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 […]

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 […]

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 […]

Link√∂ping University researchers have developed a perovskite light-emitting diode (LED) with both high efficiency and long operational stability. Working with colleagues in Great Britain, China and the Czech Republic developing the perovskite light-emitting diode (LED) the team’s results have been published in Nature Communications. Professor Feng Gao, and head of research at the Division of […]

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 […]
