Superhydrophobic surface solar container
Inspired by the self-cleaning properties of the lotus leaf, this review proposes the use of superhydrophobic surfaces as an effective solution for soiling mitigation in solar cell applications.. The multifaceted applications of superhydrophobic surfaces arising out of their unique surface architecture have gained significant attention in the solar photovoltaic industry as it addresses the challenges in light conversion efficiency at an industrial scale due to the soiling of surfaces.. In this study, a super-hydrophobic copper foam with hierarchical micro-nanostructures exhibited temperatures greater than 66 °C under solar illumination of 1 kW·m −2. Significantly, the modified copper foam acting as a solar interface evaporator had a water harvesting efficiency of 1.76 kg·m −2 ·h.
