In contrast to a conventional single layer solar still, herein a multilayer system for solar light harvesting and water evaporation via transparent photothermal thin films is developed. Monodispersed Fe3O4@Cu2–xS nanoparticles are dispersed in a polymer solution and deposited on glass and quartz substrates as transparent thin films. These thin films are optically characterized with strong absorptions in the UV and NIR regions, and high average visible transmittance. The photon energies in the UV/NIR regions are converted to heat increasing the water evaporation rate, while the film high transparency makes it possible for light to pass through many layers for an enlarged solar harvesting surface area. A multilayer photothermal evaporation system (MPTES) is developed for water evaporation experiments using various photothermal films. Water evaporation rates are compared between Fe3O4@Cu2–xS and Fe3O4 against different numbers of layers in the MPTES. The photothermal and optical properties of Fe3O4@Cu2–xS thin films are correlated to the heating behaviors and saltwater evaporation rate. Due to high transparency and strong photothermal effects of the films, water evaporation is significantly enhanced via multilayers. The concept of the multilayer solar still will show promise in water desalination.

通过多层透明光热 Fe3O4@Cu2-xS 薄膜进行太阳能海水淡化
与传统的单层太阳能蒸馏器相比，这里开发了一种通过透明光热薄膜进行太阳能收集和水蒸发的多层系统。单分散 Fe 3 O 4 @Cu 2– xS 纳米粒子分散在聚合物溶液中，并以透明薄膜的形式沉积在玻璃和石英基板上。这些薄膜的光学特性是在紫外和近红外区域有很强的吸收，以及高平均可见光透射率。UV/NIR 区域中的光子能量被转化为热量，从而提高了水的蒸发率，而薄膜的高透明度使光能够穿过多层，从而扩大太阳能收集表面积。开发了一种多层光热蒸发系统 (MPTES)，用于使用各种光热膜的水蒸发实验。Fe 3 O 4 @Cu 2– x S 和 Fe 3 O 4之间的水分蒸发率比较针对 MPTES 中不同数量的层。Fe 3 O 4 @Cu 2– x S 薄膜的光热和光学特性与加热行为和盐水蒸发率相关。由于薄膜的高透明度和强光热效应，通过多层膜显着增强了水分蒸发。多层太阳能蒸馏器的概念将在海水淡化中显示出前景。
