Researchers at Konya Technical University in Türkiye have created a passive anti-soiling coating for photovoltaic panels using oleic acid-modified aluminum oxide nanoparticles. The coating was applied via spray technique and tested under laboratory and real-world conditions.

Characterization showed optimal performance with a 40-second spray and 1.5% oleic acid. Field tests revealed coated panels initially produced 0.5-0.8 W more power daily than uncoated ones, but performance declined due to high temperatures and low wind. The study highlighted the coating's potential to enhance energy production in arid regions.
