natural dye made from red onion skins—combined with plant-based nanocellulose—can shield solar panels from harmful UV radiation.

 

What if food waste could protect the future of clean energy?

Researchers have discovered that a natural dye made from red onion skins—combined with plant-based nanocellulose—can shield solar panels from harmful UV radiation. The bio-based film blocks nearly all UV light while still allowing the visible light needed to generate electricity to pass through.

Even after long-term light exposure, the onion-derived coating outperformed conventional plastic UV films, showing stronger durability without sacrificing efficiency. This breakthrough points toward a future where solar panels last longer, rely less on petroleum-based plastics, and use biodegradable materials instead. Sometimes, the simplest solutions grow from unexpected places.
