Organic Transport Model for Tandem Organic Light-Emitting Diode

Next generation displays are utilizing tandem organic light-emitting diode (OLED) topologies to improve panel performance. The operation of these devices depends on the physics of a charge generation layer which serves to connect the two OLEDs in series. Conventional device models are inadequate to capture the carrier transport involved. To remedy this, in this Simulation Standard, a new organic transport model in Victory Device is introduced. The model capabilities are highlighted by applying it to accurately describe transport in the Charge Generation layer.

We begin by reviewing the analytical model of carrier injection into organic semiconductors and advance to the newly developed organic transport model based on the theory of organic hopping transport. Furthermore, to simulate the electrical properties of OLEDs, the fundamental steps involve carrier injection and transport, governed by material parameters such as energy bands (HOMO, LUMO), mobility, and doping conditions.
