摘要： 柔性有机太阳能电池因其轻量化、可弯曲和低温溶液加工等优势，在可穿戴电子与分布式能源领域展现出广阔应用前景，同时也是新能源材料与器件教学的重要前沿方向。然而，现有本科实验课程中柔性有机太阳能电池相关内容较为匮乏，难以满足学生对前沿技术与工程实践的学习需求。针对上述问题，本文以柔性有机太阳能电池的制备与表征为载体，开发了一套面向本科生的综合性实验教学模块。该实验围绕柔性透明电极与器件性能之间的结构–性能关系，设计并比较了PET (polyethylene terephthalate) /ITO (Indium tin oxide)、PET/AgNWs (silver nanowires)与半嵌入式PI (polyimide) @AgNWs三种典型电极体系，引导学生系统完成电极制备与表征、柔性器件构筑、光伏性能测试以及机械弯曲性能定性评估。结果表明，半嵌入式PI@AgNWs电极在保持良好导电性能的同时显著降低表面粗糙度(均方根粗糙度低至0.56 nm)，并明显提升器件的弯曲与服役稳定性，相关实验结果具有良好的重复性和教学可操作性。通过完整的“制备–表征–评价–展示”实验流程，学生能够深化对“基底–电极–器件性能”耦合关系的理解，有效提升工程实践能力、数据分析能力与创新意识。该实验教学改革为新能源材料与器件相关课程的研究性、工程化和综合化建设提供了可借鉴的实践范式。

Abstract: Flexible organic solar cells (FOSCs) have garnered increasing attention owing to their lightweight design, mechanical flexibility, and low-temperature solution processability, demonstrating significant potential for applications in wearable electronics and distributed energy systems. As a key frontier topic in new energy materials and devices education, FOSCs remain underrepresented in current undergraduate laboratory curricula, failing to adequately address students’ learning needs for cutting-edge technologies and engineering practice. To bridge this gap, this study employs the fabrication and characterization of flexible organic solar cells as a pedagogical framework to develop a comprehensive experimental teaching module for undergraduates. Focusing on the structure–property relationships between flexible transparent electrodes and device performance, three representative electrode systems—PET/ITO, PET/AgNWs, and semi-embedded PI@AgNWs—are designed and comparatively investigated. Students are guided through a systematic workflow encompassing electrode fabrication and characterization, flexible device assembly, photovoltaic performance testing, and qualitative mechanical bending evaluation. Results indicate that the semi-embedded PI@AgNWs electrode substantially reduces surface roughness (with a root-mean-square roughness as low as 0.56 nm) while maintaining excellent conductivity, significantly improving device bending tolerance and operational stability. The experimental outcomes demonstrate high reproducibility and strong feasibility for instructional implementation. Through the integrated “fabrication-characterization-evaluation-demonstration” workflow, students gain deeper insights into the coupling effects of substrate, electrode, and device performance while enhancing their engineering practice skills, data analysis capabilities, and innovative thinking. This teaching reform offers a practical and transferable model for advancing research-oriented, engineering-focused, and comprehensive laboratory courses in new energy materials and devices.
