Passive radiative cooling (PRC) is a zero-energy-consumption technology that reflects sunlight and radiates heat to cold outer space. In this work, porous poly(vinylidene fluoride)–poly(methyl methacrylate) (PVDF–PMMA) composite film fabricated by decorating zinc-imidazolate metal–organic framework (MOF) (ZIF-8) particles obtained phase inversion. Due the competent scattering via coral-like hierarchical structures vibration excitations of specific functional groups, prepared exhibits good...
Passive radiative cooling is a spontaneous pattern of reflecting sunlight and radiating heat into the cold outer space through transparent atmosphere windows. In this work, an ordered-porous-array polymethyl methacrylate (OPA-PMMA) film with properties excellent designed studied. An ultra-high emissivity 98.4% in mid-infrared region (3-25 μm) good solar reflectance 85% ultraviolet near-infrared spectra (0.2-2.5 were achieved. The surface temperature OPA-PMMA 16 °C lower than that...
Characterizing the electrical parameters of perovskite solar cells (PSCs) usually requires a lot time to fabricate complete devices. Here, machine learning (ML) is used reduce device fabrication process and predict performance PSCs. Using ML algorithms 814 valid data cleaned from 2735 peer‐reviewed publications, prediction models are built for bandgap, conduction band minimum, valence maximum perovskites, These have excellent accuracy, root mean square error bandgap power conversion...
Passive daytime radiative cooling (PDRC) as a zero-energy consumption method has broad application potential. Common commercial crystalline silicon (c-Si) solar cell arrays suffer working efficiency loss due to the incident light and overheating. In this work, cooler with PDMS (polydimethylsiloxane) film embedded SiO2 microparticles was proposed use in cells. Both anti-reflection performance can be improved through numerical parametric study. For best performing of PDMS/SiO2 cooler,...
Ultrathin crystalline silicon solar cells are a promising technology roadmap to achieve more cost effectiveness. However, experimental reports on ultrathin with thickness less than 20 µm rare. Here, we experimentally fabricate and investigate monocrystalline consisting of 16 µm-silicon base low-cost front random pyramidal texture the feature size 1-2 µm. The normalized light absorption is calculated explain measured external quantum efficiency. achieved efficiency 15.1% for single-layer...
Mechanically robust superhydrophobic (SHP) and icephobic performances are highly needed for an anti-icing surface in practical applications. Here, a SHP coating is prepared on the aluminium (Al) substrate using hydrothermal reaction subsequent modification of hexadecyltrimethoxysilane, showing water contact angle larger than 158° sliding (SA) less 5°. This displays hydrophobic performance acidic or alkaline solutions, after sand abrasion consecutive icing/deicing cycles. It largely reduces...
