Solar steam generation has attracted huge research awareness about consideration owing to its high efficiency in solar energy and transformative mechanical potential. Recently, solar-driven interfacial evaporation by localization of solar-thermal energy conversion in the air/liquid interface has been suggested as a positive alternative to conventional bulk heating-based evaporation, conceivably decreasing thermal losses and progressing energy transformation effectiveness. This graduation project proposes the development of a unique 3D copper porous solar-driven evaporation design which is composed of a transparent cover (transparent bubble wrap), a spectrally selective solar absorber, an evaporation structure (hybrid copper porous foam), a wicking material (air-laid paper) and a thermal insulation (polystyrene and EPE foam). Moreover, the design is simulated in COMSOL Multiphysics software and high solar-to-steam efficiency of 48.1%. The high steam generation efficiency is reached by localizing solar-thermal heating at the evaporation surface and controlling the water supply onto the porous evaporator by adjusting its surface wettability, which anticipates overheating of the evaporator and in this way minimizes conductive, convective, and warm radiative losses from the evaporator. The unique design of the steam outlet placed at the sidewall of the evaporator encourages the collection of produced steam; in addition, it maintains a strategic distance from potential blockage of solar radiation by the condensing steam. The high-efficiency solar-driven evaporator can be utilized in many technologically critical energy-related applications such as solar-thermal energy harvesting, electricity generation, mechanical energy harvesting, and solar- chemical fuel production.
