Prediction and Simulation of electrical and optical characteristics of an OLED based on P3BEdotBT3A organic material

Abstract

The OLED “organic light-emitting diode” has been highly industrialized for several years, especially since their use in smartphones and televisions. OLEDs have attracted a lot of attention because of their desirable characteristics including their low consumption of electrical energy, their flexibility... Our work focuses on the simulation of a single-layer OLED based on an organic material (ITO/P3BEdotBT3A/Ca) using the SILVACO-TCAD simulation software. This simulation allowed us to visualize the operational distribution of Langevin recombination within the proposed structure, and to determine the electrical and optical characteristics, such as luminescence power, current versus electric field, and current versus voltage (the I-V characteristics) for different thicknesses and doping concentration of the emitting layer.
