Voltfang has opened what it claims is the largest battery storage factory in the second life in West Germany, with 250 MWh annual capacity expected in 2026 and a target of 1 GWh before 2031. August 22, 2025 Sandra Enkhardt By ESS News Voltfang has officially opened its ‘future FAB’ production site in Aachen, Germany. The factory will produce second-life battery storage systems for industrial, commercial and large-scale applications. The company said that the annual production capacity will reach 250 MWh next year and rises to 1 GWh before 2031. It claimed that the Fab-op de Triwo Technopark Aachen, at…

A Chinese-Japanes research team has developed a new laser technology for the micro-turning of transparent and hard materials for solar cell packaging. The process is based on a silver ion solution that is said to be able to achieve high -quality connections. August 22, 2025 Valerie Thompson Researchers from the Heei University of Science and Technology in China and Riken Center for Advanced Photonics in Japan showed a new Silver Ion Solution Support Femtosecond Laser process for welding process from glass to glass with the aim of ultimately applying it to solar cell packaging. The team demonstrated the strength of…

Ocean Technology Company, based in the US, has developed a series of data-collected unspanded surface vehicles (USV) that are powered by solar and wind. They are designed to operate in hard maritime conditions, above and below the sea surface, to perform science, commercial and defense missions. August 21, 2025 Valerie Thompson Saildrone Inc., an American ocean technology company, has developed an ocean fleet Unwritten surface vehicles (USV) That depend on solar and wind energy to collect autonomously sensor and camera data and process it over long-term maritime missions above and below the sea surface. All Saildrone vehicles rely on solar…

Prototype system transforms urine into solar energy driven fertilizer and clean water A Team led by Stanford has developed a prototype that converts urine into fertilizers while also electricity is generated and the sanitary facilities improves. The system, detailed in natural water, restores ammonia with the help of solar energy and conquered waste heat and offers a decentralized solution for agriculture and energy in areas with limited resources. “This project is about converting a waste problem into an opportunity for resources,” says senior author William Tarpeh, university professor of chemical engineering. “With this system we capture nutrients that would otherwise…

The Solar World Congress (SWC) of the International Solar Energy Society (ISES) has been held every two years since the 1970s and will take place in Brazil in November 2025. With the sharp and continuous decrease in the PV costs, Fotovoltaisies has become the cheapest solution in Brazil and worldwide, and this is reflected in the number of accepted articles for presentation at the SWC. The Solar World Congress program is traditionally dominated by presentations on solar radiation and thermal solar applications, but this year Fotovoltaïschens is the focus of the most accepted articles. In Brazil, where large -scale hydroelectric…

The solar market of Serbia at the top 5,000 prosumers in the first half of 2025, although there are no plants above 10 MW online. The country has a gigawatt scale pipeline and has purchased 124.8 MW in the auction of February renewable energy sources. August 21, 2025 Patrick Jowett SerbiaThe cumulative solar capacity has been reached 281 MW, according to figures from the association of renewable energy sources from Serbia (Res Serbia). The association told PV -Magazine The figure consists of 172.7 MW of solar energy plants that are connected to the distribution system operator (DSO) and 109.2 MW…

A research team in Egypt has proposed a new architecture for kesterite solar cells using a copper oxide trees transport layer and optimized configuration. The simulated device had a maximum efficiency of 33.56%. August 21, 2025 Valerie Thompson A research team at Kafrelsheikh University in Egypt has proposed a kesterite solar cell with an optimized copper oxide (CUO) hole transport layer. The simulated device had a maximum efficiency of 33.56%. Kesteriet, in particular copper zinc tin sulfide (CZTS) solar cells, are an attractive candidate for affordable thin film solar cells because of the abundance and non-toxic properties of the cell…

S-5!, A worldwide supplier of metal roof aid, launches A new stock market program To support people who follow training in construction and solar-related fields. Credit: S-5! The S-5! Scholarship will grant $ 1500 to a student who is registered for a construction -related program at a Trade School, Community College or University. The purpose of this fair is to help those who have a passion to contribute to the built environment. “Support for the training of future construction professionals comes in accordance with our mission to lead, serve and give it back to the industry that has shaped us,”…

Stanford University researchers have built a photovoltaic thermal electrochemical comic system that gets nutrients for fertilizers from human urine. They say that the system could offer a cost -effective alternative in regions with limited access to conventional fertilizers. August 21, 2025 Patrick Jowett A Stanford University research team has developed a prototype that uses solar energy to extract nutrients from human urine to create a sustainable fertilizer. They presented the system in “Prototyping and modeling of a photovoltaic -thermal electrochemical comic strip system for distributed urine sough recovery”Available in the research diary Natural water. The prototype uses solar energy via…

An interview with Fraunhofer ISE about new discoveries of ultraviolet relegation risks. August 21, 2025 Mark Hutchins From PV Magazine 6/25 “The Hunt for High Efficiency” Can you provide some background information about recent concerns about the industry around Ultraviolet-induced demolition in PV modules? Since about two and a half years we have been involved in various projects where larger module buyers different modulette types against each other benchmarking in terms of reliability. In this context we realized that there was a strong UV breakdown in laboratory tests for some modules. This came in addition to a few other problems,…
