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.

Crystal Palace are hoping to persuade Graham Potter to return to management this summer. While the 48-year-old had been considering a break after his mid-season departure from Chelsea, his record from before going to Stamford Bridge still puts him in high demand for a number of progressive clubs. Palace see Potter as an ideal candidate for their next step as a club and feel they can make the Englishman a convincing offer, including the chance to work with one of the best young squads in the Premier League. The south London club have made a virtue of bringing through exciting local talent and, having being an attractive option for so many young players, now want to move onto the next stage and nurture them in a more expansive style of play. While that has long been a goal for the club’s owners, the competitive nature of the bottom half has ensured evolution has constantly been stunted by the need to stay in the Premier League. Patrick Vieira had initially impressed in a spell where his pragmatic football was considered a more steady step from the approach of previous coaches like Roy Hodgson, only for the team to run into trouble and Hodgson returning. Potter is seen as ideal for that longer-term process, given he went through exactly that at Brighton, bringing the club through a move to a new football philosophy after Chris Hughton. There is a belief within Palace they can prove persuasive, although they are likely to face significant competition given the number of clubs that are interested in the 48-year-old. Potter himself is intent on a club that has the right structure to work in.

A university professor who worked on US government programmes relating to UFOs has said he believes that "aliens are 100 per cent living among us". Dr Garry Nolan of Stanford University School of Medicine spoke about “advanced forms of intelligence” during a recent conference called The Pentagon, Extraterrestrial Intelligence and Crashed UFOs. He said: "I think it's an advanced form of intelligence that using some kind of intermediaries. It's not that they walk among us wearing a skin suit. You're going to put something there that I think of as an intelligence test." Nolan went on to say: "They're showing up and saying who amongst you are intelligent enough to realize what it is you're looking at. 'Can you see what's in front of you for what it really is? Can you see the anomalous data point?"

"I'm not worried about them coming and raiding us or taking our women and children. That's not my concern. My concern is how do we use it,” he went on to say. Meanwhile, it was recently claimed that Logan Paul could be the most important figure in the UFO-hunting community. Documentary filmmaker James Fox has spoken about a piece of footage that was rumoured to have been uncovered by UFO specialist Chuck Clark around 30 years ago. The footage is thought to have been recorded by two men in the Nevada desert and has been the focus of much speculation in the community of UFO hunters. While the clip has never been widely shared and has become the stuff of urban legend, Fox has revealed that Paul could be the key to the video being shared with the public in the future.

In the face of mounting pressure from labour shortages, supply delays and skyrocketing energy prices, celebrating British produce is more important than ever. If you’re in a supermarket during the next two weeks, look out for a British Tomato Fortnight sticker. Running until 11 June, the campaign hopes to shine a light on locally grown varieties and encourage consumers to buy British. Not only is that a boon to your carbon footprint and your health, but also to your plate – juicy and packed full of flavour, British toms are an extremely versatile cooking ingredient. They go especially well in this pasta puttanesca, which takes no more than 30 minutes to get onto the table, as well as the tomato, lemon zest and sage risotto with burrata – ultimate comfort food that’s balanced by the natural sweetness of the whole toms. Lastly, in the saffron chicken, tomato, orzo and squash stew, the toms are left whole and added it right at the end for a delightful sweet note. Get stuck in. Piccolo pasta puttanesca This dish doesn’t take much longer than the 30 minutes needed to roast the Piccolo cherry tomatoes. Perfection. Serves: 4 Ingredients: 750g Piccolo cherry tomatoes Olive oil 300g spaghetti 3 garlic cloves, finely chopped 1 red chilli, finally chopped 1 tsp tomato purée 100g pitted black olives, roughly chopped 8 anchovy fillets in oil, drained, roughly chopped 2 tbsp capers, drained 1 heaped tbsp chopped fresh basil To serve: Freshly grated parmesan Fresh basil, to garnish Method: Preheat the oven to 200C/180C fan/gas 5. Tip the Piccolo cherry tomatoes onto a baking tray and drizzle with a tablespoon of olive oil. Roast for 30 minutes. Cook the spaghetti according to packet instructions. Heat a dash of olive oil in a saucepan, add the garlic and red chilli and cook for a few minutes until aromatic. Add the tomato purée and cook for another minute. Remove the roasted tomatoes from the oven, pour any excess liquid into a bowl and set aside. Add the tomatoes (along with the chopped olives, anchovies and capers) to the pan with the garlic and chilli. Sprinkle over the chopped basil. Add a splash of the excess tomato liquid if necessary. Drain the spaghetti and serve with the puttanesca sauce topped with freshly grated parmesan and extra basil. Tomato, lemon zest and sage risotto with burrata The ultimate in comfort food, this risotto really packs in the flavour, balanced by the natural sweetness of the whole Piccolos.
