Abstract

The research aims to assess the performance of organic light-emitting diodes (OLEDs) by exploring how various anode materials affect their optoelectronic properties. OLEDs are crucial for modern displays and lighting, and their efficiency and functionality are heavily influenced by the materials used in their design.This study examines four different anode materials: Indium Tin Oxide (ITO), Zinc Oxide (ZnO), Aluminum-doped Zinc Oxide (AZO), and Poly(3,4-ethylenedioxythiophene) Polystyrene Sulfonate (PEDOT: PSS). These materials are evaluated within OLED structures using the Silvaco ATLAS simulation tool, which provides a detailed analysis of their properties and performance.The OLEDs used in this research have a consistent emissive layer made of MEH-PPV (poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]) polymer and a fixed cathode. By keeping these components constant, the study isolates the impact of the different anode materials on the overall device performance.The findings reveal that the anode material’s work function is crucial to OLED performance. Notably, PEDOT: PSS, with its high work function, exhibits superior performance by improving the OLEDs’ luminescence and lowering the turn-on voltage, which is the minimum voltage required for the device to emit light. Overall, the study underscores the significance of choosing anode materials with high work functions to enhance OLED performance. By prioritizing these materials, manufacturers can produce OLEDs that offer greater brightness, reduced power consumption, and increased efficiency, all of which are essential for both display and lighting applications
