Interfacial solar steam generation is a highly efficient and sustainable technology for clean water production wastewater treatment. Although great progress has been achieved in improving evaporation rate energy efficiency, it's still challenging to fully eliminate the loss surrounding environment during generation. To achieve this, novel heatsink-like evaporator (HSE) developed herein. During evaporation, temperature on top surface can be regulated by fin structures of HSE. For evaporators with 5 7 heatsink fins, decreased lower than ambient temperature, which eliminates radiation, convection, conduction heat losses, leading absolute cold over entire under 1.0 sun irradiation. As result, massive (4.26 W), 170% received light energy, harvested from due deficit, significantly enhancing efficiency An extremely high 4.10 kg m-2 h-1 realized 6-fin photothermal HSE, corresponding an conversion far beyond theoretical limit, assuming 100% light-to-vapor conversion.

Abstract Solar‐driven interfacial evaporation is an emerging technology with a strong potential for applications in water distillation and desalination. However, the high‐cost, complex fabrication, leaching, disposal of synthetic materials remain major roadblocks toward large‐scale applications. Herein, benefits offered by renewable bacterial cellulose (BC) are considered all‐cellulose‐based steam generator developed. In this monolithic design, three BC‐based aerogels fabricated integrated to endow 3D well‐defined hybrid structures several self‐contained properties lightweight, efficient evaporation, good durability. Under 1 sun, delivers high rates 1.82 4.32 kg m −2 h −1 under calm light air conditions, respectively. These results among best‐performing generators, surpass majority devices constructed from other biopolymers. Importantly, first example integrating solar‐driven wave detection also demonstrated introducing self‐powered triboelectric nanogenerator (TENG). This work highlights developing biopolymer‐based, eco‐friendly, durable not merely scaling up sustainable clean production, but discovering new functions detecting parameters surface water.

Recent advances in thermally localized solar evaporation hold significant promise for vapor generation, seawater desalination, wastewater treatment, and medical sterilization. However, salt accumulation is one of the key bottlenecks reliable adoption. Here, we demonstrate highly efficient (>80% solar-to-vapor conversion efficiency) rejecting (20 weight % salinity) by engineering fluidic flow a wick-free confined water layer. With mechanistic modeling experimental characterization transport, show that natural convection can be triggered water. More notably, there exists regime enabling simultaneous thermal localization rejection, i.e., significantly accelerates rejection while inducing negligible additional heat loss. Furthermore, broad applicability integrating this layer with recently developed contactless evaporator report an improved efficiency. This work elucidates fundamentals transport offers low-cost strategy high-performance evaporation.
