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 […]

2D Perovskites May Make Better LEDs and Solar Cells
April 15, 2021 | 1 Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Surrey engineers’ innovative analysis of two-dimensional (2D) materials could boost the development of next-generation solar cells and LEDs. Three-dimensional perovskites have proved themselves remarkably successful materials for LED devices and solar panels in the past decade. One key issue with these materials, however, is their stability, with device performance decreasing quicker than […]
