Abstract: The development of novel photovoltaic devices constitutes a crucial technological approach for achieving China's Dual Carbon Goals (Carbon Peak and Carbon Neutrality Policy). This comprehensive chemical experiment introduces organic solar cells (OSCs) utilizing fully non-fused ring electron acceptors (NFREAs). Through systematic comparison with fused-ring electron acceptor (FREA)-based devices in terms of power conversion efficiency, material cost, and operational stability, the experiment demonstrates the practical advantages of NFREA structures. Integrating device fabrication, performance characterization, stability assessment, and cost analysis into a modular teaching framework, this experiment overcomes the traditional emphasis on performance metrics while neglecting cost considerations. By transforming cutting-edge research into instructional experiments, this approach not only exposes students to frontier scientific developments and green chemistry principles, but also cultivates innovative thinking, cost awareness, and comprehensive practical skills - thereby laying a foundation for talent development in the renewable energy sector.
