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.
