“…Solar absorptance (α) is broadly defined as a weighted fraction between absorbed radiation and incoming solar radiation (I sol ), while thermal emittance (ε) is defined as a weighted fraction between the emitted radiation and the Planck black body distribution (I p ), and both can be determined in terms of the surface reflectance (R(λ)) using the following equations [26,53]:…”

“…The type of matrix also influences the quality of the film. In this regard, a porous matrix is the optimum host for metal particle inclusion [6,26,46,91,95]. The surface morphology of cermet also plays a significant role in determining the surface absorptance and can favor multiple reflections in the surface, thus enhancing the solar radiation absorption [12].…”

“…Electroplating/electrochemical deposition (including chemical conversion/chemical bath deposition (CBD)) [17][18][19][20], vacuum deposition (physical vapor deposition (PVD)/sputtering) [8,21,22], chemical vapor deposition (CVD) [8,23], mechanical grinding [11], and sol-gel methods [24][25][26] are some of the methods that have been used to synthesize the absorber coatings, but only a handful of these have been applied on an industrial scale [27].…”

“…However, the application of these techniques to produce SSA materials is much less common than electrochemical or vacuum-based techniques. The sol-gel methods are wellknown simple, low cost, and environmentally friendly thin film fabrication techniques resulting in a uniform chemical thin film composition [26,44]. The sol-gel processes are a soft chemistry technique where the precursors are generally in the form of a colloidal-based solution that eventually 'transforms' into an widespread network of either discrete or continuously linked molecules.…”

“…The synthesis processes are low in material consumption and can be manufactured under ambient pressure [25,46]. It had been proved that the sol-gel method was able to reduce production costs drastically for absorber thin film fabrication compared to the sputtering method, because the cost for the coating itself could be neglected compared to the substrate cost and that at least half of the raw material costs could be reduced [26]. In terms of energy application, the sol-gel processes do not need the vacuum condition.…”

Global energy and environmental problems are becoming increasingly prominent, and the shortage of freshwater resources has been plaguing many countries and regions in the world. Solar steam generation (SSG) has emerged as a green, low‐cost and efficient strategy for freshwater production, which has attracted enormous attention in recent years. Furthermore, various photothermal materials and structural designs for the preparation of efficient SSG systems have been widely reported. Among them, metal‐based photothermal materials are abundant, and the exploration on metal‐based SSG systems is one of the important research directions. In this review, the basic concepts and design objectives of current metal‐based SSG systems are first introduced, as well as advances in the recent development of metal‐based photothermal materials, including photothermal mechanisms, and preparation methods. The evaluation criteria of the SSG system are further described. Then the development of metal‐based SSG systems is summarized in terms of structural design, functional modules (light absorption, thermal management, water transport, salt rejection, etc.), and potential applications (wastewater treatment, sterilization and other fields). Finally, the main challenges and future prospects of metal‐based SSG systems in basic research and practical applications are emphasized.

 ε 100 C of 4-10%, as well as thermal stability below 500 °C, [9,10,14-17] which can hardly satisfy the requirements of Low-cost and large-area solar-thermal absorbers with superior spectral selectivity and excellent thermal stability are vital for efficient and large-scale solar-thermal conversion applications, such as space heating, desalination, ice mitigation, photothermal catalysis, and concentrating solar power. Few state-of-the-art selective absorbers are qualified for both low-(<200 °C) and high-temperature (>600 °C) applications due to insufficient spectral selectivity or thermal stability over a wide temperature range. Here, a high-performance plasmonic metamaterial selective absorber is developed by facile solutionbased processes via assembling an ultrathin (≈120 nm) titanium nitride (TiN) nanoparticle film on a TiN mirror. Enabled by the synergetic in-plane plasmon and out-of-plane Fabry-Pérot resonances, the all-ceramic plasmonic metamaterial simultaneously achieves high, full-spectrum solar absorption (95%), low mid-IR emission (3% at 100 °C), and excellent stability over a temperature range of 100-727 °C, even outperforming most vacuum-deposited absorbers at their specific operating temperatures. The competitive performance of the solution-processed absorber is accompanied by a significant cost reduction compared with vacuum-deposited absorbers. All these merits render it a cost-effective, universal solution to offering high efficiency (89-93%) for both low-and high-temperature solar-thermal applications.
