KAUST Develops Solar Panel Coating That Self-Cleans and Harvests Water from Air

Scientists at King Abdullah University of Science and Technology (KAUST) have created a coating for solar panels that sustains their efficiency in dusty surroundings and simultaneously draws water vapor from the atmosphere, presenting a viable solution for photovoltaic systems in dry climates. This coating underwent a six-month outdoor evaluation at KAUST, where treated panels exhibited only slight performance degradation, while untreated panels under identical circumstances experienced substantial drops in output.

Additionally, the surface collected airborne moisture during nighttime hours, and this water was subsequently employed for watering plants in a controlled experiment. The accumulation of dust represents a recognized obstacle for solar power installations, particularly in areas characterized by high heat and scarce precipitation. Routine panel cleaning typically demands water and frequent maintenance, both of which add to operational expenses.

The KAUST team aimed to tackle this issue by engineering a surface capable of self-cleaning through natural environmental mechanisms. The outcome is a clear, nano-engineered coating composed of a silicone material suitable for food contact. This single layer integrates three functions: it permits sunlight to pass, repels both water and dust, and becomes slightly cooler than the ambient air at night. This cooling effect prompts moisture in the air to form droplets, which subsequently flow off the surface, removing dust particles in the process.

Qiaoqiang Gan, a professor of material science and engineering at KAUST who directed the study, stated that the research targets a practical issue for solar energy systems—preserving performance in settings where dust and heat are inevitable. He remarked that leveraging natural temperature fluctuations between day and night enables passive cleaning without requiring extra water or energy.

Beyond self-cleaning, this mechanism also allows the surface to harvest moisture from the air. In field trials, coated panels yielded over double the amount of condensed water compared to uncoated surfaces under comparable conditions. While the quantity was limited, it proved adequate for small-scale irrigation in the experiment, indicating possible applications in localized farming.

The investigation also explored how this technique might be utilized in agrivoltaic setups, where solar panels and crop cultivation coexist on the same land. By maintaining cleaner panel surfaces and offering an additional water source, the coating could promote more efficient use of land and resources in areas where energy and water management are tightly interconnected.

Manufactured through a straightforward thermal process, the coating can be applied to standard glass surfaces, enhancing its scalability. The research team is currently working to evaluate its durability and performance over extended periods and across diverse environmental conditions.
