Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high.
In an advance that makes a more flexible, inexpensive type of solar cell commercially viable, University of Michigan researchers have demonstrated organic solar cells that can achieve 15 percent efficiency.
Research group in applied electrochemistry and electrocatalysis at the University of Alicante in Spain announced that they have developed a stand-alone system for desalinating and treating water through electrodialysis. The system is directly powered by solar energy and can be applied in off-grid areas.
Using two types of “designer” quantum dots, researchers at Los Alamos National Laboratory (LANL) in New Mexico, are creating double-pane solar windows that generate electricity with greater efficiency and create shading and insulation for good measure. It’s all made possible by a new window architecture which utilizes two different layers of low-cost quantum dots tuned to absorb different parts of the solar spectrum.
Thermochromic windows capable of converting sunlight into electricity at a high efficiency have been developed by scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
