The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research from Oxford Brookes University has found that the vertical turbine design is far more efficient than traditional turbines in large scale wind farms, and when set in pairs the […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Surrey engineers’ innovative analysis of two-dimensional (2D) materials could boost the development of next-generation solar cells and LEDs. Three-dimensional perovskites have proved themselves remarkably successful materials for LED devices and solar panels in the past decade. One key issue with these materials, however, is their stability, with device performance decreasing quicker than […]

Consumers and utility companies have worried for years that solar panels drive up electricity costs for the people who don’t have panels. But Michigan Technological University renewable energy researchers show the opposite is actually true – grid-tied solar photovoltaic (PV) owners are actually subsidizing their non-PV neighbors. Beyond the environmental benefits and lower electric bills, […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) scientists have set the current world record of 29.15% efficiency for a tandem solar cell made of perovskite and silicon. The tandem cell provided stable performance for 300 hours – even without encapsulation. To accomplish this, the group investigated physical processes at the interfaces to improve the […]

SLAC National Accelerator Laboratory scientists have discovered how to stabilize perovskite solar cells with pressure from a diamond anvil cell. The required pressure is well within the reach of industrial manufacturing requirements. The promising lead halide perovskite solar cell is great at converting sunlight to electricity and this development could solve the cells breaking down […]
