Outdoor performance and durability testing of antireflecting and self-cleaning glass for photovoltaic applications

Nanostructured glasses have been exposed outdoors for 12 weeks to test their durability, antireflective and self-cleaning performance. It was seen that nanostructured glass sample with 200-nm high nanostructures provided superior antireflective and self-cleaning effect as compared to planar glass over the testing period. This particular nanostructured glass sample also provided the best performance when tested as the packaging cover of a solar module, with reduction in efficiency by only 0.3% over a testing period of 5 weeks.
