Latest Carrier generation and recombination Stories
A perspective article published last month by University of California, Riverside chemists in the Journal of Physical Chemistry Letters was selected as an Editors Choice—an honor only a handful of research papers receive.
At low power, commonly used LEDs are very efficient. However, when these same LEDs receive enough power to light a room, they lose a significant amount of efficiency, a term referred to as the “green gap”...
JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet.
Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called “efficiency droop” that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to greater electrical currents.
Researchers have identified what causes light emitting diodes (LEDs) to be less efficient at high drive currents, opening up the door for the energy efficient lighting alternative to be better implemented.
U.S. Naval Research Laboratory scientists in the Electronics Technology and Science Division, in collaboration with the Imperial College London and MicroLink Devices, Inc., Niles, Ill., have proposed a novel triple-junction solar cell with the potential to break the 50 percent conversion efficiency barrier, which is the current goal in multi-junction photovoltaic development.
Hydrogen production by solar water splitting in photoelectrochemical cells (PEC) has long been considered the holy grail of sustainable energy research.
Plastic electronics hold the promise of cheap, mass-produced devices.
Researchers at the University of California, Santa Barbara, say they've figured out the cause of a problem that's made light-emitting diodes (LEDs) impractical for general lighting purposes.
MEDFORD and SOMERVILLE, Mass., April 8, 2011 /PRNewswire-USNewswire/ -- Assistant Professor of Electrical and Computer Engineering Tom Vandervelde has been awarded an early-career award from the National Science Foundation for promising research on the conversion of heat to electricity. Vandervelde, the John A.
