“…Although there are many reviews on SDID, they mostly focus on improving evaporation efficiency by optimizing the materials/devices for solar energy absorption, light‐to‐thermal conversion, and water transportation. [ 33–50 ] However, many current studies lack specific research on salt mitigation, which in turn greatly hindered the practical application of SDID.…”

Solar‐driven interfacial desalination (SDID), which is based on localized heating and interfacial evaporation, provides an opportunity for developing environmentally friendly and cost‐effective seawater thermal desalination. However, localized heating and rapidly generated interfacial steam may cause salt to accumulate on the evaporator's surface and block the channel of steam evaporation. Salt accumulation inevitably reduces the light absorption and service period of the solar absorber, resulting in a significant decrease in evaporation efficiency over time. Salt accumulation makes it difficult to produce SDID devices with high energy efficiency and long‐term stability for large‐scale use in remote poverty‐stricken areas. Therefore, the exploration of novel and effective strategies for addressing salt accumulation through both material design and structural engineering has attracted more attention in recent years. This review presents an overview of the state‐of‐the‐art advancements in salt‐resistant photothermal evaporation and discusses the critical issues for achieving salt mitigation SDID, focusing on the classification of salt mitigation strategies based on photothermal evaporation configurations, the basic mechanism of salt mitigation, and the architectural design of photothermal materials. Finally, the important challenges and prospects of SDID are discussed to providing a meaningful roadmap to efficient salt mitigation SDID.

“…[13] Since Tabor et al [14] put forward the concept of solar selective absorption coatings (SSACs) in 1964, various SSACs are exploited, such as intrinsic absorber coatings, [15] textured surface coatings, [16] multilayer interference stacks, [17] semiconductormetal tandem coatings, [18] and metal-cermet composite coatings. [19][20][21][22] The α of intrinsic absorber relies on materials intrinsic characteristics, such as interband transition, transition metals, depressed plasma frequencies, and so on; while other coatings depend on the structure to improve their inherent high absorption and low emission. [23] There are at least three limitations in these artificial SSACs: complex manufacturing process, high fabrication cost, and poor thermal stability.…”

Solar selective absorbers (SSAs) possess high sunlight absorption (300–2500 nm) and low infrared thermal radiative losses (2.5–25 μm), which are undoubtedly the best choice for photothermal conversion process, and SSAs have been widely used in concentrating solar power, solar water heating, and solar drying. Recently, to promote the realization of “double carbon” goal, SSAs have received widespread attentions, many emerging sustainable applications have been developed. In this review, the recent developments of SSAs and their latest sustainable applications in solar‐driven seawater desalination, multistage solar desalination, atmospheric water harvesting (AWH), wastewater treatment, solar thermophotovoltaics (STPVs), hybrid photovoltaic‐thermal (HPVT), solar‐thermoelectric generators (STEG), personal thermal management (PTM), photothermal catalysis, photothermal deicing, and photothermal sterilization, etc. are systematically summarized. Also, the challenges as well as future opportunities of SSAs are discussion. It is expected that this review will effectively complement the published comments on SSAs and provide more inspirations on sustainable applications of SSAs in the future.

“…[ 1 ] Myriad research efforts are devoted to harvesting solar energy around the world due to its inexhaustible supply and being almost pollution‐free preponderance, wherein the photothermal conversion technique captures extensive attention. [ 2 ] Solar selective absorber (SSA) plays a decisive role in utilizing sunlight into thermal energy, which requires high solar absorptance ( α > 90%) in the solar spectrum (0.3–2.5 μm) and low thermal emittance ( ε < 10%) in the infrared region (2.5–20 μm), accompanying with various emerging applications in the fields of evaporation, [ 3 ] anti‐icing, [ 4 ] medical sterilization, [ 5 ] photothermal catalysis, [ 6 ] solar‐thermal power, [ 7 ] and solar thermoelectric generators. [ 8 ] When the concentration ratio is low, such as under 1 sun, a high spectral selectivity ( α / ε ) is crucial to photothermal conversion efficiency, which is especially suitable for moderate and low temperatures photothermal conversion systems.…”

Spectrally selective absorber with superior thermal stability and optical properties is crucial for photothermal conversion applications, including evaporation, anti‐icing, medical sterilization, photothermal catalysis, and solar‐thermal power. Efforts are being made to develop entropy‐stabilized high‐entropy ceramics as high‐performance functional materials, which promise a wide range of potential applications in the fields of energy storage and conversion owing to their diverse compositions and outstanding physical and chemical properties. Herein, an entropy‐stabilized strategy is used to boost the performance of spectrally selective absorbers by carefully choosing a high‐entropy alloy (TiVCrAlZr) target with a reasonable element design, which exhibits a good solar absorptance (α = 96.1%) and low thermal emittance (ϵ = 7.8%). Long‐term thermal stability investigation demonstrates that the entropy‐stabilized absorber could endure at 400 °C for 168 h. Under the irradiation of simulated sunlight, the surface temperature of the absorber can reach up to 105 °C, which is essential for middle‐ and low‐temperature applications. Overall, this work provides significant insights into the spectral selectivity of high‐entropy alloy nitrides and offers a new strategy for designing and developing moderate and low solar selective absorbing coatings via a high‐entropy strategy.
