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.

REDWOOD CITY, Calif.--(BUSINESS WIRE)--May 15, 2023--

A huge phosphate rock deposit discovered in Norway contains enough minerals to meet the global demand for batteries and solar panels for the next 100 years, according to the mining company that controls it. Norge Mining said up to 70 billion tonnes of the non-renewable resource may have been uncovered in south-western Norway, alongside deposits of other strategic minerals like titanium and vanadium. Phosphate rock contains high concentrates of phosphorus, which is a key component for building green technologies but currently faces significant supply issues. Phosphorus was first discovered in 1669 by German scientist Hennig Brandt, who was searching for the philosopher’s stone. While it proved ineffective in turning ordinary metals into gold, it has become an essential component in lithium-iron phosphate batteries in electric cars, as well as for solar panels and computer chips. Russia previously controlled the world’s largest ultra-pure phosphate rock deposits, with the European Union warning that these “critical raw materials” have a high supply risk. The EU is currently almost entirely dependent on imports of phosphate rock from the rest of the world, according to a report from The Hague Centre for Strategic Studies, with China, Iraq and Syria also home to large deposits. The report, which was published before the discovery of the massive Norwegian deposit, warned that the EU should be “concerned about phosphate rock shortages”. An article in the scientific journal Nature last year warned of imminent supply disruptions of phosphorus, citing Russia’s invasion of Ukraine and the subsequent economic sanctions as a potential cause of market volatility. The global economy consumes an estimated 50 million tonnes of phosphorus each year, with scientists warning earlier this year that the planet could face a “phosphogeddon” if supply trends continue. “The buyers’ market is becoming increasingly crowded by limited trade – due to political instability in several source countries, as well as international sanctions imposed on others,” Norge Mining noted in a June blog post. “This is forcing importers to fear an impending crisis.” Norway’s Minister of Trade and Industry, Jan Christian Vestre, said last month that the government was considering fast-tracking a giant mine in Helleland once analysis is completed on 76 kilometres of drill cores. If approval is given, the first major mine could begin operation by 2028. The politician said Norway’s “obligation” was to develop “the world’s most sustainable mineral industry” following the discovery of the minerals. The mining plans already have the support of the European Raw Materials Alliance, according to local reports, while local consultations continue. A spokesperson for the European Commission described the discovery as “great news” for meeting the objectives of the Commission’s raw material objectives, with Norge Mining telling Euractiv that the projected 4,500-metre-deep ore body would theoretically be capable of meeting global demand for the next century.

Robots took part in a UN session examining how artificial intelligence can be beneficial for healthcare. At the "Robots that assist and care: developing socially intelligent robots for good" event as part of the 2023 AI for Good Global Summit in Geneva, speakers explored and demonstrated how robotics can be used for socially assistive functions such as recovery and wellness. The panel also examined how robot dogs for comfort and support, robot medical assistants, expressive robots for human communication, and robot dogs that keep people safe in industrial settings and public safety operations can be used. Key issues of community acceptance, policy, and ethics were also covered. The speakers list included Ben Goertzel, CEO and Founder of SingularityNET, Maja Matarić, Professor in the Computer Science Department at the University of Southern California, Will Jackson, CEO and Founder at Engineered Arts, Brendan Schulman, Vice President of Policy & Government Relations for Boston Dynamics, and Cindy L Bethel, Professor and Director of the Social, Therapeutic & Robotic Systems Lab at Mississippi State University.
