New World Record Set For a Solar Cell
April 30, 2020 | Leave a Comment
DOE/National Renewable Energy Laboratory (NREL) scientists have fabricated a solar cell with an efficiency of nearly 50%. The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at […]

Highly Efficient and Stable Double Layer Solar Cell
April 29, 2020 | 1 Comment
A Korea Advanced Institute of Science and Technology led international research team has developed a new type of solar cell that can both withstand environmental hazards and is 26.7% efficient in power conversion. Solar cells convert light into energy, but they can be inefficient and vulnerable to the environment, degrading with, ironically, too much light […]

Cool Electronics and Recover the Heat
April 28, 2020 | Leave a Comment
Researchers reporting in American Chemical Society’s (ACS) Nano Letters have developed a hydrogel that can both cool down electronics, such as cell phone batteries, and convert their waste heat into electricity. Sometimes using electronic devices for too long with too much power can cause them to overheat, which might slow them down, damage their components […]

New Electronics to Use Quantum Spin State of Electrons
April 22, 2020 | Leave a Comment
University of Leeds scientists have made a breakthrough in the development of a new generation of electronics that will require less power and generate less heat. It involves exploiting the complex quantum properties of electrons – in this case, the spin state of electrons. In a world first, the researchers – led by a team […]
