Design, Simulation & Optimization on Electrical and Optical Parameters of Alq3 QW-OLED

Abstract

Although the light-emitting diode (LED) was discovered in the 1900s, it is now widely used in lighting, screens, and a variety of other indoor and outdoor applications. (Organic Light Emitting Diode) OLED is one of the advancing branches of LED technology. In the structure of Alq3 OLEDs, highlight-efficiency optical materials such as TPD (hole transport layer) and Alq3 (electron transport layer) have been used. Organic light emitting layers are between two electrical contacts. The anode was made of indium tin oxide (ITO), and the cathode was made of aluminiumlithium (Al/Li). This article reports the modelling and simulation of the Alq3 organic light-emitting diode (OLED) before and after applying quantum well (QW) using the general-purpose photovoltaic device model-GPVDM simulation. A reverse voltage of -2.24 V has been applied to the OLED. Light output current density variance curves have been obtained, as have the light flux and the current.
