Trina Solar claims world’s highest efficiency for silicon solar cells with 28.0%-efficient device
The Chinese manufacturer said its TOPCon-compatible hybrid back-contact solar cell achieved a power conversion efficiency of 28.0%. The result was confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).
Premier Energies unveils 600-630 W all-black TOPCon solar modules
The Indian manufacturer said its new all-black panel series features a power conversion efficiency of up to 23.32% and a bifaciality factor of up to 85%.
Chinese scientists build silver-free heterojunction solar cell with 25.2% efficiency
The research team developed a plasma interface engineering method to improve indium tin oxide layers, solving adhesion, contact resistance, and stability issues for copper electroplating. The optimized process enabled uniform copper metallization and boosted device efficiency to 25.2%, significantly outperforming untreated reference cells.
Chinese solar exports surge 125% in March on policy change rush, not underlying demand acceleration
The Chinese customs data show a March surge as buyers rushed shipments ahead of April’s tax-rebate change.
U.S. government sets preliminary anti-dumping duties on solar imports from India, Indonesia, and Laos
The U.S. Department of Commerce has issued preliminary anti-dumping determinations for three key solar-exporting nations, establishing duties of up to 123% on crystalline silicon photovoltaic cells and modules.
Dutch government grants priority status to planned polysilicon factory
The Ministry of Economic Affairs and Climate of the Netherlands has identified a planned polysilicon factory in the country as of strategic importance under the Net Zero Industry Act.
Chinese PV Industry Brief: DKEM seeks cash injection to scale up gigawatt-level production of copper metallization paste
DK Electronic Materials (DKEM) plans to raise up to CNY 3.0 billion (USD 413 million) via a private placement to fund PV paste, metal powder expansion, R&D, and debt repayment. The company is advancing high-copper PV paste toward volume production for TOPCon 3.0 cells.
Japanese scientists build all-perovskite tandem solar cell with 30.2% efficiency
The four-terminal tandem device relies on FAPbI₃ nanoparticles and a spectral splitting design, combining a 24.4% wide-bandgap top cell and a 21.5% narrow-bandgap bottom cell to reach 30.2% efficiency. The system improves light utilization by directing different wavelengths to optimized subcells.
How BIPV façades behave under enclosure fire conditions
A group of scientists in China constructed a specialized compartment to test the thermal breakage and fallout of BIPV façades under enclosure fire conditions. They examined three different types of BIPV modules and found that tempered-glass PV panels exhibit superior thermal and mechanical resistance to breakage.
