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CsPbBr_(3)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CsPbBr_(3)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CsPbBr_(3)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。
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 CsPbBr_(3) perovskite thin films on conductive glass surfaces.The assembly experiment of photodetector devices is incorporated to study the optical and photoelectric properties of CsPbBr_(3).Students can visually observe the intense green light emitted by the yellow CsPbBr_(3) material under UV laser irradiation,effectively stimulating their interest.
