Modules & Upstream Manufacturing

China-based PV equipment supplier Ideal Energy (Shanghai) Sunflower Semiconductor has completed an AI-enabled pilot line for ultra-thin, flexible heterojunction (HJT) solar cells, targeting lightweight power systems for space and near-space applications.

Rising silver prices are pushing PV manufacturers toward copper-based metallization, with DK Electronic Materials targeting 2026 for large-scale deployment of high-copper paste solutions, while Fraunhofer ISE warns efficiency trade-offs remain unacceptable.

Researchers in Spain have tested the erosion resistance of common galvanized coatings using both free-falling sand and forced-air sand-impingement methods. The study found that continuously galvanized steel coatings showed the lowest erosion rates, outperforming HDG and Zn-Al-Mg coatings.

The U.S. federal patent office rejected separate challenges from JinkoSolar, Canadian Solar and Mundra Solar to invalidate intellectual property that First Solar claims is fundamental to the manufacturing of crystalline silicon solar cells.

United Solar Holding has secured more than $900 million to complete the financing required for its 100,000 MT polysilicon manufacturing facility in Oman. Production is expected to begin during the first quarter of this year.

WFES 2026 in Abu Dhabi underscored growing momentum for solar, storage, and C&I renewables across MENA, with batteries emerging as a key enabler for grid stability, agriculture, and data centers. Industry leaders pointed to Iraq, Libya, Yemen, and Saudi Arabia as key growth markets, highlighting rising interest in AI-driven data centers, solar-plus-storage solutions, and a broadening regional supply chain.

China-based metallization paste supplier DK Electronic Materials says a major unnamed customer has adopted its high-copper metallization paste for gigawatt-scale solar cell production, combining copper paste with a seed-layer silver paste compatible with n-type and tunnel oxide passivated contact (TOPCon) 3.0 processes.

Researchers have used multivalent amidinium ligands to boost perovskite solar cell efficiency to 25.4%, achieving over 95% stability after 1,100 hours at 85  C. The proposed approach enables controlled low-dimensional passivation layers, offering a practical route for durable, large-area perovskite devices.

The Australian scientists designed the cell with a sodium sulfide additive to achieve uniform sulfur and selenium distribution, improving charge transport.
This controlled elemental layering reduces energy barriers and defects, enabling a certified efficiency of 10.7%.

Silver prices hit a record $94.73/oz on January 19. Silver analyst Philip Newman tells pv magazine the metal could soon surpass $100/oz, increasing pressure on PV module manufacturers to reduce silver usage.
