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.

SAN FRANCISCO--(BUSINESS WIRE)--Jul 25, 2023--

The football association of Ukraine has written to Uefa’s member nations urging them to boycott matches against junior Russian teams. Uefa announced earlier this week that it would be reinstating Russia at under-17 level. The decision comes after a ban on all Russian sides by European football’s governing body after the invasion of Ukraine by Moscow in February 2022. England’s Football Association (the FA) had been among the national bodies that had said that they would not allow their sides to play Russia despite Uefa’s decision. And the Ukrainian footballing body has now urged all members to do the same. “We are convinced any step towards reintegration of Russian representatives is a hazardous and terrifying trend, which means nothing but support to the Russian terrorist state and all their crimes committed in Ukraine,” said the letter, according to the BBC. The next Under-17 male European Championship finals are due to be played in Cyprus next year, while the women’s U17 Euros are set to be hosted by Sweden in May. Sweden’s FA has also said that it will not allow age-group sides to face Russia and will not host the country, even if there is now a path to qualification. Uefa’s executive commitee is expected to meet on 10 October to confirm their position. Aleksander Ceferin, the president of Uefa, this week said that the move to relax the blanket ban came out of a desire to not punish children for the action’s of the Russian government amid the ongoing conflict. “Uefa’s continuing suspension against Russian adult teams reflects its commitment to take a stand against violence and aggression. Uefa is determined that this position will continue until the war is over and peace restored,” said the organisation’s president Aleksander Ceferin. “But by banning children from our competitions, we not only fail to recognise and uphold a fundamental right for their holistic development but we directly discriminate against them. “By providing opportunities to play and compete with their peers from all over Europe, we are investing in what we hope will be a brighter and more capable future generation and a better tomorrow.” Read More Russia to return to Uefa competitions as ban lifted on Under-17s teams EU lawmakers ask UEFA to ban Belarus from Euro 2024 Russia Olympic chief fuming over ‘unacceptable’ Asian Games exclusion
