Scientists have made a major breakthrough with a new type of solar panel that they claim could supercharge the transition to renewable energy sources. A team from the University of Surrey discovered that a nanoscale “ink” coating could improve stability enough to make next-generation perovskite solar cells suitable for mass production. Perovskite is cheaper and lighter than conventional silicon-based cells, as well as far more efficient, however the emerging technology currently suffers from a drop in efficiency and energy output during the manufacturing process. “Performance limits of traditional solar cells are why researchers are switching to examining perovskite as the next-generation solar technology, especially as applications both terrestrial and in space are rapidly growing,” said Dr Imalka Jayawardena from the University of Surrey’s Advanced Technology Institute (ATI). “Our key development in solar panel technology shows a cost-effective approach to scaling of perovskite solar cells, a development which could help countries around the world to reach their net zero targets faster.” The breakthrough was made when the researchers identified an aluminium oxide that minimises the drop in efficiency during the conditioning of perovskite solar cells. Perovskite has been hailed as a “miracle material” for its potential to transform an array of industries, from ultra high-speed communications to renewable energy. Recent advances have seen it used to create self-healing solar panels that can recover 100 per cent of their efficiency after being damaged by radiation in space, as well as break new efficiency records when combined with silicon to form tandem cells. If the cheap-to-produce perovskite cells can be manufactured at scale while retaining their durability and reliability, then the cost of solar panels would plummet. “Solar and wind energy costs are rapidly decreasing based on technology improvements, to the level where worldwide over 80 per cent of all new additional power generation capacity is based on renewables,” said Ravi Silva, from the ATI, University of Surrey. “The levelized cost of solar electricity is now cheaper than most other power-generating sources. With the maturing of perovskite solar modules, the levelized cost of electricity will significantly decrease further, and that is why this is such an exciting area to work.” The research was detailed in a study, titled ‘Modification of Hydrophobic Self-Assembled Monolayers with Nanoparticles for Improved Wettability and Enhanced Carrier Lifetimes Over Large Areas in Perovskite Solar Cells’, published in the peer-reviewed scientific journal Solar PRL.

Ukraine's forces have pushed back Russian troops in areas of the country's south and east as Kyiv pushes on with its counteroffensive – with President Volodymyr Zelensky also claiming that his country has developed a new long-range weapon. The pronouncement by Mr Zelensky that the unnamed weapon reached a target of more than 400 miles (700 kilometres) away comes a day after a wave of drone strikes across six regions in Russian. Those strikes included an assault that caused a huge fire at a military air base in Pskov in northern Russia, damaging several giant military transport planes on the tarmac. That air base is roughly 400 miles from the Ukrainian border. Whether Mr Zelensky's remarks are part of the information war with Russia over Moscow's 18-month invasion – he did not give details on the new weapon other than the fact it was produced by Ukraine's Ministry of Strategic Industries but gave no other details – it is certainly the clearest suggestion that Kyiv was behind the attack. Ukraine has upped the number of drones attacks on Russian territory in recent weeks, but rarely officially claims them. Western allies of Kyiv are wary of such attacks, although Mr Zelensky has repeatedly said that his nation has the right to hit military targets. Russia reported overnight drone attacks in its Bryansk region on Thursday and said it had shot down a missile fired on occupied Crimea. On the ground in Ukraine, Kyiv's troops have secured some new “successes” in the south and east. Ukraine's foreign minister Dmytro Kuleba has said this week that recent gains on the southern front could enable open the door to the recapture of the annexed Crimean peninsula. He told critics of the pace of its three-month-old counteroffensive to "shut up" – the sharpest signal yet of Kyiv's frustration suggestions from some Western officials, quoted in US media reports, that Kyiv's troops are moving too slowly. "Criticising the slow pace of (the) counteroffensive equals ... spitting into the face of (the) Ukrainian soldier who sacrifices his life every day, moving forward and liberating one kilometre of Ukrainian soil after another," Mr Kuleba said. "I would recommend all critics to shut up, come to Ukraine and try to liberate one square centimetre by themselves," he said at a meeting of EU foreign ministers in Spain. After months of fighting their way through heavy minefields, Ukraine's forces have finally reached the main Russian defensive lines in the Zaporizhzhia region, where Robotyne is located, in recent days. If troops can find a way past anti-tank defences and other Russian traps, a further advance there would provide the first test of Russia's deeper defences, which Ukraine hopes will be more vulnerable and less heavily mined than the areas its troops have traversed so far. Elsewhere, the Foreign Office confirmed the death of a British man whose family said he was fighting in Ukraine. Samuel Newey, 22, was "killed in action" on Wednesday in eastern Ukraine, his brother, Daniel Newey, said in a social media post. Meanwhile, BAE Systems said it had established a local entity in Ukraine and signed deals with the Ukrainian government to help ramp up the supply of weapons, equipment and training to the country. Britain is a key defence supplier for Ukraine and BAE, as the UK's biggest defence contractor, has manufactured a significant amount of the hardware provided to Kyiv. The new agreements will facilitate BAE's future support by helping it better understand Ukraine's capability requirements, and they will also allow the company to work directly with Ukrainian partners with a plan to produce 105mm Light Guns there.
