Scientists break out infrared tech to solve issue holding back next-gen solar panels: 'This makes the technology promising not just in the lab'
In a major leap for clean energy, scientists have figured out how to make solar panels that are lighter, more efficient, and — for the first time — durable enough for everyday use. A research team led by the Swiss Federal Institute of Technology in Lausanne, Switzerland, has developed a new method for making perovskite solar cells more stable in real-world conditions. The results, published in Joule, are exciting for solar fans everywhere.
Perovskites have long been considered the future of solar. Unlike traditional silicon panels, they are ultra-light and low-cost and can be printed onto flexible surfaces. Think solar-powered windows, walls, or even wearable electronics. But until now, they've had one big flaw: They don't hold up well to sunlight and heat over time.
According to this study in collaboration with the Polytechnic University of Milan, that might be about to change. The researchers found that by adding a molecule called TEMPO to the perovskite layer and hitting it with a quick infrared pulse — just half a second long — they could repair tiny defects in the material. This new process gives the panel efficiency of over 20% and maintains it for months under typical working conditions.
"The proposed method is fast, solvent-free, and compatible with roll-to-roll processing, similar to that used in the printing industry. This makes the technology promising not just in the lab, but also for future industrial-scale production," explained Rafael Ferragut, researcher, teacher, and co-author of the study.
For consumers, this could mean a new generation of solar products that are cheaper, lighter, and more versatile. These panels could help homeowners and cities break free from high, unpredictable utility bills by giving them more control over when and where they generate power. It also means reducing planet-warming pollution that harms public health and the environment. While the tech may still be in development, this breakthrough brings us one step closer to a future where clean energy is embedded into everyday life — literally.
Installing solar panels is the ultimate home energy hack because it can bring your cost of energy down to or close to $0. EnergySage provides a free service that makes it easy to compare quotes from vetted local installers and save up to $10,000 on solar installations.
For those not ready to buy, leasing is a great option. Palmetto's LightReach program locks in low energy rates for homeowners who want to switch to solar without paying high upfront costs. Community solar programs are another alternative for people who can't install panels but would like to benefit from lower energy costs and a more stable power supply.

Ablation Still Best Option When Patient Has AF and Obesity
Demonstrating that the best solution is not always a multistage approach, a new trial shows catheter ablation is superior to a combination of antiarrhythmic drugs and lifestyle changes — weight loss, more exercise, and alcohol reduction — when treating atrial fibrillation (AF) in patients who also have obesity. The PRAGUE-25 trial, led by Pavel Osmancik, MD, PhD, with the Cardiocenter at Charles University in Prague, found catheter ablation was roughly twice as effective in an intention-to-treat analysis at controlling AF at the 1-year mark compared with a combination of antiarrhythmic drugs and lifestyle modification (73% vs 34.6%). A 'referral to [catheter ablation] in this population should not be delayed until the patient loses weight,' according to the researchers, who published their findings online on June 30 in the Journal of the American College of Cardiology simultaneously with a presentation at theNew York Valves 2025 Conference. Obesity: A Strong Predictor of AF AF, the most common sustained heart arrhythmia, affects about 60 million people worldwide. Obesity is one of its strongest predictors. An increase in BMI of 5 has been linked with a 19%-29% higher incidence of the rhythm disorder. The PRAGUE trial was a randomized, noninferiority trial conducted in five centers in the Czech Republic. Patients that were included had symptomatic AF (paroxysmal, persistent, or long-standing persistent) and a BMI of 30 to 40. Patients were randomly assigned 1:1 either to receive catheter ablation (n = 100) or a combination of medication and lifestyle changes (n = 103) from May 2021 to November 2023. Baseline characteristics were balanced, according to the researchers. After randomization, all patients had a baseline cardiopulmonary exercise test, echocardiography, quality of life analysis, blood biochemistry testing, and a baseline 7-day electrocardiographic Holter recording. Patients in the catheter ablation group underwent ablation within 6 weeks of randomization. Lifestyle modification was started within 4 weeks after randomization and was managed by teams of dietary specialists and physiotherapists, rather than cardiologists. Patients in the combination therapy group lost significantly more weight at 12 months (about 6 kg, P < .001 compared to 0.35 kg in the other group), and that weight loss was maintained through the 24-month follow-up. The weight loss goal in this trial was 10%, an ambitious target in the period, especially given the physical limitations associated with AF. Ramesh Hariharan, MD, cardiac electrophysiologist at UTHealth Houston and Memorial Hermann Health, Houston, who was not part of the study, said much of this research was conducted before the widespread use of GLP-1 receptor agonists, and those medications may help current patients achieve greater weight loss faster. But even with greater weight loss, Hariharan said, the new findings reinforce the idea that no option alone is enough. Lifestyle changes and medicines need to accompany ablation, not replace it, he said, 'otherwise we're going to end up doing [ablations] more frequently.' What's more, technology has improved in the last year with nonthermal pulsed field ablation, which offers 'far fewer collateral damage complications' and results in a 45-minute procedure 'compared to a 2- to 4-hour procedure before. It has made ablation a lot easier.' Gregory M. Marcus, MD, MAS, associate chief of cardiology for research at UCSF Health, San Francisco, said the evidence 'is already definitive that catheter ablation is superior to antiarrhythmic drugs, and there is evidence that successful lifestyle change can reduce the burden of atrial fibrillation.' But this trial is the first to show a head-to-head comparison of ablation with a combination of antiarrhythmic drugs and lifestyle changes. Marcus said he is not convinced the findings exclude the possibility some in this patient population may still be able to treat their AF without ablation. 'For an obese, very sedentary person who drinks too much alcohol, those are, at least theoretically, the prime candidates for lifestyle modification as a way to effectively treat their Afib,' he said. One important lesson, Marcus said, is that this adds to the growing evidence that when considering the population at large with AF, 'on average, catheter ablation is pretty definitively the most effective way to reduce the chance of atrial fibrillation recurrence.' But some of the most interesting results were in the group who underwent lifestyle modification, he said. In addition to weight loss and improved exercise capacity, they experienced a statistically significant decrease in hemoglobin A1c concentrations of 1.4 mmol/L compared with an increase of 2.5 mmol/L in patients who received catheter ablation. 'Those are things that will prolong life and will also improve quality of life,' he said. 'Whether we're going to do an ablation or not,' Marcus added, 'we should always counsel our atrial fibrillation patients about healthy lifestyle management. There are other things to life besides atrial fibrillation.' The study authors and Hariharan reported no relevant financial disclosures. Marcus is a consultant and was a co-founder of the startup InCarda Therapeutics, which is investigating a novel therapy for the treatment of acute AF.

Landmark EU tech rules holding back innovation, Google says
By Foo Yun Chee BRUSSELS (Reuters) -Alphabet's Google will on Tuesday warn EU antitrust regulators and its critics that landmark European Union rules aimed at reining in Big Tech are hampering innovation to the detriment of European users and businesses. The U.S. tech giant will also urge regulators to give more detailed guidance to help it comply with the rules, and ask its critics to provide evidence of costs and benefits to prove their case. Google is under pressure to address charges under the EU's Digital Markets Act that it favours its own services such as Google Shopping, Google Hotels and Google Flights over rivals. The charges may result in fines of as much as 10% of its global annual revenue. Earlier this month, Google proposed more changes to its search results to better showcase rival products, but critics say these still do not ensure a level playing field. "We remain genuinely concerned about real world consequences of the DMA, which are leading to worse online products and experiences for Europeans," Google's lawyer Clare Kelly will tell a workshop organised by the European Commission to give Google critics the opportunity to seek clarifications. She will say changes implemented by Google to date after discussions with the Commission and its critics have resulted in European users paying more for travel tickets as they cannot directly access airline sites, according to a copy of her speech seen by Reuters. Kelly will also say European airlines, hotels and restaurants have reported up to a 30% loss in direct booking traffic, while users have complained about clunky workarounds. Google's other lawyer, Oliver Bethell, will ask regulators to spell out in detail what the company needs to do, and critics to come up with hard evidence. "If we can understand precisely what compliance looks like, not just in theory, but taking account of on the ground experience, we can launch compliant services quickly and confidently across the EEA," he will say. The EEA is the 27 EU countries, Iceland, Liechtenstein and Norway. "We need help identifying the areas where we should focus. That means bringing real evidence of costs and benefits that we can take account of with the Commission," Bethell said. The day-long workshop starts at 0700 GMT.

US Startup Bets on Battery Boom With Northvolt Polish Purchase
California startup Lyten is buying a Polish energy-storage factory from Northvolt AB in a bid to become a global leader with its sulfur-based batteries. Lyten, which last year bought another Northvolt's plant in the US, is planning to use the Polish unit as a hub for its international operations. The Swedish manufacturer filed for bankruptcy earlier this year as it expanded too fast and run out of cash.
