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.
Saudi Arabia launches qualification process for 12 GWh of battery storage projects
The program comprises six projects with a cumulative power output of 3 GW, each designed to provide four hours of storage duration.
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.
