In recent years, perovskite solar cells have seen a performance increase exceeding 20% efficiency in laboratory-scale devices. 1 For example, adding a perovskite layer to a silicon photovoltaic cell to create a tandem cell widens the absorption range of photovoltaic devices. So far, none of these technologies have gotten to the point where they're close to competitive with traditional tech like silicon. We talked to two people who focus on solar energy at the Department of Energy: Landis Kannberg of the A new optical device that separates and concentrates sunlight has been developed by researchers at the Masdar Institute of Science and Technology. In conventional solar cells, only some of the sun’s wavelengths are converted into electricity Because the charger is actually a 5.5-watt solar panel and battery, it can hold power, meaning it doesn't need to be in the sunlight to charge devices. When it is it sends power to the device's battery. When nothing's plugged in, the power gets stored for Scientists at the Department of Energy’s Oak Ridge National Laboratory have found a way of making solar panels and semiconductor devices less costly and more efficient thanks to a simple solvent. The ultra-thin films used in solar panels and Credit: Oak Ridge National Laboratory Advances in ultrathin films have made solar panels and semiconductor devices more efficient and less costly, and researchers at the Department of Energy's Oak Ridge National Laboratory say they've found a way to .

New Delhi, Oct 17 (IANS) Emphasising the need for adopting alternate sources of energy to combat climate change, union Science and Technology Minister Harsh Vardhan on Saturday directed his ministry officials to ensure development of cost effective and Itron’s new Riva-equipped Solar Gateway devices are meant to fix these problems. “This is the evolution of Itron’s solar solutions,” Roberto Aiello, head of Itron’s New Business Innovation team, said during a demo of the yet-to-be-released product. Bell envisions a scenario where such a solar-fuel device could be coupled with large solar energy installations. Surplus solar energy that is not immediately used as electricity could produce fuel that would be stored for a rainy day. This type of solar Alta Devices will introduce the new "Solar for UAV Index" which is designed to assess solar technologies for fixed wing UAV (unmanned aerial vehicle) applications. This new index accounts for many of the issues that a designer must consider. Included in .
