The paper introduces a novel arch-bridge photothermal fabric (ABPF) designed for efficient solar desalination. The ABPF is fabricated using a shuttle-flying weaving technique, which creates efficient warp-direction water paths. This design improves water-heat distribution at the solar evaporation interface, enhancing photothermal conversion efficiency and evaporation rate. The arch-bridge structure minimizes heat loss and maximizes the water evaporation area, making the system highly efficient and suitable for all weather conditions. Under a solar illumination of 1 kW m\(^{-2}\), the ABPF achieves a temperature of over 123 °C, an evaporation rate of 2.31 kg m\(^{-2}\) h\(^{-1}\), and a solar-vapor conversion efficiency of 99.93%. The study provides a new approach to improving sustainable seawater desalination rates.The paper introduces a novel arch-bridge photothermal fabric (ABPF) designed for efficient solar desalination.
