The paper presents a scalable, high-performance, and salt-resistant solar-driven desalination technology using photo-electro-thermal textiles. The authors develop a composite braiding electrothermal fabric (CBEF) with a core (commercial electric wire) and shell (polypyrrole-decorated Tencel) structure, which integrates electrothermal and photothermal conversion. The CBEF is optimized through the regulation of wrapping eccentricity and pitch to achieve high surface temperatures and stable evaporation rates. Under 3 V DC input and 1 kW m\(^{-2}\) radiation, the CBEF demonstrates an evaporation rate of 5.57 kg m\(^{-2}\) h\(^{-1}\) for pure water and 4.89 kg m\(^{-2}\) h\(^{-1}\) for 3.5 wt.% brine. Outdoor experiments show that the CBEF can collect over 46 kg m\(^{-2}\) d\(^{-1}\) of water over a full day, with an average desalination energy consumption of approximately 1.29 kW h m\(^{-3}\). The CBEF remains robust and salt-free after consistent operation in high-concentration brine, making it a promising solution for commercial and scalable solar-driven desalination.The paper presents a scalable, high-performance, and salt-resistant solar-driven desalination technology using photo-electro-thermal textiles.
