چکیده :

Abstract In today's world, achieving technologies that not only have advanced technical and specialized quality but also consume less energy and have lower detrimental environmental impact is of great importance. Due to recent environmental issues and energy supply conditions, the need to use and replace energy-efficient and environmentally friendly light sources has led to a significant amount of research efforts in this field. In this article, we aim to discuss the positive effects of using organic materials, improve and reduce energy consumption, as well as enhance electronic and optical efficiency and the compatibility of these organic materials with nature. Additionally, we will explore the use of OLED technology instead of LED. Organic diodes have been the subject of extensive research in recent years due to their potential applications in various optoelectronic devices. However, their performance is highly dependent on their structural design and optimization. In this study, we propose a novel approach for designing and optimizing the structure of organic diodes using numerical simulation and multi-objective optimization methods. We employed a numerical simulation tool to investigate the effect of various structural parameters on the performance of the organic diodes, including the thickness of the organic layers and the electrode materials. We then used a multi-objective optimization algorithm to find the optimal combination of structural parameters that simultaneously maximize the diode's efficiency, reduce its turn-on voltage, and minimize its series resistance. Our results demonstrate that the proposed approach can effectively improve the performance of organic diodes by achieving a trade-off among the different optimization objectives. We show that the optimized structure of the organic diode can significantly enhance its performance by reducing the turn-on voltage by 20%, increasing the efficiency by 15%, and decreasing the series resistance by 10%. In conclusion, our study provides a practical approach for designing and optimizing the structure of organic diodes using numerical simulation and multi-objective optimization methods, which can lead to the development of more efficient and high-performance optoelectronic devices.
