In a new weekly update for pv magazineOPIS, a Dow Jones company, provides a brief overview of the major price trends in the global PV industry. December 5, 2025 OPIS The Global Polysilicon Marker (GPM), the OPIS benchmark for polysilicon produced outside China, was valued at $18,319/kg, or $0.038/W, this week, remaining unchanged week-on-week, according to the OPIS Global Solar Markets Report published on December 2. Trading activity in the global polysilicon market remained limited, without significant fundamental shifts. Industry insiders describe current transactions as “intermittent.” Downstream manufacturers are reportedly discouraged by the high premiums on global polysilicon, while at…

When I think about the future of our industry, I am optimistic not only about the role we play in decarbonizing Europe, but also about our potential to redefine leadership, justice and opportunity in a rapidly evolving world. Solar energy and batteries are expanding at an extraordinary pace and will very soon become Europe’s main source of energy. The industry’s mission is to provide clean, affordable energy for all, but it must also be aligned with social objectives. By 2030, Europe’s solar workforce is expected to reach almost one million people, up from around 860,000 today. Unlike traditional industries that…

German start-up SPH has installed its ThermBooster heat pump at Philip Morris International’s Italian factory, which produces high-temperature steam of 139 C. The system increases energy efficiency, reduces gas consumption by up to 50% and recovers 20-30% of the water from the exhaust. December 4, 2025 Lior Kahana German heat pump start-up SPH has supplied one of its steam-producing heat pumps to tobacco giant Philip Morris International. The ThermBooster unit was installed at Philip Morris’ factory in Bologna, Italy, by Dutch system integrator JOA Air Solutions. The system upgrades the residual heat from 36 C through a two-stage compression and…

The U.S. Department of Energy has renamed it National Renewable Energy Laboratory (NREL) de National Laboratory of the Rockies. The new name is effective immediately and will be reflected in all public communications and official correspondence. “The energy crisis we face today is different from the crisis that gave rise to NREL,” said Audrey Robertson, Assistant Secretary of Energy (EERE). “We are no longer in the business of picking and choosing energy sources. Our top priority is investing in the scientific capabilities that will restore American manufacturing, reduce costs and help this country meet its rising energy demands. The National…

The two-terminal perovskite-silicon tandem solar cell was fabricated via a chemical polishing method that selectively removes residual lead(II) iodide from the perovskite film in the top cell. This focused interface engineering improved uniformity and stability, enabling a certified efficiency of 31.71% and improved long-term performance. December 5, 2025 Emiliano Bellini A group of researchers led by China’s Northwestern Polytechnical University has developed a two-terminal (2T) perovskite-silicon tandem solar cell via an interface engineering strategy that removes residual lead(II) iodide (PbI2) from the wide bandgap perovskite cell without damaging its lattice. PbI2 formation in wide band gap perovskite solar cells arises…

An international team of researchers has completed a preliminary techno-economic study on the global potential for offshore floating PV (OFPV). The results provide benchmarking of project costs, country-specific economic assumptions and a global assessment of the levelized cost of electricity (LCOE) for offshore solar. December 5, 2025 Valerie Thompson An international team led by researchers from the Australian environmental and energy focused unit of RINA Consulting, part of Italy-based RINA, has analyzed offshore FPV (OFPV) resources worldwide based on technical feasibility, energy production and costs in an effort to provide estimates on suitable locations, costs and energy generation potential. The…

The US-based manufacturer has completed certification of its latest glue-free, fluorine-free backsheet. December 5, 2025 Valerie Thompson US-based solar materials manufacturer Endurans Solar has announced its new HP D15T transparent backsheet for utility-scale bifacial projects. “Our unique U.S.-made backsheets provide domestic module manufacturers with improved supply chain stability and give developers the ability to increase their domestic content ratio, enabling a critical strategic advantage for projects targeting Inflation Reduction Act (IRA) tax credits and U.S. government procurement requirements,” said Nate Coleman, CEO of Endurans Solar, in a statement. The adhesive-free, fluorine-free backing, called HP D15T, has completed IEC 62788-2-1:2023 certification…

Global energy storage shipments rose 84.7% in the first three quarters of 2025, with Tesla and Chinese manufacturers leading the way, InfoLink says. December 5, 2025 Vincent Shaw By ESS news InfoLink’s latest rankings, drawn from the energy storage supply chain database, show that global ESS deliveries reached 286.35 GWh in the first and third quarters of 2025, with volumes exceeding 100 GWh in a single quarter for the first time in the third quarter. Market concentration remained high, with the top ten suppliers (CR10) accounting for roughly 60% of shipments, indicating that a clear leading cohort has emerged, even…

Swedish independent energy producer Alight has completed a 215 MW solar project in Lolland, southern Denmark. Construction of the Lidsø solar park started in the summer of 2024. December 5, 2025 Emiliano Bellini Alight has switched on a 215 MW solar farm – billed as Denmark’s second largest to date – in the southern municipality of Lolland. Construction of the Lidsø solar park started in the summer of 2024. The plant, developed and built by Denmark-based European Energy, will supply electricity The Danish State Railways (DSB) has entered into a long-term power purchase agreement (PPA), Alight said in a statement.…

The Japanese conglomerate has deployed its Panasonic HX hydrogen solution at its Munich factory. The system uses an AI-based power management system that reportedly eliminates the need for battery storage. December 5, 2025 Emiliano Bellini Panasonic has announced that it has started testing its Panasonic HX hydrogen energy solution at its office in Munich, Germany. The Panasonic HX platform typically consists of a renewable energy generator, Panasonic PH3 fuel cells and battery storage. However, for the German project, batteries were deemed redundant thanks to an AI-based energy management system (EMS) that performs real-time fuel cell control in response to fluctuations…
