Researchers in Brazil tested second-life polycrystalline PV modules for two years and found they retained 87–88% of their original power, with minimal degradation and stable performance. Despite strong sustainability and circular economy benefits, economic incentives remain limited due to the declining cost and short warranties of new state-of-the-art silicon PV modules.

JinkoSolar has formally terminated its 4 GW Hai Ha solar cell project in Vietnam, citing US antidumping duties that undermined its export economics. The company will maintain other Vietnamese operations while shifting focus to localized supply chains and Asia-Pacific and Middle East markets.

Premier Energies Ltd has commenced trial production at its 5.6 GW solar module manufacturing facility in Seetharampur, Telangana. The new facility produces G12R TOPCon modules with zero busbar (0BB) architecture.

Researchers in Singapore have developed fully vacuum-processed ultrathin perovskite solar cells with absorber layers as thin as 10 nm, achieving high transparency and stable efficiencies up to 12%. These cells balance optical transparency and electrical performance, offering scalable, design-flexible photovoltaics suitable for seamless integration into buildings.

Tongwei is partnering with GS-Solar and Golden Solar to develop a large-scale manufacturing facility for hybrid heterojunction back-contact (HBC) solar cells that combine heterojunction passivation, tunneling oxide and polysilicon structures used in TOPCon designs, and the grid-free front-side architecture typical of back-contact technologies.

Researchers in Sweden developed a bifacial chalcoprite solar cell using a titanium-doped indium oxide (ITiO) back contact, achieving 68% bifaciality. The device is able to maintain strong front-side performance with around 15% efficiency, 595 mV open-circuit voltage, and 75% fill factor.”

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.

The result was certified by China’s National Photovoltaic Industry Metrology Test Center (NPVM). The cell utilizes a perovskite top device with MBT-ligand-controlled crystallization on a TOPCon silicon bottom cell, achieving a void-free, high-efficiency tandem structure.

The Terawatt PV 100 ranks the top 100 solar manufacturing companies using a new methodology based on production scale, financial strength, and corporate transparency, with Tongwei leading the Q1 2026 list and most top firms headquartered in China. The analysis highlights increasing global supply-chain scrutiny driven by tariffs and ESG mandates, while also showing rising influence from Indian companies and strong positions for key materials and equipment suppliers.

Job advertisements on Tesla’s website outline the 100 GW ambition and follow reports the company is in talks with Chinese firms for the purchase of $2.9 billion worth of equipment for solar manufacturing.
