A team of scientists at Oxford University has made a significant breakthrough in solar technology with the development of an ultra-thin, light-absorbing material made from perovskite. This new technology could transform everyday objects into power-generating surfaces, offering a sustainable solution to the growing demand for renewable energy.
Perovskite coatings are far more efficient at absorbing solar energy compared to traditional silicon-based panels. These coatings are over a micron thick, making them 150 times thinner than a silicon wafer. Their thinness and flexibility allow them to be applied to a wide range of surfaces, from rooftops to car exteriors and even mobile phones. The team at Oxford has managed to increase power conversion efficiency from 6% to over 27% in just five years, bringing the technology close to the limits of what single-layer photovoltaics can achieve.
Global solar installations surged by 80% in 2023, continuing solar energy’s reign as the fastest-growing electricity source for the 19th consecutive year. However, traditional solar farms face challenges due to their large land requirements, often conflicting with agricultural use. Oxford University’s development of perovskite technology presents a promising solution, enabling solar power generation on various surfaces and potentially reducing the need for expansive farms. While challenges remain, particularly in the stability of perovskite materials, ongoing research is focused on improving their durability. Oxford PV, a university spinout, has already begun large-scale manufacturing of perovskite solar panels, positioning this technology at the forefront of the industry.
