Enhancing the analysis of external quantum efficiency in OLEDs utilizing thin transport layer materials

OLED technology, a revolutionary approach to display and lighting, offers thin, flexible, and vibrant solutions that redefine the visual experience in various devices. External quantum efficiency, a key metric, provides valuable insights into how effectively these devices convert electrical energy into light, guiding efforts to enhance efficiency and optimize OLED technology. This crucial factor, often affected by charge imbalance, non-radiative processes, energy losses, material limitations, device architecture, and design, can be significantly improved. The choice of material selection can impact the ability of the OLED to convert injected charges into light effectively. The transport layers facilitate the movement of charge carriers (electrons and holes) within the device, influencing light emission efficiency. In this proposed work, the introduction of organic materials in electron and hole transport layers can potentially improve the external quantum efficiency by up to 11.2%, a significant advancement that can be analyzed through electrical and optical characterization.
