Scientists have discovered how to double the efficiency of an ultra-lightweight solar cell, which they claim could be used to harvest the Sun’s energy in space at a never-before-seen scale. The next-generation solar panels, built by a team from the University of Pennsylvania, use layers that are over a thousand times thinner than a human hair, yet capable of absorbing a comparable amount of sunlight to commercially available solar cells. The extreme thinness earned them the label two-dimensional, or 2D TMDC, as they are only a few atoms thick. The ability to produce more electricity per weight compared to traditional silicon solar cells makes them highly suitable for sending into space to harvest the Sun’s energy, according to the researchers. “High specific power is actually one of the greatest goals of any space-based light harvesting or energy harvesting technology,” said Deep Jariwala from the University of Pennsylvania. “This is not just important for satellites or space stations, but also if you want real utility-scale solar power in space. The number of [silicon] solar cells you would have to ship up is so large that no space vehicles currently can take those kinds of materials up there in an economically viable way.” By modelling the innovative solar cell computationally, Professor Jariwala and his team were able to come up with a design that has double the efficiency compared to what had previously been demonstrated. A paper detailing the research, titled ‘How good can 2D excitonic solar cells be?’, was published in the scientific journal Device on Tuesday. The researchers now hope to figure out how to achieve large-scale production for the design. “I think people are slowly coming to the realisation that 2D TMDCs are excellent photovoltaic materials, though not for terrestrial applications, but for applications that are mobile, more flexible, like space-based applications,” said Professor Jariwala. “The weight of 2D TMDC solar cells is 100 times less than silicon or gallium arsenide solar cells, so suddenly these cells become a very appealing technology.” The concept of space-based solar arrays was first theorised more than 50 years ago, with scientists noting that the Sun’s energy could be converted into microwaves and beamed down to ground-based receiving stations that convert them into electricity. It has several advantages over terrestrial setups, as they would not be limited by cloud cover or the Sun’s typical cycle. Research has accelerated in recent years following several major breakthroughs and developments with solar energy harvesting and orbital rocket launches, including the emergence of private space companies like SpaceX that have significantly reduced the cost of delivering payloads into space. Last month, Japanese space agency JAXA announced that it was aiming to set up the first satellite transmitters for a commercial-scale solar farm in space by 2025. The European Space Agency is also planning to establish a development program for this untapped renewable energy resource through its Solaris programme.

The UK and Spain are close to agreeing a deal on the post-Brexit status of Gibraltar, the Spanish foreign minister has indicated. A spokesperson for the Foreign Office said Lord Cameron had underlined the UK’s desire to get “a UK-EU treaty on Gibraltar as soon as possible” during his discussion with counterpart Jose Manuel Albares. Mr Albares first revealed he had been in crunch talks with Rishi Sunak’s new foreign secretary David Cameron on resolving the long-running row over trade and immigration arrangements. He told Spanish media that he had spoken with Lord Cameron over the phone on Monday, and they had also agreed to meet in person during a Brussels summit on Tuesday. The Spanish minister suggested the outline of a deal was now in place for a “zone of shared prosperity” in the Spanish area next to the British territory to avoid a hard border on the flow of people and goods. “I would sign a deal with Britain over Gibraltar tomorrow,” Mr Albares told the television channel Telecinco – saying both sides “agree that we have to move forward as soon as possible”. A UK-EU deal on arrangements for Gibraltar’s border – primarily on trade and free movement – was not struck in time for the Brexit deal worked out by Boris Johnson’s government. Conservative ministers have been nervous about signing any bilateral deal that could be viewed as reducing British influence over the territory. The Spanish foreign ministry has said the deal would allow Spain to use the Schengen agreement – which allows for the free movement of EU citizens around the bloc – to ease controls on the movement of people. Spain, the UK and the EU have previously agreed to the principle that Gibraltar should remain part of EU agreements on free movement. Mr Albares suggested the UK was also now keen on a frictionless border when it comes to the movement of goods – something akin to the thorny arrangements for Northern Ireland His ministry said a “zone of shared prosperity” deal would see limited checks “without increasing the risks for the EU internal market” – meaning the UK would have to agree to alignment on Brussels regulations. The Spanish foreign minister told reporters in Brussels: “I think this deal … is better for everyone than the application of European legislation after British citizens democratically decided to leave the European Union.” “There’s already been political will on the part of the Spanish government for many months,” Mr Albares said on the “generous and balanced deal on the table”. He added: “What’s needed now is that political will on the part of the United Kingdom to move forward decisively, which is what I’ve seen so far. But we won’t know until the end. Nothing will be agreed until it’s all agreed.” Despite optimism that a deal is now close, there was no word from Lord Cameron’s team on the prospects of an agreement being signed within days. Britain’s decision to leave the EU was very unpopular in the British overseas territory, where thousands of people cross the border with Spain every day for work. Just over 95 per cent of the territory’s population voted to stay in the EU in the 2016 referendum. The territory’s business leaders have been keen for a deal to be struck. Brian Reyes, editor of the Gibraltar Chronicle wrote: “Seven years on [from the Brexit referendum], the Brexit levanter still hangs over our heads.” Meanwhile, Lord Cameron is expected to try to meet EU Commission vice-president Maros Sefcovic during his Brussels summit visit – his first trip to the EU capital since his fateful Brexit referendum. The foreign secretary is reportedly ready to raise the issue of post-Brexit tariffs set to be imposed on the automobile industry into force in January if he meets Mr Sefcovic this week. Mr Sunak’s government is pushing the EU Commission to agree to delay the costly new “rules of origin” set to damage the electric vehicle (EV) market due to come in at the start of 2024 as part of Mr Johnson’s trade deal. The Independent has contacted Lord Cameron’s team and the Foreign Commonwealth and Development Office (FCDO) for comment.
