Progress in Multi-Junction Solar Cells
A central stage in the development of economic solutions for the industrial use of multi-junction solar cells for power generation has been reached. For the first time, an efficiency of 25.9 percent has been achieved with a... -
KAUST Team Develops Industry-Ready Perovskite-Silicon Solar Cells
Perovskite-silicon tandem solar cells hold the promise of power conversion efficiencies well above the theoretical limit of silicon alone. But their outdoor performance in a hot and sunny climate has not been fully... -
Laser-Induced Graphene Face Masks Developed by Researchers in Hong Kong
Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to “secondary transmission”. A research team from City University of Hong... -
Smart Contact Lens Mimicking the Human Iris to Combat Eye Deficiencies
Imec, a world-leading research and innovation hub in nanoelectronics and digital technologies and CMST (an imec-affiliated research group at Ghent University), together with their partners the Instituto de Investigación... -
Habernero Peppers in the Synthesis of Silver Nanoparticles
Distinctive thermal and electrical characteristics make silver nanoparticles perfect for optics and biosensing applications. One increasingly popular application for the nanoparticles is as an antibacterial coating. Silver... -
Lasers Help Visualize Face Masks vs. Face Shields in Spread of Disease
If the United States Centers for Disease Control and Prevention (CDC) guidelines aren’t enough to convince you that face shields alone shouldn’t be used to stop the spread of COVID-19, then maybe a new visualization... -
Molecule Stores Solar Energy in Chemical Bonds
The Earth receives many times more energy from the sun than we humans can use. This energy is absorbed by solar energy facilities, but one of the challenges of solar energy is to store it efficiently, such that the energy is...

Optical Tools Enable the Study of Microplastics
Plastics have only been around since the 1950s and yet they’re everywhere: scattered in our lakes, rivers, floating on the top of oceans, and dropping to the bottom. Back in the 1950s and 60s, plastics were hailed as a useful invention, used... -
Light Research Advances Medical Diagnostics & Health
Light technologies are increasingly contributing to our health and longevity. While, for example, cancer is among the leading causes of death worldwide, death rates for individual cancer types have declined in part due to advanced research on light... -
Thin Film Hides Objects from Infrared Detectors
Researchers at the Chinese Academy of Sciences have developed an aerogel film made of DuPont Kevlar fibers that makes objects invisible to infrared detectors. A successful method for hiding objects from heat-sensing cameras could be... -
Measuring and Self-Adjusting Spectral Power Distribution of LED Systems
Researchers from the Catalonia Institute for Energy Research (IREC) at the University of Barcelona and its spin-off Ledmotive Technologies in Spain have combined two computational methods to enable solid-state lighting (SSL) to measure and... -
Perovskite NIR LED with Record External Quantum Efficiency
Researchers at Linköping University (LiU) in Sweden have produced near-infrared (NIR) light-emitting diodes (LED) of perovskite with a record external quantum efficiency of 21.6%. Because perovskites have good light-emitting properties and... -
Optical Tweezers Use Fluid Flow Instead of Light
Researchers from the universities of Glasgow, Bristol and Exeter have collaborated to create an entirely new kind of optical tweezers that use fluid flow instead of light to control particles of any material and hold light-sensitive biological... -
First of its Kind Quantum Sensor to Detect Single Photons
A new, groundbreakingly effective sensor developed by researchers at the University of Waterloo in Ontario (Canada) is the first of its kind, based on semiconductor nanowires, that can detect photons. The research breakthrough promises to...
