Abstract

Opto-electronic devices exhibit highly nonlinear current–voltage (I–V) characteristics that significantly affect charge injection, transport, and recombination, evaluating their performance remains a difficult challenge. Device optimization is a key research goal in organic light-emitting diodes (OLEDs), as the thickness and arrangement of individual functional layers greatly influence electrical and optical responses. For a suggested Bebq2/BCP-based OLED structure, this work methodically examines the movement of charge carriers, their transport behavior, and the operating parameters necessary for maximal radiative recombination. Reducing the thickness of conducting layers while maintaining a low driving voltage and effective carrier balancing is given special consideration. While insufficient layer thickness can impair charge confinement and light production, excessive layer thickness can increase resistance and power consumption. Finding the ideal structural characteristics is therefore crucial to enhancing device performance. The nature-inspired Salp Swarm Optimization (SSA) method is used as an efficient computational tool for structure optimization and parameter extraction to overcome this difficulty. To optimize brightness and minimize voltage requirements, the SSA approach effectively searches the design space to find appropriate combinations of layer thicknesses and operational parameters. According to simulation results, the optimized OLED structure outperforms non- optimized designs in brightness, total layer thickness, carrier recombination efficiency, and operating voltage. These advancements show that clever optimization strategies can overcome the drawbacks of traditional trial- and-error design approaches. As a result, the suggested SSA-based optimization strategy is useful for the future development of high-performance optoelectronic devices as it provides a dependable and effective method for predicting OLED parameters and enhancing overall device efficiency.

Keywords: OLED, SSA, HOMO and LUMO energy level, PSO, luminance.
