A change in the Energy Act of the Czech Republic has increased the limit for mandatory licenses for generating electricity from 50 kW to 100 kW. The change applies to solar installations that produce electricity for direct consumption. September 26, 2025 Patrick Jowett The threshold for obtaining a mandatory license for electricity generation in the Czech Republic has been raised from 50 kW to 100 kW, Czech energy -regulating office Energetický Regulační úřad (Erú) has confirmed. This has been the second time in recent years, the threshold has risen after the limit was increased from 10 kW to 50 kW…

Breaking shockley-quisser barrier with cryogenic silicon solar cells Researchers from Taizhou University and the University of Delaware have reported the first experimental solar cell to exceed the long-term Shockley-quisser-efficiency ceiling for devices with one junction. Their N-type monocrystalline silicon cells achieved 50-60 percent power conversion efficiency in cryogenic temperatures of 30-50 K, almost doubled the best record of the room temperature. The study destroys conventional thinking that photovoltaic performance collapses at low temperatures. Conventional cells suffer from around 150 K by the carrier direction, but the new design changes this regime into an advantage. Suppresses fonon populations, slows the cooling…

Engineers at Monash University in Australia have developed a new catalyst that, according to them, could bring zinc air batteries “closer to Real-World, Raster scale and transport use”. September 24, 2025 David Carroll By PV Magazine Australia Monash University Researchers have developed a cobalt-iron catalyst that significantly improves performance and significantly improves the lifespan of zinc air batteries, achieving remarkable stability over “thousands of cycles.” Zinc batteries have long been announced as a potential solution for large-scale energy storage and transport applications. They have a high theoretical energy density, are made of abundant and cheap materials and are considered safer…

As part of the All-ABOVE Energy Strategy of New York, Gov. Kathy Hochul a plan to speed up the use and construction of clean energy in the state of New York to stabilize energy prices. Hochul acknowledges the short -term need to meet the increasing demand for electricity and is launching a new application for renewable energy projects and the assignment from government agencies to work together to promote relaxing renewable energy projects. A solar project built on a covered landfill in the state of New York. Castillo Engineering “While the federal government takes us back on energy policy, New…

A Chinese research group claims to have achieved a power conversion efficiency of more than 50% in an N-type solar cell with one junction by inhibiting light conversion to heat at extremely low temperatures. The result was achieved at temperatures of 30-50 Kelvin, which are a few dozen degrees above absolute zero. September 26, 2025 Emiliano Bellini Researchers from the University of Delaware in the United States and Taizhou University in China claim to have achieved a record power conversion – efficiency of “50% – 60%” in a silicon solar cell by inhibiting the thermal oscillations of the grilles at…

The Slovenian energy company HSE is developing a 140 MW floating solar project, with work that is currently underway for spatial planning activities. The Zonnefabriek has so far become the largest solar project in Slovenia and the largest floating solar array in Europe so far. September 26, 2025 Patrick Jowett Image: Hold Slovenske Elektarne Slovenia’s Holding Slovenske Elektarne (HSE), a state -owned company in state ownership, is working on a 140 MW floating solar project. The Družmirje Floating Solar Power Plant (PSE Družmirje) is set at a maximum of half of the surface of Lake Družmirje, a more formed by…

Redwire to supply solar sarray wings for the first Axiom station module Redwire Corporation (NYSE: RDW) has concluded a contract from Axiom Space to offer rollout-out Solar Array (Rosa) Wings for the Payload Power Thermal Module (AXPPTM), the first module of Axiom Station, the planned commercial orbital platform of the company. “As the market leader for Space Power Solutions, Redwire is proud to be selected as a strategic supplier to deliver Rosas for the first space station module of Axiom Space,” said Mike Gold, Redwire President of Civil and International Space. “While NASA and the industry take the following steps…

The price of silver rose above $ 44 per ounce this week after winning more than 30% in six months, with silver expert Philip Newman count PV -Magazine Next year it could exceed $ 50 per ounce, which increases the pressure on PV module makers the use of silver modules. September 26, 2025 Emiliano Bellini The silver price rose to $ 44.86 per ounce this week, the highest level in a decade. In comparison with an average silver price of $ 28.27 per ounce in 2024 and $ 23.35 per ounce in 2023. “There are many factors that contribute to…

Scientists have used a CPLEX-based MIP model and tested it on part of the 10 MW Masdar City Solar Fotovoltaic plant. In their simulation, they assume the use of two robot -like cleaning agents to work on a horizon of 90 days. The total cleaning costs were estimated at $ 7,987. September 26, 2025 Lior Kahana A research team led by scientists from the University of Sharjah of the United Arab Emirates (VAE) has developed a new model to optimize the cleaning schedule of PV panels in power plants in deserts. They have demonstrated the technology using data from a…
