Find dusting those tables and dressers a chore or a bore? Dread washing the windows? Imagine keeping dust and grime off objects spread out over an area of 25 to 50 football fields. That’s the problem facing companies that deploy large-scale solar power installations, and scientists today presented the development of one solution — self-dusting solar panels ― based on technology developed for space missions to Mars. In the report, they described how a self-cleaning coating on the surface of solar cells could increase the efficiency of producing electricity from sunlight and reduce maintenance costs for large-scale solar installations.
