“…For instance, it has almost become a universal strategy to use plasmonic NPs with hybrid material designs, [131,132] wide-distributed sizes, [133,134] and/or various shapes [135] to achieve ultrabroadband absorption. These NPs supporting LSPs at selected wavelengths can be either suspended in solutions [136,137] or assembled on supporting substrates, [138,139] enabling ultrabroadband solar absorption and highly efficient photothermal conversion for targeted applications.…”

The indispensable requirement for sustainable development of human society has forced almost all countries to seek highly efficient and cost‐effective ways to harvest and convert solar energy. Though continuous progress has advanced, it remains a daunting challenge to achieve full‐spectrum solar absorption and maximize the conversion efficiency of sunlight. Recently, thermoplasmonics has emerged as a promising solution, which involves several beneficial effects including enhanced light absorption and scattering, generation and relaxation of hot carriers, as well as localized/collective heating, offering tremendous opportunities for optimized energy conversion. Besides, all these functionalities can be tailored via elaborated designs of materials and nanostructures. Here, first the fundamental physics governing thermoplasmonics is presented and then the strategies for both material selection and nanostructured designs toward more efficient energy conversion are summarized. Based on this, recent progress in thermoplasmonic applications including solar evaporation, photothermal chemistry, and thermophotovoltaic is reviewed. Finally, the corresponding challenges and prospects are discussed.

“…A combined PVT/PCM system using nanofluids has proved to be an effective coolant in enhancing the thermal conductivity of PVT collectors [202]. Other studies related to nanofluids in solar collectors investigated the photothermal properties of various mono and hybrid nanofluids [203][204][205][206][207][208][209][210][211][212], the impact of magnetic fields on the thermal performance of nanofluids in a solar collector [213], the forced convective behaviour of nanoparticles inside a solar collector [214] and more recently the application of ANN models for the prediction of nanofluids performance in solar collectors [215][216][217]. Other studies investigating the application of nanofluids in various solar collectors are presented in Table 7.…”

The field of nanofluids has received interesting attention since the concept of dispersing nanoscaled particles into a fluid was first introduced in the later part of the twentieth century. This is evident from the increased number of studies related to nanofluids published annually. The increasing attention on nanofluids is primarily due to their enhanced thermophysical properties and their ability to be incorporated into a wide range of thermal applications ranging from enhancing the effectiveness of heat exchangers used in industries to solar energy harvesting for renewable energy production. Owing to the increasing number of studies relating to nanofluids, there is a need for a holistic review of the progress and steps taken in 2019 concerning their application in heat transfer devices. This review takes a retrospective look at the year 2019 by reviewing the progress made in the area of nanofluids preparation and the applications of nanofluids in various heat transfer devices such as solar collectors, heat exchangers, refrigeration systems, radiators, thermal storage systems and electronic cooling. This review aims to update readers on recent progress while also highlighting the challenges and future of nanofluids as the next-generation heat transfer fluids. Finally, a conclusion on the merits and demerits of nanofluids is presented along with recommendations for future studies that would mobilise the rapid commercialisation of nanofluids.

“…Enhancement in PTE (95% over base fluid) was observed at 0.04wt%. Sharaf et al [72] investigated the optical characteristics of broadband absorbing polyethylene glycol (PEG) and trisodium citrate (CIT) based gold nanofluids with a focus on improving thermodynamic stability. The result shows that PEG-based gold nanofluids exhibited higher thermal stability and required less particle loading for better direct absorption.…”

The evolution of nanofluids over the years have opened new research opportunities in the field of renewable energy. Research on the optical properties of nanofluids for application in direct absorption solar collectors (DASCs) is progressing at a burgeoning speed. In a direct absorption solar collector system, nanofluid with high optical absorptivity will convert the incident solar energy to the thermal energy of the fluid. The dispersed nanoparticles in the fluid acts in the process by the phenomenon of absorption and scattering. Studies conducted on the optical property characterization of monocomponent nanofluids have become saturated. Moreover, the photothermal efficiency of the nanofluid could be enhanced by using multicomponent nanofluids. Nanofluid prepared by varying materials, shapes, and size of nanoparticles could tune the absorption spectra of the bulk fluid to improve the photothermal efficiency. A hybrid nanocomposite can similarly enhance the absorptivity due to the synergy of materials present in the nanocomposite particle. In this review, a comprehensive survey on the synthesis and optical characterization of different blended and hybrid nanocomposite nanofluids have been performed. Besides, works on different mono nanofluids that have been studied over the years have been reviewed.
