Functional Radiative Cooling: Basic Concepts, Materials, and Best Practices in Measurements

Inorganic Multilayer Film with High Infrared Selective Emission Enhanced by SiNx for Daytime Radiative Cooling

“…It should be noted that our actual temperature measurements deviate from the ideal simulation due to various factors, such as the disparity in atmospheric transmittance, humidity, solar irradiance, thermal conductivity of the substrate, and the influence of nearby buildings and vegetation. Nevertheless, the multilayer film demonstrated a significant subenvironment cooling effect, which holds promising implications for DRC applications. , …”

Durable and Scalable Superhydrophobic Colored Composite Coating for Subambient Daytime Radiative Cooling

“…The energy consumption required for cooling increased continually with the growing global warming, which has further exacerbated the greenhouse effect and environmental issues. − An environmentally friendly cooling technique known as passive daytime radiative cooling − could cool objects by reflecting sunlight in the solar spectrum (0.3–2.5 μm) and by simultaneously radiating excessive heat by the atmospheric transparency window (8–13 μm) to the cold outer space spontaneously. , Numerous radiative cooling materials with exceptional solar reflectance and infrared emissivity − have been demonstrated, which show potential cooling applications in architecture, − personal thermal management, − photovoltaic modules, , water harvesting, , etc. However, the requirement for high reflectance of radiative cooling results in materials that are primarily white in color, which restricts the possibilities for practical applications.…”

An elliptical nanoantenna array plasmonic metasurface for efficient solar energy harvesting

“…Recently, several outstanding instances that have just been published in the literature demonstrate how metasurfaces may have a significant effect on a variety of nanoscale solar energy conversion processes (ESI section 1†). 10–12 Metasurfaces, optical antenna arrays with subwavelength dimensions, are potential candidates for converting photons to photons (such as radiative cooling systems), 13,14 as well as photons to phonons (thermal energy), 2 and photons to electrons, 15 due to their extraordinary interaction with light. The review article published recently by E. Cortés et al 2 presents a comprehensive discussion on metasurface applications in solar energy conversion.…”
