LED Research Finds A Way To Improve Operating Efficiency
March 21, 2023 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Osaka Metropolitan University scientists succeeded in directly observing how LECs change their electronic state. Light Emitting electrochemical Cells are attracting attention as one of the post-organic LEDs. LEC observation shows they change their electronic state over time during field emission. OMU scientists found the result by measuring their optical absorption via lamp light […]

Method Developed That Stabilizes Perovskite For Solar Cells
February 3, 2022 | Leave a Comment
University of Cambridge researchers have developed a method to stabilize a promising material known as perovskite for cheap solar cells, without compromising its near-perfect performance. The researchers used an organic molecule as a ‘template’ to guide perovskite films into the desired phase as they form. Their results are reported in the journal Science. Perovskite materials […]

New OLED Could Keep Devices Running Longer Per Charge
June 29, 2021 | Leave a Comment
University of Michigan researchers have developed a new electrode that could free up 20% more light from organic light-emitting diodes. It could help extend the battery life of smartphones and laptops, or make next-gen televisions and displays much more energy efficient. The approach prevents light from being trapped in the light-emitting part of an […]

Reducing The Annoying Blue Light In A New LED
May 5, 2021 | Leave a Comment
Researchers at the University of Houston have developed a prototype LED that reduces – instead of masks – the excessive blue component, while also making colors appear just as they do in natural sunlight. To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on […]
