3-D nanocone solar cell boosts PV conversion efficiency by nearly 80%

Green Car Congress

We designed the three-dimensional structure to provide an intrinsic electric field distribution that promotes efficient charge transport and high efficiency in converting energy from sunlight into electricity. With this approach at the laboratory scale, Xu and colleagues were able to obtain a light-to-power conversion efficiency of 3.2%

Sandia researchers developing new family of metal-based ionic liquids for low-cost, efficient flow batteries

Green Car Congress

Liquid electrolytes are pumped from storage tanks to flow-through electrodes where chemical energy is converted to electrical energy (discharge) or vice versa (charge). Rose, Chad L. The next step for the Sandia team is to find similar materials for flow battery anodes. Pratt III, Alyssa J. Staiger, David Ingersoll and Travis M.
