University of Cambridge researchers have devised a new material that mimics the wing structure of owls which could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics. Because wind turbines are heavily braked […]

UCLA chemists are developing photovoltaic cells that store the electrical energy. The work is a major improvement for capturing and retaining energy from sunlight, where the stored energy can last dramatically longer than current solar technology allows. The storage can last up to several weeks, instead of the microseconds found in today’s rooftop solar panels. […]

A Global Research Center for Environment and Energy based on Nanomaterials Science of Japan (GREEN) research team has successfully developed perovskite solar cells with good reproducibility and stability as well as exhibiting ideal semiconducting properties. Perovskite solar cells are a promising low-cost and highly-efficient next-generation technology for solar cells.  The study has been published in […]

Aalto University researchers have obtained the record-breaking efficiency of 22.1 percent efficiency on nanostructured black silicon solar cells. This critical almost 4 percent absolute increase to their previous record was achieved by applying a thin passivating film on the nanostructures and by integrating all metal contacts on the back side of the cell. Most folks […]

Researchers at Fraunhofer-Gesellschaft have built a new type of steel blade for wind turbines formed from a 1.0 mm steel sheet and featuring integrated, folded reinforcement. Today’s wind turbines use very large rotor blades made with fiber-reinforced plastics that are almost impossible to recycle. But steel blades recycling ability exceeds 90 percent. Plus they cost […]
