As time goes, the previous methods of designing radiative coolers are no longer viable due to the difficulty in achieving the desired performances. In this paper, the machine learning (ML) approach known as the Random Forest (RF) regression model is utilized to forecast and enhance the performance of a metasurface-based daytime radiative cooler. The proposed radiative cooler achieved an average absorptivity/emissivity of 99.69 % in the first atmospheric window (AW1) and 98.12 % in the second atmospheric window (AW2), with an Ultra-wide perfect absorption bandwidth of 19.9 μm. It is also estimated that the solar band has a reflection of 94.50 %. The Random Forest (RF) regression model has a Mean Absolute Percentage Error (MAPE) of 0.4955 %, which is far less than any other machine learning algorithms. Besides this, for better understanding of the absorption mechanism, the electric and magnetic fields distribution theory is investigated at different absorption peaks. Further the structure is polarization and incidence angle insensitive and show a good absorption performance even at larger angle of incidence. The proposed radiative cooler device got a net cooling power of 170.65 Wm<sup>-2</sup> at ambient temperature. This innovative method of enhancing the designing process might make the radiative cooler device considerably more precise.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"286 ","pages":"Article 113591"},"PeriodicalIF":6.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study explored the dynamics of droplet motion and critical dust carrying capacity, introduced a quantitative relationship between droplet volume and dust removal efficiency, systematically analyzed droplet dynamics and dust entrainment mechanism, and revealed three findings: (1) The dust carrying motion of the droplet exhibits two distinct motion stages, from accelerated linear motion to trailing state triggered by saturated dust capacity (4.8 mg, 5.9 mg, and 6.2 mg for 10, 30, 50 μL droplets).

However, the high energy consumption and heating costs in winter do not align with the requirements of green development. Therefore, in this study, a novel Composite Phase Change Material (CPCM) was developed to be integrated with a solar-air source heat pump swimming pool heating system. This system aims to provide longer heating durations and reduce temperature fluctuations, while also alleviating the pressure on national energy supply during peak energy consumption. Glycine (Gly) and potassium chloride (KCl) were combined with sodium acetate trihydrate (SAT) to prepare a shape-stabilized CPCM (SAT- Gly- KCl CPCM). It was integrated into a swimming pool heating system to justify the impact of the new material. Experimental results have demonstrated some major properties of this material, the melting point, latent heat value and supercooling degree were 40.3 °C, 274.4 J/g and 1.36 °C for the laboratory preparation, and 40.9 °C, 249.5 J/g and 1.42 °C for the large-scale preparation, respectively. The material also exhibited good stability and thermal reliability. When SAT-Gly-KCl CPCM was applied to a swimming pool heating system, it was found that 100 and 200 phase change thermal storage modules increased heating durations by 9.89 and 10.59 times, respectively, compared to the control group. Therefore, the SAT-Gly-KCl CPCM presents a promising solution for swimming pool heating systems.

Polymer coating based on the Mie scattering effect has been widely developed for efficient daytime radiative cooling due to its scalable potential. However, current studies mainly concentrate on the properties of a single scattering interface, neglecting the potential synergistic effects among multiple scattering interfaces. Consequently, we develop a multi-interface porous radiative cooling coating (MIPRC coating) for efficient sub-ambient radiative cooling relying on the emulsion templating method. MIPRC coating consists of three kinds of interfaces with refractive index gradient for photon scattering, including air/polymer, SiO<sub>2</sub> particle/polymer, and air/SiO<sub>2</sub> particle, resulting in a high solar reflectivity of 97.6 % and an emissivity of 0.964 within the atmospheric window. In radiative cooling experiments, the MIPRC coating achieved a minimum temperature reduction of 5.0 °C below ambient during daytime, and a maximum temperature reduction of 16.0 °C below ambient at nighttime. The corresponding maximum radiative cooling power reached 61.0 W m<sup>−2</sup> during the day and 105.5 W m<sup>−2</sup> at night. When the MIPRC coating is applied to a foam roof and exposed to ambient air, a roof temperature of 1.2 °C below the ambient under an average solar irradiance of 900W·m<sup>−2</sup> is achieved. Building energy-saving measures within 25.8 %–84.6 % can be achieved by applying MIPRC coating in Haikou, Nairobi, Singapore, Miami, and Hawaii.
