Abstract

The reversible transformation of radiative cooling and solar heating of the film is significant for a building's energy conservation and carbon emission reduction. The current technology is constrained by its reliance on complex control mechanisms and a narrow control scope, which collectively impede its practical deployment. In this Letter, we introduce an all-season smart film, a multilayer film composed of In3SbTe2 (IST), CaF2, and ZnS on an Al substrate, which possesses the unique ability to synergistically modulate solar-thermal radiation. The solar absorptance and infrared emittance are (anormal, εnormal) = (0.829, 0.055) for the solar heating mode and (0.361, 0.835) for the radiative cooling mode, respectively. The underlying mechanism pertains to the Fabry–Pérot resonance and antireflection. The modulation property of the smart film remains excellent even when the incident angle is large. Furthermore, the smart film is capable of achieving multilevel modulation through the alteration of the crystalline IST percentage. The excellent modulation properties of the smart film are substantiated through a quantitative assessment of the net heat flux for terrestrial applications. This analysis reveals that the smart film with amorphous IST achieves a solar heating flux of 800 W/m2 at 250 K, while for crystalline IST it exhibits a radiative cooling flux of 600 W/m2 at 330 K. Such a simple multilayer structure can be easily fabricated, which would facilitate the advancement and practical implementation of an all-season smart film.

基于in3sbte2的太阳能和热辐射协同调制的全季节智能薄膜

地膜的辐射制冷和太阳能加热的可逆转化对建筑节能减排具有重要意义。目前的技术受限于依赖复杂的控制机制和狭窄的控制范围，这些共同阻碍了其实际部署。在这篇论文中，我们介绍了一种全季节智能薄膜，一种在Al衬底上由In3SbTe2 （IST）、CaF2和ZnS组成的多层薄膜，它具有独特的协同调节太阳热辐射的能力。太阳加热模式的太阳吸收率和红外发射率(εnormal) =(0.829, 0.055)，辐射冷却模式的太阳吸收率和红外发射率（0.361,0.835）。其基本机制与法布里-帕氏共振和抗反射有关。即使在入射角较大的情况下，智能薄膜的调制性能仍保持良好。此外，该智能薄膜能够通过改变晶体IST百分比实现多电平调制。通过对地面应用的净热通量的定量评估，证实了智能薄膜的优异调制特性。分析结果表明，非晶IST智能膜在250 K时的太阳加热通量为800 W/m2，而晶体IST在330 K时的辐射冷却通量为600 W/m2。这种简单的多层结构可以很容易地制作，这将促进全季节智能薄膜的进步和实际实施。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
