Soon, your windows could be generating power for your home.
Researchers at Michigan State University have developed a transparent luminescent solar concentrator—a thin, plastic-like material that can be applied to windows, car windshields, and even mobile devices to generate electricity from invisible wavelengths of sunlight. This innovation, reported in Nature Energy, could complement traditional rooftop solar panels, significantly increasing the total energy captured from the sun. Scientists estimate that widespread use of transparent solar materials could meet nearly 40% of U.S. electricity demand, helping reduce reliance on fossil fuels.
Although transparent solar cells currently operate at lower efficiencies (above 5%) compared to traditional panels (15-18%), they offer a vast amount of untapped surface area for energy harvesting. With around 5 to 7 billion square meters of glass available in the U.S., this technology has the potential to transform the way we generate clean energy. Researchers believe that combining transparent solar applications with rooftop solar and improved energy storage solutions could push the nation closer to 100% renewable energy. With ongoing advancements, this breakthrough represents a promising step toward a more sustainable future.
