Abstract

The extraction of the luminous power internally generated by organic light emitting diodes (OLEDs) is still the most severe limitation in the overall efficiency of these devices. We present a joint theoretical and experimental study aimed to quantitatively evaluate the light outcoupling limitations of planar p-i-n type small-molecule OLEDs, both in bottom and top emitting configuration. We discuss the physical origin of these limitations by analyzing internal optical losses and overall light conversion efficiency in OLEDs.
