A collaboration between University of Toronto Engineering, Northwestern University and the University of Toledo has resulted in an all-perovskite tandem solar cell with extremely high efficiency and record-setting voltage. The prototype device demonstrates the potential of this emerging photovoltaic technology to overcome key limits associated with traditional silicon solar cells, while also offering a lower […]

On Monday, Cerebras Systems unveiled its 13.5 million core Andromeda AI supercomputer for deep learning, reports Reuters. According Cerebras, Andromeda delivers over one 1 exaflop (1 quintillion operations per second) of AI computational power at 16-bit half precision. The Andromeda is itself a cluster of 16 Cerebras C-2 computers linked together. Each CS-2 contains one […]

Solar panels glint in the sun on a Tunisian lagoon, part of a long-delayed drive to harness the North African country’s vast renewable energy potential. While industry insiders complain of red tape, fossil fuel prices that soared after Russia’s February invasion of Ukraine created a powerful incentive for such investments across the Maghreb region. “Algeria, […]

The European Union’s executive arm proposed pollution standards Thursday for new combustion engine vehicles that are expected to remain on European roads well after the 27-nation bloc bans their sale in 2035. The so-called Euro 7 standards presented by the European Commission would apply to all cars, vans, trucks and buses sold in the EU, […]

Drastically reducing greenhouse gas emissions is of utmost importance to mitigate climate change and its detrimental effects. To work toward this goal, most automotive and transport companies are investing in hybrid and electric vehicles, as well as other emission-free means of transportation. In recent years, micro-mobility technologies, such as e-scooters and e-bikes, have become increasingly […]

Audi dealers are starting to collect household electronics such as old laptops and phones so they can be recycled into electric car batteries. Why it matters: With global demand for lithium-ion batteries expected to grow by more than 500% in the next decade, it’s one way to help seed creation of a domestic battery supply chain […]

Organic photovoltaics, solar energy devices based on organic semiconductors, have so far achieved very promising results in experimental settings, both in terms of efficiency and stability. However, engineers have not yet devised reliable strategies to fabricate these devices on a large-scale at a reasonable cost. Researchers at Wuhan University in China have recently identified an […]

Most space satellites are powered by photovoltaic cells that convert sunlight to electricity. Exposure to certain types of radiation present in orbit can damage the devices, degrading their performance and limiting their lifetime. In the Journal of Applied Physics, scientists from the University of Cambridge proposed a radiation-tolerant photovoltaic cell design that features an ultrathin […]

Stanford University researchers have devised a new way to make lithium-ion battery packs last longer and suffer less deterioration from fast charging. The research, published Nov. 5 in IEEE Transactions on Control Systems Technology, shows how actively managing the amount of electrical current flowing to each cell in a pack, rather than delivering charge uniformly, can […]

Argonne researchers have created an automatic technique that can fill in gaps in X-ray data. Putting together a jigsaw puzzle is a great activity for a rainy Sunday afternoon. But the somewhat more difficult process of quickly assembling 3D scientific jigsaw puzzles—atomic structures of different materials—has recently gotten a lot easier, thanks to new research […]
