水蒸汽的产生是许多领域的重要过程。将热局部化和薄膜蒸发相结合，提出了一种低成本、高效率的太阳能蒸汽发生器。测量结果表明，能量效率为78%，在1千瓦/米（2）。同时，实验结果与我们基于薄膜蒸发理论的理论预测相吻合。此外，还讨论了颗粒浓度和粒径对效率的影响。研究发现，发电机的性能与几种不同的颗粒（石墨、石墨烯、二硫化钼和碳纳米管）有很弱的相关性。这项工作提供了一个新的深入了解，高效的太阳能蒸汽发电，并显示了一个例子，使用纳米技术在实际应用中的一个廉价和简单的方式。
Generating water steam is a significant process for many fields. By combining heat localization and thin-film evaporation, a low-cost high-efficiency solar steam generator is proposed here. The measurements show that the energy efficiency is 78% at 1 kW/m(2). Meanwhile, the experimental results agree well with our theoretical prediction based on thin-film evaporation theory. Besides, the dependence of efficiency on particle concentration and size are discussed. It's found that the performance of the generator has a weak correlation to a few different particles (graphite, graphene, MoS2, and carbon nanotubes). This work offers a new in-depth understanding of high-efficiency solar steam generation and shows an example of using nanotechnology in practical application by a cheap and simple way.
