A Swedish government agency is investing 130 million SEK ($13.8 million) in Exeger’s next generation indoor solar cell technology. The company’s Powerfoyle solar cells are an evolution of dye-sensitive solar cells and are said to offer a thousand times better conductivity. December 3, 2025 Patrick Jowett The Swedish Energy Agency has awarded SEK 130 million ($13.8 million) to Swedish deep-tech company Exeger to support the development and industrialization of its next-generation indoor solar cell technology. Exeger’s solar cells, known as Powerfoyle, are capable of converting both indoor and outdoor light into electricity. Billed as the world’s only fully customizable solar…

Solar and storage industry leaders from China and Europe gathered in Germany this week to promote cross-border partnerships, launch a bilateral storage cooperation platform and coordinate strategies for scaling PV and battery deployment amid rising demand, grid pressure and increasing market competition. December 3, 2025 Brian Public China and European solar and storage leaders met this week in Dusseldorf, Germany, to call for deeper cross-border cooperation as both regions face record PV volumes, rising storage demand and complex market dynamics. Speakers at the China-EU Solar & Energy Storage Industries Dialogue 2025 highlighted the growing interdependence between China’s production scale and…

EcoFlow, Tibber and Fenecon have introduced new software and hardware updates to improve battery management, interoperability and network arbitration across Europe. December 3, 2025 Tristan Rayner By ESS news The evolution of residential battery storage has seen significant developments in design, safety, functionality and cost, both in terms of physical batteries and hybrid inverters, but also in software features. The battle for home energy management systems, or HEMS, is just as fierce on the hardware battery and mobile technology side, and includes both manufacturers and third-party software that potentially deliver better everyday experiences – think using Apple’s CarPlay to control…

Chinese module manufacturer Longi says its Hi-MO 9 series with HPBC 2.0 cells achieved watt-for-watt power gains of 1.21% to 3.92% in real-world testing in multiple countries and climates, reducing levelized electricity costs (LCOE) compared to regular tunnel oxide passivated contact (TOPCon) modules. December 3, 2025 Patrick Jowett Chinese module manufacturer Longi has published field data from a series of tests with its Hi-MO 9 module series. The flagship product of Longi’s back-contact (BC) series, revealed earlier this year, the Hi-MO 9 module was built on the company’s HPBC 2.0 high-efficiency cell technology. The test scenarios include environments including temperate…

Energy Toolbase and Napa-based EPC BPi successfully deployed three energy storage systems (ESS) at the Korbel Winery in Sonoma County, California. The installation is part of the winery’s broader commitment to promote sustainability and integrate renewable energy into its operations. Energy Toolbase and BPi installed three BYD battery systems integrated with the ETB Controller energy management system at the winery. The deployment of the advanced energy storage system is designed to reduce demand charges, circumvent network limitations and optimize energy consumption under the region’s time-of-use (TOU) billing rates. The project also focuses on a 980 kWAC export limit imposed by…

Researchers in the US tested the degradation of antimony chalcogenide solar cells exposed to proton radiation. The result indicated robust tolerance and potential for use in space. December 3, 2025 Valerie Thompson Researchers from the University of Toledo and Auburn University in the US have assessed how well antimony chalcogenide-based solar cells can withstand levels of proton radiation at levels typically experienced by solar arrays in space orbit. Prior to the research, the team noted the potential to use this type of thin-film solar cell technology in future land and space photovoltaic applications. “Antimony chalcogenide-based solar cells have received much…

SP Electricity North West has started testing an “innovative” smart energy trading project designed to reduce renewable energy constraints. The BITraDER project is designed to introduce a bilateral energy trading market to allow “large connected customers” to trade their curtailment obligations – the order in which they are asked to curtail their production during times of high network demand. SP Electricity said the project would make it easier for renewable energy projects to connect to the grid and create new revenue opportunities for renewable energy producers. Participants can trade their position in the curtailment queue, which is usually led by…

Researchers in China have developed a new compressed air energy storage system that uses flooded roads in abandoned coal mines to store compressed air and heat for nighttime power generation. Simulations show that the design can achieve a thermal efficiency of 71.5%, stable performance and higher energy density at greater depths, with minimal long-term effects of air leakage. December 3, 2025 Lior Kahana An international group of researchers led by scientists from China’s Chongqing University has developed and thermodynamically assessed a new compressed air energy storage (CAES) system that uses the roads of abandoned coal mines for underground storage. The…

A study published in Science Bulletin describes a solar-powered system that produces freshwater while simultaneously capturing boron from seawater and brine using a composite gel identified as (MXene-MgO)@sodium alginate (MMS). The work focuses on the interconnected pressures on water, food and energy supplies in regions such as Yemen, Pakistan and Haiti, where demand is rising and water scarcity and hunger are severe. Conventional desalination can provide drinking water, but standard processes often do not meet World Health Organization restrictions for boron in drinking water and usually discard boron rather than recovering it as a resource. To address these limitations, the…

Civil robotics has launched a new AI-powered material distribution system for the solar industry. CivNav accelerates solar construction by streamlining logistics, efficient stacking and pallet placement, and advanced planning and workflow segmentation. “We’re seeing some really exciting technology entering the industry to solve long-standing inefficiencies,” said Tom Yeshurun, CEO and co-founder of Civ Robotics. “The most important element for us is to keep it simple and accessible, so that everyone in the workplace can benefit from new developments, regardless of their experience level. As we continue to build new robotic systems, we ensure that innovation and user experience always go…
