Researchers have developed a new type of high-efficiency photodetector inspired by the photosynthetic complexes plants use to turn sunlight into energy. Photodetectors are used in cameras, optical communication systems and many other applications to turn photons into electrical signals.

Researchers developed a new type of high-efficiency photodetector that is similar to the photosynthetic complexes plants use to turn sunlight into energy. The new design integrates a simple organic detector into the propagation region to produce efficient polariton-to-charge conversion over distances of up to 100 microns.

“Our devices combine long-range transport of optical energy with long-range conversion to electrical current,” said research team leader Stephen Forrest from the University of Michigan. “This arrangement, analogous to what is seen in plants, has the potential to greatly enhance the power generation efficiency of solar cells, which use devices similar to photodetectors to convert sunlight into energy.”

A radically new form of lithium-oxygen batteries avoids many of the problems that have prevented the uptake of what is, in theory, the ultimate transportation battery. If the work can be scaled up, it could mark the end of gasoline-powered cars.

The cost, weight, and insufficient lifespan of batteries represents a major obstacle to electric cars replacing internal combustion engines on our roads. There are two paths to address this: One, like Aesop’s tortoise, involves slow incremental improvements in existing lithium-ion batteries, collectively bringing down the cost and extending the range of electric vehicles.

The production of nanodiamonds from PET plastic paves the way toward a new form of recycling, and even has implications for exoplanets that rain diamonds.

Microsoft’s Ranveer Chandra explains how the company has developed different technologies to bring internet connectivity to the middle of farms.

The global rush to recycled batteries is excellent news for automakers, however, there isn’t nearly enough scrap to feed them all.

The wave of new factories poses a significant risk for the recycling industry itself, Bloomberg reported on Thursday.

“Nobody is really looking at each other, and they seem to think there will be a lot of scrap and end-of-life batteries,” Hans Eric Melin, the founder of a UK-based consultancy Circular Energy Storage(CES), told Bloomberg.

Researchers have developed a machine learning algorithm that could help reduce charging times and prolong battery life in electric vehicles by predicting how different driving patterns affect battery performance, improving safety and reliability.

The researchers, from the University of Cambridge, say their algorithm could help drivers, manufacturers and businesses get the most out of the batteries that power electric vehicles by suggesting routes and driving patterns that minimize battery degradation and charging times.

The team developed a non-invasive way to probe batteries and get a holistic view of battery health. These results were then fed into a machine learning algorithm that can predict how different driving patterns will affect the future health of the battery.
