Abstract: In recent years, research in organic electronics, a burgeoning interdisciplinary field, has seen significant growth. Organic electronics aims to use organic materials to manufacture more flexible, environmentally friendly, and cost-effective electronic devices for applications in display technology, optoelectronics, energy conversion, and other fields. To enhance undergraduate students’ understanding of organic electronics, this experimental teaching plan centers on the commonly used organic polymer P3HT. Using a spin coater, students prepare and modify active layers, then characterize the surface morphology of these films with a step profiler, optical microscope, and atomic force microscope. Conductivity testing of the devices is performed using a probe station. Comprehensive and standardized protective measures ensure safety throughout the experimental process. Additionally, the experiment incorporates fundamental techniques and the use of various instruments, fostering students’ practical skills and scientific literacy. This experiment aims to ignite undergraduates’ interest in the forefront of organic electronics through hands-on preparation, modification, and characterization of organic polymer films, thereby enhancing their innovative thinking and overall competencies.
