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 […]

A Safer Lead Free Perovskite Found
May 12, 2020 | Leave a Comment
A Rensselaer Polytechnic Institute team of engineers, material scientists, and physicists have demonstrated how a new material – a lead-free chalcogenide perovskite – that hadn’t previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered. A widespread transition to solar energy will depend […]

New World Record Set For a Solar Cell
April 30, 2020 | Leave a Comment
DOE/National Renewable Energy Laboratory (NREL) scientists have fabricated a solar cell with an efficiency of nearly 50%. The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at […]

Highly Efficient and Stable Double Layer Solar Cell
April 29, 2020 | Leave a Comment
A Korea Advanced Institute of Science and Technology led international research team has developed a new type of solar cell that can both withstand environmental hazards and is 26.7% efficient in power conversion. Solar cells convert light into energy, but they can be inefficient and vulnerable to the environment, degrading with, ironically, too much light […]

Solar Cells For Use Under Water
April 21, 2020 | Leave a Comment
Researchers at New York University say there may be many overlooked organic and inorganic materials that could be used to harness sunlight underwater and efficiently power autonomous submersible vehicles. Their research, published in the journal Joule, develops guidelines for optimal band gap values at a range of watery depths, demonstrating that various wide-band gap semiconductors, […]
