solar energy

Oxford University scientists may have solved one of the greatest hindrances of expanding access to solar energy. Scientists from the university’s physics department have created an ultra-thin layer of material that can be applied to the exterior of objects with sunlight access in place of bulky silicon-based solar panels.The ultra-thin and flexible film is made by stacking layers of light-absorbing layers of perovskite that are just over one micron thick. The new materials are also 150 times thinner than a traditional silicon wafer and can produce 5 percent more energy efficiency than traditional, single-layer silicon photovoltaics, according to a statement…
