Plasmon-enhanced solar vapor generation (SVG) has been extensively studied in the last decade as a technology for efficient water purification. 1 SVG is a natural photothermal phenomenon that induces a change in the liquid–vapor phase of water using solar energy. . Received 30th January 2025, Accepted 11th February 2025 In this work, the fabrication of the material for solar vapor generation using porous silicon treated by electrochemical etching, metal-assisted chemical etching, and electrochemical metal-assisted etching is reported. The proposed method. . Since solar energy is the ultimate energy resource and a significant amount of global energy utilization goes through heat, there have been persistent efforts for centuries to develop devices and systems for solar–thermal conversion. Due to the extinction of silicon from UV to near-infrared region, Mie resonances in silicon nanoparticles dramatically enhance the. .
