Researchers from the University of Turku, in collaboration with Aalto University and Wageningen University, have developed a bio-based UV protection film for solar cells that not only blocks nearly all harmful ultraviolet light but also outperforms commercial plastic films. The key ingredient is a water extract made from red onion skins.

    Nah they’re just going to extract the skin of the onion, and sell it to grocery stores with a plastic covering instead

    I see you're making a joke about it actually being worse for the environment.

    But serious answer: I think they'll be sourced from companies using bulk onions as an ingredient, who can now sell the skins for a profit, thus lowering the prices of those end products while keeping the prices of onions the same.

    So glad they put an onion in that shot—I had no idea what they were talking about until I saw it.
