Oxford PV, a spin-off from the University of Oxford, says it’s achieved the world record for the most efficient solar panel.
In collaboration with Germany’s Fraunhofer Institute for Solar Energy Systems, the company says its solar panel achieved 25% conversion efficiency – the percentage of solar energy shining on a panel converted into electricity. That’s a big deal compared to the more typical 16–24% in commercial solar panels.
Oxford PV’s secret sauce is perovskite-on-silicon tandem solar cells, which could theoretically hit over 43% efficiency, leaving traditional silicon solar cells with a theoretical limit of less than 30% in the dust. Its record-setting panel cranked out 421 watts over an area of 1.68 square meters. The researchers used standard mass production gear and optimized it for the tandem technology.
Finding and describing new species can be a tricky endeavor. Scientists typically look for distinctive characters that can differentiate one species from another. However, variation is a continuum that is not always easy to quantify. At one extreme, multiple species can look alike even though they are different species—these are known as cryptic species. At the other extreme, a single species can be highly variable, creating an illusion of being different species. But what happens when you encounter both extremes simultaneously?
Herpetologist Dr Chan Kin Onn (previously at the Lee Kong Chian Natural History Museum, Singapore, now with the University of Kansas Biodiversity Institute and Natural History Museum, USA) led a study describing a new species of pit viper from Myanmar that is both similar and different from its sister species. The discovery is published in the open-access journal ZooKeys.
Porsche isn’t directly targeting the Tesla Model Y with the new Macan EV, but the two vehicles have many surprising similarities.
Engineers and material scientists have been trying to develop increasingly advanced devices, to meet the growing needs of the electronics industry. These devices include electrostatic capacitors, devices that can store electrical energy in a dielectric between a pair of electrodes through the accumulation of electric charge on the dielectric surfaces.
These capacitors are crucial components of various technologies, including electric vehicles and photovoltaics (PVs). They are often fabricated using polymers as dielectric materials, synthetic substances made up of large organic molecules with good intrinsic flexibility and insulating properties.
Researchers at Tsinghua University and other institutes in China recently introduced a new strategy to fabricate polymer composites filled with subnanosheets exhibiting highly advantageous properties. Their proposed method, outlined in a Nature Energy paper, allowed them to fabricate a 100-meter-long roll of a polymer-based subnanocomposite film.
For the first time, researchers have used bacteria to “upcycle” waste polyethylene.
Move over Spider-Man: Researchers at Rensselaer Polytechnic Institute have developed a strain of bacteria that can turn plastic waste into a biodegradable spider silk with multiple uses.

Japan’s moon lander has come back to life, the space agency said Monday, enabling the craft to proceed with its mission of investigating the lunar surface despite its rocky start.
The surprise announcement was a boost to Japan’s space program, nine days after the Smart Lander for Investigating Moon (SLIM) touched down at a wonky angle that left its solar panels facing the wrong way.
“Last evening we succeeded in establishing communication with SLIM, and resumed operations!” JAXA said on social media platform X, posting a grainy image of a lunar rock known as a “toy poodle”
The future of mobility will prioritize performance, and environment-friendly solutions as BMW hydrogen engines will change the world.
We finally got our first look at the new all-electric Porsche Macan EV this week. Porsche’s electric Macan features a 100 kWh battery pack that will reportedly be supplied by China’s CATL.
Ten years after debuting the SUV, Porsche revealed the all-electric Macan Thursday. The electric Macan is Porsche’s second EV, after the Taycan and the first fully electric SUV to wear the iconic badge.
The Macan EV is also the first existing Porsche model to receive an electric upgrade. With 87,355 Macan models handed over last year, the SUV plays a critical role in Porsche’s lineup.
