摘要：

面向中国“双碳”目标的战略需求，发展新型的低成本高性能的光伏电池至关重要。本文介绍了新型反式结构钙钛矿光伏电池的制备过程及其相关的性能表征，推荐其作为一个综合化学设计性实验，提高本科生的科技创新及综合实践能力。该实验包括反式钙钛矿光伏电池的制备流程，包括电极传输层、钙钛矿薄膜和电极层的制备。用扫描电子显微镜及X射线衍射仪研究钙钛矿薄膜的形貌及结晶质量表征，随后通过太阳光模拟器对电池的电流密度与电压(J–V)特性曲线及标准太阳光照稳定性测试。本实验集薄膜制备、材料表征及电池性能测试为一体，满足不同的教学需求，同时对实验涉及的化学原理进行讲授，方便学生对实验进行拓展，为今后的课外科技研究提供重要的基础。

Abstract:

The development of low-cost and high-performance solar cells has become an important direction for the "dual carbon strategy". In this manuscript, we mainly describe the fabrication and characterization of novel inverted perovskite solar cells as well as a comprehensive chemistry experiment for undergraduates conceived to promote their scientific innovation and comprehensive practical abilities. This experiment encompasses the fabrication process of inverted perovskite solar cells, including transport layer fabrication, perovskite film, and electrode. The morphology and crystal quality of perovskite films were characterized by scanning electron microscope and X-ray diffractometer, and the current density and voltage (J–V) curves and photostability of the devices were tested using a solar simulator. The proposed experiment also integrates film preparation, material characterization, and device performance testing to meet different teaching needs. Simultaneously, the basic chemical principles in the experiment are taught to encourage students to further expand the experiment and provide a solid foundation for their future research and exploration.
