摘要： 本实验是针对本科生能力水平、结合光伏领域前沿设计的一个化学综合实验。本实验采用简单的旋涂法在导电玻璃表面制备CsPbBr3钙钛矿薄膜材料，并创新性地将光探测器件的组装实验加入其中以研究CsPbBr3薄膜的光电性能。学生可在实验过程中肉眼可见地观察到黄色的CsPbBr3材料在紫外激光照射下发射出强烈的绿光，这一实验现象能够有效地激发学生兴趣。

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.
