“…When we exclude the atmospheric absorption bands, the Sun's spectrum can be approximated to that of a black body with a temperature of 5778K. [23,24] Considering that the atmospheric absorption bands are very thin, and on the other hand, we need a continuous mathematical equation for multiplication and integration in the next step, so this approximation is completely acceptable. To determine this, we consider the distance from the Sun and use Planck's radiation law, [25][26] which is shown in equation (1), to calculate the spectral irradiance from a black body.…”

Metal nanoparticles (NPs) with subwavelength dimensions exhibit plasmonic phenomena in resonance frequency and can absorb a portion of light non-radiatively and thermally. This property of NPs can be used in various applications such as seawater desalination, where the thermal power generated by them can be utilized. In this paper, we have designed and analyzed NPs to achieve maximum absorption and heat generation under solar irradiance. The NPs were arranged on a glass substrate in the most optimal pattern to obtain the highest possible absorption and heat generation. We utilized a numerical method to determine the total absorbed power of the NPs under solar irradiance. The shape, material, size and arrangement and interaction of the NPs determine their optical behavior, and, as a result, their thermal behavior. Therefore, we designed cylindrical, cubic, triangular, and hexagram-shaped NPs with the same volume of metal, choosing the material from noble metals such as Ag, Au, Cu, and Al. In the first step, we calculated the absorption cross-section of NPs using the Finite Difference Time Domain (FDTD) method. We then multiplied the solar irradiance intensity by the cross-section obtained in the first step. In the final step, we integrated the graph obtained in the solar spectrum to obtain the total absorbed power of the NPs. To determine the best arrangement period of the NPs, we utilized the Particle Swarm Optimization (PSO) method. This algorithm helped us find the period with the highest absorbed power. Aluminum hexagram nanoparticles, having the highest absorbed power and cost-effectiveness in manufacturing, were considered as the main candidates for the structure.

Rational dynamic thermal regulation of both solar and thermal regions is of significant importance for building energy saving. In this work, an electro‐driven dynamic radiative thermal regulation material (EDRTRM) capable of switching the thermal regulation capacity between the heating, white cooling, and multicolored cooling (blue, green, and yellow) modes is designed. These multi‐modes with high thermal regulation power and color variation are achieved through a synergistic material combination involving an electrochromism of Prussian blue (PB) and the electrodeposition of copper (Cu) with a polyformaldehyde (POM)‐based mid‐infrared (MIR) emitter. Optical characterization confirmed the superior spectral performance of materials, with a remarkable modulation capability of power density up to 659 W m−2, indicating an exceptional heating and cooling performance, which is evidenced by a temperature modulation difference of up to 11 °C. Notably, the EDRTRM under a multi‐colored cooling mode also achieves a temperature reduction of ≈ 4–6 °C. The EnergyPlus simulations demonstrate that the EDRTRM can save a huge amount of energy consumption of 16.56 MJ m−2 in cities with seasonal temperature variations such as Beijing. This dual‐functional design not only maximizes thermal regulation capabilities but also satisfies aesthetic requirements, showcasing its potential for widespread practical application.
