| Abstract: | Abstract— This work aims at explaining and predicting the influence of the thickness of organic materials, dye doping, and space‐charge effects on charge‐carrier transport at different operating temperatures for high current densities (50 ≤ J ≤ 7000 mA/cm2). For the purpose of determining these influences, current‐voltage characteristics for typical electrically doped multilayer organic light‐emitting diodes (OLEDs) have been simulated. The results of the simulations concur with experimental data. |
