Abstract

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.

利用薄传输层材料加强对有机发光二极管外部量子效率的分析

OLED 技术是一种革命性的显示和照明方法，它提供了轻薄、灵活、生动的解决方案，重新定义了各种设备的视觉体验。外部量子效率是一项关键指标，它为了解这些设备如何有效地将电能转化为光能提供了宝贵的见解，为提高效率和优化 OLED 技术提供了指导。这一关键因素往往受到电荷不平衡、非辐射过程、能量损失、材料限制、器件结构和设计的影响，因此可以得到显著改善。材料的选择会影响有机发光二极管将注入电荷有效转化为光的能力。传输层可促进电荷载流子（电子和空穴）在器件内的移动，从而影响光发射效率。在这项拟议的工作中，在电子和空穴传输层中引入有机材料有可能将外部量子效率提高 11.2%，这一重大进步可通过电学和光学特性分析得出。

期刊介绍： he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
