Artificial intelligence is helping engineers build solar panels out of a “miracle material”. Scientists have long been excited about the possibility of new perovskite tandem solar cells, which could help bring the vastly improved efficiency of perovskite to mass production. They have an efficiency of more than 33 per cent, dramatically higher than conventional silicon solar cells. Those tandem solar cells come with a host of other benefits, too. They rely on inexpensive raw materials and can be made relatively easily. Engineers have faced a problem, however, in making them cheaply and at scale. To make them efficient, manufacturers need to make a very thin, high-grade layer of perovskite. Doing that is difficult. It relies on a complex process that varies significantly, seemingly with little explanation. Trying to improve that process has often relied on a gradual process of trying out new possibilities through trial and error. Now scientists have successfully built a new system that uses artificial intelligence to try and work out how to build those layers better. Instead of picking through video recordings to work out how different layers work, researchers were able to train a computer system to spot the hidden signs of good and bad coatings. After the system was built, it was able to be used better understand how to change the production to make it more efficient, researchers said. “These are extremely exciting results,” said Ulrich W Paetzold, a researcher from the Karlsruhe Institute of Technology, who worked on the new study. “Thanks to the combined use of AI, we have a solid clue and know which parameters need to be changed in the first place to improve production. “Now we are able to conduct our experiments in a more targeted way and are no longer forced to look blindfolded for the needle in a haystack. This is a blueprint for follow-up research that also applies to many other aspects of energy research and materials science.” An article describing the breakthrough, ‘Discovering Process Dynamics for Scalable Perovskite Solar Cell Manufacturing with Explainable AI’, is published in Advanced Materials.

New findings have revealed that time ran five times slower in the early universe, after scientists published new research into quasars. A quasar is a luminous active galactic nucleus and studying them has allowed scientists to measure time. The variation in brightness of quasars from the early universe has been measured to determine time dilation back to a billion years after the Big Bang. Experts have found that there was an era in which clocks moved five times slower than they do in the present day. The findings come as a relief to many cosmologists who have been perplexed by previous results that have come from studying quasars. The discovery that the universe is expanding led to the theorisation of “time dilation” – the idea that time moved slower the smaller the universe was. Sign up to our free Indy100 weekly newsletter Professor Geraint Lewis of the University of Sydney, the lead author of a new study, said in a statement: “Looking back to a time when the universe was just over a billion years old, we see time appearing to flow five times slower.” He continued, explaining: “If you were there, in this infant universe, one second would seem like one second – but from our position, more than 12 billion years into the future, that early time appears to drag.” To measure the extent of time dilation, scientists turned to quasars, as they are able to measure their change in brightness over a period they can estimate. The most distant quasar that is visible is 13 billion back in time and can still be seen despite its far distance. Their brightness varies due to turbulence and lumpiness in their accretion disks. Lewis explained the phenomenon as being “a bit like the stock market”. He said: “Over the last couple of decades, we’ve seen there is a statistical pattern to the variation, with timescales related to how bright a quasar is and the wavelength of its light.” Have your say in our news democracy.
