Los Alamos National Laboratory researchers have developed new quantum dot solar cells that match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements relied on by most solar cells of this type. Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured […]

Paul Scherrer Institute researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale, which means such diodes are practically made for use in large-area room lighting. Researchers have been searching for such materials for a long […]

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 […]

City College of New York graduate researchers are reporting two breakthroughs with the successful demonstration of an LED (light-emitting diode) based on half-light half-matter quasiparticles in atomically thin materials. This is also the first successful test of an electrically driven light emitter using atomically thin semiconductors embedded in a light trapping structure (optical cavity). The […]

Tokyo Institute of Technology scientists have discovered a new strategy to design incredibly efficient perovskite-based LEDs with record-setting brightness by leveraging the quantum confinement effect. Several techniques for generation of light from electricity have been developed over the years. Devices that can emit light when an electric current is applied, are referred to as electroluminescent […]
