The external quantum efficiency (EQE) is the number of photons emitted by an OLED divided by the number of injected charges. Photons are generated in the device emitting layer (EML), but most of the light is not escaping the device because of three main loss mechanisms: Total Internal Reflection, Absorption Losses, and Surface Plasmon Polaritons (SPPs). In this example, we are showing how to use Setfos to optimize a prototypical top-emitting OLED (TEOLED) stack towards high light-outcoupling efficiency and thus EQE.
