An international research team comprising scientists from Chinese module manufacturer Longi has investigated the resistivity distribution of antimony- and phosphorous-doped wafers used in solar cell manufacturing and have found that they offer comparable mechanical strenght. However, their work also showed that antimony-doped wafers have a more uniform resistivity, with a slight increase near the tail end.

A University of Cambridge-led team of researchers have demonstrated precisely controlled layer-by-layer epitaxial vapor growth of two-dimensional halide perovskite films in an industrially compatible process. Their findings could help develop more thermally stable perovskite solar cells.

Civ Robotics’ artificial intelligence (AI) powered navigation system tool is currently being tested at several large solar parks in the United States. The company says it eliminates the need for manual surveying with a sensor device fitted on a construction machine to guide operators to precisely place piles, pallets and PV modules.

Bangladesh has givern approval to a 220 MW plant in Sonagazi, partly funded by the Islamic Development Bank.

The Swiss group acquired Gamesa Electric’s power electronics business in Spain from Siemens Gamesa. The financial terms of the deal were not revealed.

Dongkuk CM has introduced an ultra-high-reflectivity color steel sheet designed to boost the performance of bifacial rooftop PV systems, increasing solar reflectance to 80–85. The new material also offers enhanced corrosion resistance, long-term durability, and added cooling benefits thanks to its advanced plating and dual-layer design, according to the manufacturer.

The U.S. Trade Representative has extended the exclusion of 178 items from the Section 301 import tariffs that were put in place by the prior administration in 2024. The still standing tariffs include a 50% increase on solar cells.

A coalition of 18 California legislators has formally urged the California Public Utilities Commission (CPUC) to enforce regulations under “Rule 21” regarding the interconnection of customer-sited solar and energy storage systems.

Astronergy and JA Solar ended all global litigation and signed a cross-licensing agreement covering tunnel-oxide passivated contact (TOPCon) solar cell patents, resolving a major intellectual-property dispute affecting markets in Europe and beyond.

Spain’s Institute for the Diversification and Saving of Energy confirmed €827 million ($961.4 million) in European Regional Development Fund co-financing for 133 energy-storage projects with a combined capacity of about 2.4 GW and 10 GWh.
