Abstract: This experiment is a comprehensive chemistry experiment designed for undergraduate students’ ability level and integrated with the forefront of the photovoltaic field. A simple spin-coating method is used to prepare CsPbBr₃ perovskite thin films on conductive glass surfaces. The assembly experiment of photodetector devices is incorporated to study the optical and photoelectric properties of CsPbBr₃. Students can visually observe the intense green light emitted by the yellow CsPbBr₃ material under UV laser irradiation, effectively stimulating their interest.

Key words: Perovskite CsPbBr₃, Photoluminescence, Photovoltaic conversion, Photo current
