Abstract

Abstract: Perovskite light-emitting diodes (LEDs) have emerged as a promising next-generation display technology, demonstrating breakthrough advancements in both luminous efficiency and stability, with potential applications in ultra-high-definition, flexible, and wearable displays. Guided by the principle of integrating cutting-edge research into teaching, this study presents a comprehensive perovskite LED experiment centered on hole transport layer modulation, investigating the effects of charge transport layers on perovskite crystallization kinetics, carrier transport properties, and luminescence efficiency. The experimental design incorporates a complete teaching module encompassing “material preparation-device integration-performance characterization”. This approach not only enables students to acquire essential experimental skills—including literature review, material synthesis, device fabrication, structural characterization, and optoelectronic performance testing—but also deepens their understanding of device physics in perovskite LEDs, thereby effectively enhancing their innovative thinking and engineering practice capabilities.

Key words: Innovative experimental design, Perovskite, Light-emitting diode, Hole transport layer, Crystalline properties
