Employing transparent piezoelectric films can keep solar panels operating at peak efficiency in regions where water cleaning is impractical.
The efficiency of a solar panel is heavily dependent on having a clear and clean surface. But over time, dust and dirt buildup can block light and reduce their electricity output. Regular washing can keep these panels operating at peak efficiency, but in arid regions, another cleaning method is required that doesn’t rely on water.
Manzo et al. developed a method to loosen dirt through vibrations, using polyvinylidene fluoride (PVDF) piezoelectric films.
“By applying alternating current, these films generate mechanical vibrations that effectively dislodge dust particles,” said author Maurizio Manzo. “This water-free approach offers a sustainable alternative to traditional cleaning…
