More Durable UV Coating For Solar Panels Made From Red Onion Skins
Long-time Slashdot reader fahrbot-bot shared this report from ZME Science 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 ligh...
But these plastics degrade over time and are difficult to recycle... Nanocellulose can be processed into thin, transparent films that serve as the perfect substrate for UV-blocking compounds. Even predictive modeling based on early degradation trends suggested the CNF-ROE filter could extend a solar cell's lifetime to roughly 8,500 hours. The team envisions biodegradable solar cells for smart packaging, remote sensors, or wearable devices — especially in applications where recovery and recycling are not feasible.
