Scientists have achieved a new world record for a next-generation solar cell, which holds the promise for novel applications like building-integrated and window solar panels. The breakthrough follows two years of research from the Hong Kong Polytechnic University into organic solar cells (OSCs), which until now have been too inefficient and costly to be used widely in practical applications. The research team invented a new technique to boost the stability of OSCs, achieving a power-conversion efficiency of 19.3 per cent. “The new finding will make OSC research an exciting field, and this will likely create tremendous opportunities in applications like portable electronics and building-integrated photovoltaics,” said Li Gang, a professor of energy conversion technology at Hong Kong Polytechnic University. “This is a very encouraging result for the long-standing research on OSCs that I have conducted over the past two decades. We have already achieved better OSC efficiency and this will subsequently help accelerate the applications of solar energy.” Professor Li and his team believe an efficiency rate above 20 per cent is now achievable using their new technique. The research is detailed in a study, titled ‘19.3% Binary Organic Solar Cell and Low Non-Radiative Recombination Enabled by Non-Monotonic Intermediate State Transition’, published in the scientific journal Nature Communications. The 19.3 per cent efficiency record is still a long way off other solar cell technologies, with researchers passing the 30 per cent barrier last year with a tandem design that used the so-called “miracle material” perovskite. OSCs are more lightweight and flexible than traditional silicon-based solar panels, as they consist of thin layers of organic semiconducting materials. The materials used are more environmentally friendly and 1,000-times thinner than silicon solar cells, meaning they have the potential to be vastly cheaper. They are also semi-transparent, allowing them to be used not just within building materials, but also on windows. Dozens of startups are already working on novel applications for harvesting solar energy, such as London-based Filia, which integrates solar technology into blackout blinds. California-based Ubiquitous Energy raised more than $30 million last year to push forward its vision of turning skyscrapers into “vertical solar farms” through the development of windows capable of converting sunlight into electricity. The firm aims to begin production at some point next year following further research and development.

If you found water that was more than two billion years old, would your first instinct be to drink it? One scientist did exactly that after finding the oldest water ever discovered on the planet. A team from the University of Toronto, led by Professor Barbara Sherwood Lollar, came across an incredible find while studying a Canadian mine in 2016. Tests showed that the water source they unearthed was between 1.5 billion and 2.64 billion years old. Given that it was completely isolated, it marked the oldest ever found on Earth.

Speaking to BBC News, professor Sherwood Lollar said: “When people think about this water they assume it must be some tiny amount of water trapped within the rock. “But in fact it’s very much bubbling right up out at you. These things are flowing at rates of litres per minute – the volume of the water is much larger than anyone anticipated.” Discussing the presence of life in the water, Sherwood Lollar added: “By looking at the sulphate in the water, we were able to see a fingerprint that’s indicative of the presence of life. And we were able to indicate that the signal we are seeing in the fluids has to have been produced by microbiology - and most importantly has to have been produced over a very long time scale. “The microbes that produced this signature couldn’t have done it overnight. This has to be an indication that organisms have been present in these fluids on a geological timescale.” The professor also revealed that she tried the water for herself – but how did it taste? “If you’re a geologist who works with rocks, you’ve probably licked a lot of rocks,” Sherwood Lollar told CNN. She revealed that the water was "very salty and bitter" and "much saltier than seawater." Have your say in our news democracy.

An algorithm has spotted a nearly 600-foot, potentially hazardous asteroid near Earth. The tool is intended to find dangerous objects in Earth’s vicinity, to allow scientists to better track them and understand any threat they might pose. The new discovery is the system’s first detection of a “potentially hazardous” asteroid, a term that is used for those rocks that are near enough and possibly threatening enough to cause a danger to Earth. An asteroid gets the designation if it is within about 5 million miles of Earth’s orbit. The asteroid, known as 2022 SF289, does not pose any threat to Earth for the foreseeable future. Its closest approach brings it 140,000 miles from Earth – closer to us than the Moon, but still far enough away to be safe. But the creators of the algorithm said that it showed that the system could be used to detect others in the future – some of which may pose a threat to life on Earth. “By demonstrating the real-world effectiveness of the software that Rubin will use to look for thousands of yet-unknown potentially hazardous asteroids, the discovery of 2022 SF289 makes us all safer,” said scientist Ari Heinze, the principal developer of the algorithm, known as HelioLinc3D. Astronomers are looking forward to switching on the Vera C. Rubin Observatory, in Chile, in 2025. It will allow for a much more detailed view of the night sky. They hope that it can be used to spot more potentially hazardous asteroids, or PHAs. But the extra detail will also make more work for those poring through the data to find them, and so algorithms will be important to helping that work. HelioLinc3D is one such algorithm, and was built specifically to find asteroids within the Rubin observatory’s dataset. Though the equipment is not yet switched on, its creators looked to test whether it would successfully be able to find asteroids when it is looking through that data. The discovery of 2022 SF289 suggests that it will be. It was found in data from the ATLAS survey, based in Hawaii. ATLAS had actually seen the object three times on four separate nights, but an asteroid has to be seen four times on one night to be identified as a near-Earth object. “Any survey will have difficulty discovering objects like 2022 SF289 that are near its sensitivity limit, but HelioLinc3D shows that it is possible to recover these faint objects as long as they are visible over several nights,” said Denneau. “This in effect gives us a ‘bigger, better’ telescope.” Until now it had also been missed because it was passing in front of the busy and bright stars of the Milky Way. But scientists were able to confirm the existence of the object by looking back through data when they knew where to look. Scientists are aware of 2,350 PHAs already, but expect there are 3,000 out there waiting to be found. “This is just a small taste of what to expect with the Rubin Observatory in less than two years, when HelioLinc3D will be discovering an object like this every night,” said Rubin scientist Mario Jurić, director of the DiRAC Institute, professor of astronomy at the University of Washington and leader of the team behind HelioLinc3D. “But more broadly, it’s a preview of the coming era of data-intensive astronomy. From HelioLinc3D to AI-assisted codes, the next decade of discovery will be a story of advancement in algorithms as much as in new, large, telescopes.” Read More Reddit closes Place after obscene protests Kenya suspends eyeball-scanning crypto worldcoin Google warns Gmail users they could be about to lose their account Reddit closes Place after obscene protests Kenya suspends eyeball-scanning crypto worldcoin Google warns Gmail users they could be about to lose their account
