of the open areas; and b) irradiating light pulses having a duration of <10 ms and an energy of 0.1 to 20 J/cm2 per pulse, alternatively 1 to 10 J/cm2, onto the layered structure; an organic electronic device obtainable this way and a device comprising said organic electronic device.
