Researchers have developed a bio-based ultraviolet (UV) protection film that has the potential to replace conventional petroleum-derived materials in solar cells. Their study represents the first comprehensive analysis comparing the long-term efficacy of different bio-based UV filters.

Researchers from the University of Turku, Finland, have found a new way to protect solar cells from harmful UV radiation using natural materials. Their study, published in ACS Applied Optical Materials,

Solar cells are subjected to a lot of harmful ultraviolet light, as they're typically placed for maximum sunlight exposure. A new eco-friendly coating could help protect them from those UV rays, and its active ingredient is extracted from onion skin.
