Chinese scientists developed electromagnetic glass that repels dirt without water or chemicals. Detailed in a recent Advanced Science publication, the technology could greatly improve the efficiency of solar panels and building windows.
The glass uses anomalous lateral transport to control charged particle movement precisely.
The system uses ITO electrodes and a thin PET layer to prevent discharge and protect the glass.
Design Drives Dust Away Without Reducing Visibility
As reported by the Zap Aeiou portal, the design actively drives airborne particles off the glass surface without affecting visibility.
Laboratory testing showed the system could remove up to 95.34 g/m² of contaminants in just ten seconds, while preserving optical clarity, with only a 1.6% decrease in visible light transmission.
This breakthrough is particularly important for dry regions, where dust buildup can cut solar panel output by as much as 50%.
Electromagnetic Glass Restores Solar Efficiency in Dusty Conditions
Using electromagnetic technology, the glass was able to restore up to 94.3% of the energy lost to dirt, maintaining efficiency above 89% even when tested with authentic desert dust.
Beyond lowering water use for cleaning, the material could remove the need for manual upkeep in difficult locations, leading to reduced costs and less structural degradation.
Its possible uses include glass building facades and electronic devices that depend on consistently clean surfaces.
The researchers say the glass retains its optical quality, essential for residential and industrial use.
Safety is ensured by the dielectric layer, which prevents electrical risks and helps limit long-term material wear.
