Interfacial solar vapor generation has recently drawn much attention because of its high solar-to-vapor generation efficiency. Here we introduce the basic experimental procedures and analysis for undergraduates to perform such an experiment to catch up with the cutting-edge research wave. Interfacial solar vapor generation employs an interfacial solar vapor generator to localize the solar harvest and the vapor generation process at the air–water interface. In the experiment, three commonly seen black materials, namely, a black trash bag, carbon fabric, and black packing polyester, are used as the basic starting materials for the construction of solar vapor generators. The light absorption properties are measured with UV–vis spectroscopy, and the solar vapor generation efficiencies are obtained using the data collected with an electronic balance and thermometers. Overall, this experiment aims to introduce undergraduate students in chemistry, environmental science, textiles, geoscience, materials science, or engineering to a cutting-edge technology in solar energy conversion, environmental protection, and clean water access.

界面太阳蒸气产生：将学生介绍给实验程序和分析，以在空气-水界面处有效地收集能量并产生蒸气

界面太阳蒸气的产生由于其高的太阳蒸气产生效率而最近引起了很多关注。在这里，我们介绍了基本的实验程序和为学生进行此类实验的分析，以赶上前沿的研究浪潮。界面太阳蒸气的产生采用界面太阳蒸气的产生器来定位太阳能收集和气-水界面处的蒸气产生过程。在实验中，三种常见的黑色材料，即黑色垃圾袋，碳纤维和黑色填充聚酯，被用作制造太阳能蒸汽发生器的基本原料。用紫外可见光谱法测量光吸收特性，并使用电子天平和温度计收集的数据获得太阳蒸气的产生效率。总体而言，该实验旨在向化学，环境科学，纺织，地球科学，材料科学或工程学的本科生介绍太阳能转化，环境保护和清洁水利用方面的前沿技术。
