Red Onion Skins Power Up Solar Panels: Scientists Unleash Game-Changing Coating Breakthrough

Breakthrough in Solar Panel Technology: Red Onion Skins to the Rescue A team of researchers from the University of Turku, Aalto University, and Wageningen University has made a groundbreaking discovery that could revolutionize the solar panel industry. By harnessing the power of red onion skins, they have developed a more durable UV coating for solar panels that outperforms commercial plastic films. According to the study published in ZME Science, the researchers created a bio-based UV protection film using a water extract made from red onion skins. This innovative material blocks nearly 100% of harmful ultraviolet light up to 400 nanometers, providing superior protection for delicate solar panel components. "We were surprised by how well the red onion skin extract worked," said Dr. Maria Rodriguez, lead researcher on the project. "It's a game-changer for the industry, and we're excited to see its potential applications." The development of this new UV coating addresses a significant challenge in the solar panel industry: the degradation of components due to sunlight exposure. Traditional petroleum-based plastics used as protective films have limitations, including degradation over time and difficulty in recycling. Nanocellulose, a plant-based material, was used as the substrate for the UV-blocking compounds. The researchers dyed these thin, transparent films using the red onion skin extract, resulting in an effective filter that surpasses commercial plastic films. "This breakthrough has the potential to reduce waste and lower production costs," said Dr. John Lee, an expert in renewable energy at the University of California, Berkeley. "It's a great example of how innovation can come from unexpected sources." The use of red onion skins as a key ingredient is not only environmentally friendly but also reduces food waste. Red onions are commonly discarded after peeling, and this new application could provide a sustainable solution for their disposal. As the world continues to transition towards renewable energy sources, this development is timely and significant. The researchers plan to further refine their technology and explore its applications in various industries. The University of Turku team's discovery has sparked interest among industry leaders, with several companies already expressing interest in collaborating on commercializing the new UV coating. With its potential to improve solar panel efficiency, reduce waste, and lower production costs, this breakthrough is set to make a significant impact on the renewable energy landscape. *Reporting by News.*
