“…At the same time, materials need to be conceived to have the lowest radiative and convective losses that reduce the thermal efficiency of the receivers, to retain their structural integrity after thousands of thermal cycles, and to protect the structural component from external factors (erosion, action of wind, dust, hail, etc.). Ceramics, metals, and combinations of both are currently employed as solar selective coatings [17][18][19].…”

Solar power is a sustainable and affordable source of energy, and has gained interest from academies, companies, and government institutions as a potential and efficient alternative for next-generation energy production. To promote the penetration of solar power in the energy market, solar-generated electricity needs to be cost-competitive with fossil fuels and other renewables. Development of new materials for solar absorbers able to collect a higher fraction of solar radiation and work at higher temperatures, together with improved design of thermal energy storage systems and components, have been addressed as strategies for increasing the efficiency of solar power plants, offering dispatchable energy and adapting the electricity production to the curve demand. Manufacturing of concentrating solar power components greatly affects their performance and durability and, thus, the global efficiency of solar power plants. The development of viable, sustainable, and efficient manufacturing procedures and processes became key aspects within the breakthrough strategies of solar power technologies. This paper provides an outlook on the application of thermal spray processes to produce selective solar absorbing coatings in solar tower receivers and high-temperature protective barriers as strategies to mitigate the corrosion of concentrating solar power and thermal energy storage components when exposed to aggressive media during service life.

“…To overcome these comprehensive problems, alternative nanofabrication techniques have been introduced [27][28][29][30][31][32] . However, the needs of high-temperature vacuum processing and/or plasma/chemical etching can still restrict the applicable materials, especially for flexible and organic-based devices 33,34 . In addition, such a lithographically defined MNP is typical of an 'embossed' structure on the substrate surface, which is prone to be damaged over time by external irritations, such as scratches and hard contacts, or internal degradations, such as cracks and delaminations [35][36][37] .…”

A facile and scalable lithography-free fabrication technique, named solution-processable electrode-material embedding in dynamically inscribed nanopatterns (SPEEDIN), is developed to produce highly durable electronics. SPEEDIN uniquely utilizes a single continuous flow-line manufacturing process comprised of dynamic nanoinscribing and metal nanoparticle solution coating with selective embedding. Nano- and/or micro-trenches are inscribed into arbitrary polymers, and then an Ag nanoparticle solution is dispersed, soft-baked, doctor-bladed, and hard-baked to embed Ag micro- and nanowire structures into the trenches. Compared to lithographically embossed metal structures, the embedded SPEEDIN architectures can achieve higher durability with comparable optical and electrical properties and are robust and power-efficient even under extreme stresses such as scratching and bending. As one tangible application of SPEEDIN, we demonstrate a flexible metal electrode that can operate at 5 V at temperatures up to 300 °C even under the influence of harsh external stimuli. SPEEDIN can be applied to the scalable fabrication of diverse flexible devices that are reliable for heavy-duty operation in harsh environments involving high temperatures, mechanical deformations, and chemical hazards.

“…Within the last decade, nanostructured metamaterials have become an attractive topic in the field of radiative heat transfer for thermal energy harvesting ( Bello and Shanmugan, 2020 ; Jin et al., 2016 ; Khodasevych et al., 2015 ; Woolf et al., 2018 ; Xu et al., 2020 ) and radiative cooling ( Raman et al., 2014 ; Zhai et al., 2017 ). For harvesting solar energy to heat, spectrally selective absorbers with high solar absorption and low infrared emission are highly desired for efficient energy conversion, and many metamaterial selective solar absorbers have been designed and experimentally demonstrated recently based on multilayer ( Chirumamilla et al., 2016 , 2019 ; Dyachenko et al., 2016 ; Khoza et al., 2019 ; Thomas et al., 2017 ; Wang et al., 2018 ), periodic tungsten convex or concave gratings ( Jae Lee et al., 2014 ; Wang et al., 2015 ; Wang and Wang, 2013 ), nickel nanopyramids and tungsten nanowires (WNWs)/doughnuts ( Behera and Joseph, 2017 ; Li et al., 2015 ; Tian et al., 2018 ), and nanoporous or nanoparticle composite structures ( Lu et al., 2016 , 2017 ; Prasad et al., 2018 ).…”

Enhancing solar-thermal energy conversion with silicon-cored tungsten nanowire selective metamaterial absorbers

Summary This work experimentally studies a silicon-cored tungsten nanowire selective metamaterial absorber to enhance solar-thermal energy harvesting. After conformally coating a thin tungsten layer about 40 nm thick, the metamaterial absorber exhibits almost the same total solar absorptance of 0.85 as the bare silicon nanowire stamp but with greatly reduced total emittance down to 0.18 for suppressing the infrared emission heat loss. The silicon-cored tungsten nanowire absorber achieves an experimental solar-thermal efficiency of 41% at 203°C during the laboratory-scale test with a stagnation temperature of 273°C under 6.3 suns. Without parasitic radiative losses from side and bottom surfaces, it is projected to reach 74% efficiency at the same temperature of 203°C with a stagnation temperature of 430°C for practical application, greatly outperforming the silicon nanowire and black absorbers. The results would facilitate the development of metamaterial selective absorbers at low cost for highly efficient solar-thermal energy systems.
