Experimental investigation on photothermal conversion properties of lampblack ink nanofluids

Preparation and performance of anti-icing and deicing PF-POS@SiO2/CB photothermal superhydrophobic coatings for electrical insulators

“…It can be clearly observed that the superhydrophobic SiO 2 /CB coating exhibits excellent light absorption performance in a wide wavelength range, with its light absorption within 250 to 2500 nm essentially higher than 90%. This is attributed to the good light absorption capability of carbon black 37 and the used hierarchical micro/nanostructures with light trapping capability. 38 The excellent light absorption facilitates the conversion of more solar energy into thermal energy by the coating.…”

Modeling of the synergistic anti-reflection effect in gradient refractive index films integrated with subwavelength structures for photothermal conversion

“…For PU/MCS, the photothermal conversion efficiency can be denoted as: 69 where c and m represent specific heat capacity and the mass of PU/MCS, respectively. Δ T represents the temperature rise of the material.…”

Numerical Study of Thermal Performance Influence on Design Parameter and Fe3O4 Nanofluid of Flat Plate Direct Absorption Solar Collector

“…Therefore, the direct absorption solar thermal collecting method has the advantage that heat loss could be minimized, and solar thermal conversion efficiency is high [11]. However, some studies have been carried out through the dispersion of plasmonic [12][13][14][15][16][17], metal oxide [18][19][20][21][22], and nonmetallic NPs (nanoparticles) [23][24][25][26][27][28][29] for the direct absorption solar thermal collecting method because working fluids, such as water, antifreeze, and oil, generally used in the solar collector [30], possess large optical transmittance. The beneficial aspect of using NF for the direct absorption solar thermal collecting method is that it can improve both the heat transfer performance of the working fluid and the optical absorption performance [31,32].…”
