Nanocellulose treated with red onion dye provides effective UV protection for solar cells

Researchers investigated how to use bio-based materials to produce effective UV protection films for solar cells. The study was the first to compare how the properties of different bio-based UV filters change over time.

Nanocellulose treated with red onion dye provides effective UV protection for solar cells - Tech and Science Post

Researchers at the University of Turku, Finland, investigated how to use bio-based materials to produce effective UV protection films for solar cells. The study, published in ACS Applied Optical Materials, was the first to compare how the properties of different bio-based UV filters change over time. Solar cells are prone to UV-induced degradation and are most often protected against it by petroleum-based films, such as those made of polyvinyl f…

Onion-skin dye may find use in greener UV-protected solar cells

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.Continue ReadingCategory: Environment, ScienceTags: University of Turku, Aalto University, Wageningen University, Solar Cell, Ultraviolet, Biodegradable

Nanocellulose infused with red onion extract shields solar cells from UV degradation

Berlin, Germany (SPX) Mar 20, 2025 Researchers at the University of Turku in Finland have developed a bio-based film that provides high-performance UV protection for solar cells, utilizing nanocellulose treated with red onion skin extract. This marks the first comparative study of how various bio-derived UV filters perform over time. Solar cells, susceptible to damage from ultraviolet radiation, are typically shielded by pe
