A startup in China is set to begin production of ultra-efficient solar panels that are made from the so-called “miracle material” perovskite. The next-generation solar cells will be manufactured at half the cost of traditional silicon cells, with 50 per cent greater efficiency, according to researchers from Nanjing University who made the design breakthrough that made mass production possible. “The raw materials for making perovskite cells are cheap and abundant, making the production costs of these cells just one 20th of traditional solar cells,” Professor Tan Hairen from Nanjing University, told state media. “Moreover, they are easier to produce and can be made in a single factory. Even with other items added, the overall cost of production is only half of that of traditional silicon cells.” Professor Tan has created a startup called Renshine Solar to move forward with commercialisation of the technology, and has already signed a government deal to build a production line in Jiangsu province this summer. The factory is expected to achieve a capacity of 150 megawatts by September, according to the South China Morning Post, with the perovskite solar panels built for use on roofs, walls, or placed on electric cars to improve their range. The perovskite solar cells (PSCs) are capable of retaining over 90 per cent of their initial performance after 600 hours of continuous operation, the team noted, making them suitable for commercial use. The researchers said the next-generation solar cells could also be used in applications ranging from building-integrated panels to space-based electricity generation. “With their lower fabrication cost, low-temperature solution processability, roll-to-roll manufacturing, and wide-bandgap tunability, PSCs have the potential to become the candidate of choice for high-efficiency tandem solar cells,” they wrote in a study detailing the new design that will enter production. “Considering the rapid progress in photovoltaic performance, PSCs have been considered to be ideal candidates for integrating with other systems to realise new innovative technologies.” The study, titled ‘Next-generation applications for integrated perovskite solar cells’, was published in the scientific journal Nature. Its publication comes just one month after a South Korean firm announced that it was aiming to commercialise tandem perovskite solar cells following a $100 million investment to fund a pilot production line next year.

Earth has received the first ever ‘alien message’ after a simulation of what extraterrestrial contact could look like was sent out by scientists. The SETI Institute produced the simulation of a radio wave from a Mars orbiter and gave hint of how alien contact would be received. The exercise was conducted to prepare experts for the “profoundly transformational experience for all humankind”. The signal was successfully decoded after taking just 16 minutes to travel through space and be picked up by telescopes on Earth. Sign up to our free Indy100 weekly newsletter It all took place as part of the A Sign in Space project led by Daniela dePaulis, who said during the live-streamed event: “It was very real. This is not the first time we have received a signal from TGO [ExoMars Trace Gas Orbiter], but this one is a real message.” The signal had to be decoded, as it couldn’t be heard on Earth without being altered. Victoria Catlett is the GBO software engineer and she explained: “A radio signal is not inherently sound, but a light wave. “When we receive it with something like a car radio, that light wave gets translated into the up and down movement in the speaker - and that is what you hear.” Of course, there’s no evidence that aliens exist at this point, but it’s good to know that we’re prepared. It comes after it was revealed that aliens could be mapping out the planet via the signals mobiles are emitting. It’s all to do with the radio transmission towers which are key to millions of people communicating around the world. These towers are constantly pumping out microwave signals as we call and message one another, and they’re found across a huge area of the Earth’s surface. Have your say in our news democracy.

When Tesla revealed its Cybertruck in 2019, it didn’t go so well. The supposedly bulletproof windows were smashed when hit by a metal ball, much to the embarrassment of chief executive Elon Musk. Now, the electric car company is nearing the point when it starts shipping the product – which it says is new and improved – but people still aren’t particularly impressed. Musk has said deliveries can be expected at the end of this year, with mass production set to begin in 2024. And during the firm’s latest earnings update this week, it gave a fresh sneak peak of the highly anticipated truck driving through a desert. But eagle eyed observers have already noticed a problem: the wiper doesn't cover the whole windscreen. Sign up to our free Indy100 weekly newsletter The Tesla Cybertruck Is Officially HERE! www.youtube.com In the video, the Cybertruck’s enormous glass windscreen has been covered in muddy water, some of which is pushed away by the long, singular wiper. But the passenger’s side is still completely covered in mud. For $40,000 dollars, which is the Cybertruck’s expected cost, it’s probably safe to say you’d be disappointed. Meanwhile, the wiper also rests upright on the side of the windscreen, unlike most cars where it sits horizontally next to the bonnet. Tesla’s design chief Franz von Holzhause also shared a picture of him standing in front of a dust-covered Cybertruck at a construction site in Texas earlier this year, and the top part of the passenger side was again untouched by the wiper. Watch the Tesla Cybertruck's Windows Get Smashed www.youtube.com People took to Twitter to criticise the design. One person said: “Am I the only one who thinks that Tesla Cybertruck Windshield Wiper needs to be better? They can put two wipers, one on each side, just like it is now or at the bottom like a traditional one.” “They can even put a pushing motion on the one they have to get more coverage.” Another person added: “I can only imagine the visibility from inside this tin can is horrible.” Even Musk is aware of the issue. He told Fox News earlier this year: “The wiper is what troubles me most.” And on Twitter, he said there's “no easy solution” to the massive windshield, saying: “Deployable wiper that stows in front trunk would be ideal, but complex.” That said, at least there’s a wiper now. The famous 2019 version didn’t even have one. Keep plugging away, Tesla galaxy brains. Have your say in our news democracy.
