DKEM seeks $57.5 million in twin patent suits against Chinese PV rivals
Wuxi DK Electronic Materials is pursuing two patent infringement cases against domestic competitors, seeking injunctions, equipment destruction, and combined damages of CNY 400 million ($57.5 million).
Chinese PV Industry Brief: Polysilicon output set to fall by 15% in January
Polysilicon trading in China remained largely inactive, with production cuts accelerating and wafer prices falling week on week, while downstream cell prices continued to rise and module prices held steady, according to a trade group representing China’s nonferrous metals sector.
Study finds much lower-than-expected degradation in 1980s and 1990s solar modules
Researchers at SUPSI found that six Swiss PV systems installed in the late 1980s and early 1990s show exceptionally low degradation rates of just 0.16% to 0.24% per year after more than 30 years of operation. The study shows that thermal stress, ventilation, and material design play a greater role in long-term module reliability than altitude or irradiance alone.
TOPCon cell prices rise for fourth week amid elevated silver costs and export rebate uncertainty
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Power Roll testing new metrology for perovskite solar
The UK-based perovskite solar PV specialist has announced a new metrology research project with Swansea University and a new development agreement with Renolit, a German plastic films, sheets and polymer solutions company.
Silver price surge shows no signs of slowing, hitting a new all-time high of $117.66 per ounce
Silver hit a new all-time high of $117.66/oz, climbing over 40% in the past month and 275% in the past year, driven by dollar weakness, geopolitical tensions, and gold’s strong momentum. Silver analyst Matthew Piggott tells pv magazine the metal may reach $130/oz within a couple of weeks.
Korean scientists build mini perovskite solar module with 22.56% efficiency
GIST researchers have developed a perovskite mini-module with 22.56% efficiency by improving the SnO₂ electron transport layer with PEI, reducing defects and electron loss. The module retained 94% of its performance after 500 hours, highlighting potential for scalable, stable perovskite solar cells and modules.
Flexible perovskite solar cells with tunable color, transparency
Researchers at Hebrew University of Jerusalem have demonstrated 9.2% efficient printable semi-transparent, flexible halide perovskite solar cells with tunable color and transparency.
U.S. authorities find no definitive evidence of hidden devices in Chinese solar inverters
New documents reveal US government found only two cases of communications in Chinese inverters that differed from official documentation. The discrepancies were deemed “non-malicious” and “non-intentional” by investigators.
Chinese startup claims record-breaking 27.87% efficiency for single-junction perovskite solar cell
Shenzhen-based SolaEon has reported a 27.87% efficiency for a single-junction perovskite solar cell on a 0.076 cm² lab device, certified by China’s National Photovoltaic Industry Metrology and Testing Center.
