Sunoyster offers lightweight 440 W glass-covered TOPCon PV panel
Germany-based solar tracker developer Sunoyster Systems has developed a 440 W lightweight solar panel with a tempered glass cover for low-load commercial and industrial roofs.
Centrotherm launches new high-volume TOPCon PECVD tool
The Germany-based PV thermal process equipment and technology provider has launched c.Plasma Q Max to process up to 10,000 wafers per hour in high-volume TOPCon solar cell manufacturing lines.
India’s GREW Solar secures 550 MW repeat module order from IPP
Indian module manufacturer GREW Solar has won a 550 MW repeat supply order from an independent power producer (IPP), with deliveries of tunnel oxide passivated contact (TOPCon) modules scheduled to be completed by March 31, 2026.
Astronergy adopts quarter-cut cell design, boosting TOPCon module efficiency and reliability
The company’s new ASTRO N7 Pro PV modules achieve 2% higher cumulative energy yield over the project lifecycle compared to conventional previous-generation modules, according to Astronergy Head of Global Product Management Baohua He.
UNSW researchers identify new damp heat-induced failure mechanism in TOPCon solar modules
UNSW researchers identified a new damp-heat degradation mechanism in TOPCon modules with laser-fired contacts, driven primarily by rear-side recombination and open-circuit voltage loss rather than series-resistance increase. The study highlights that magnesium in white EVA encapsulants accelerates degradation, guiding improved encapsulant and backsheet selection for more reliable modules in humid environments.
Not all POE encapsulants protect TOPCon solar cells from corrosion
UNSW researchers found that some POE encapsulants can trigger severe corrosion in TOPCon solar modules, causing up to 55% power loss under damp-heat conditions. Their study highlights that module reliability depends on the exact encapsulant formulation, not just the polymer type.
China solar manufacturer Eging faces potential exit from flagship PV project
A regional government authority in eastern China is weighing whether to unwind a multibillion-yuan manufacturing joint venture with Eging PV after construction delays and funding disruptions, underscoring mounting strain across the country’s solar supply chain.
India’s Emmvee Energy signs 4.5 GWp TOPCon solar cell supply agreement
Emmvee Energy has signed a long-term supply agreement with a domestic buyer to deliver 4.5 GWp of tunnel oxide passivated contact (TOPCon) solar cells.
‘Back contact will reach cost parity with TOPCon before end of decade’
During a pv magazine Week Europe 2025 webinar, panelists forecast back contact (BC) solar cells’ market share will draw level with TOPCon towards the end of the decade, before tandem technology begins large-scale momentum in the early 2030s.
India’s Vikram Solar commissions 5 GW automated module plant
Vikram Solar says its new 5 GW Vallam facility in Tamil Nadu lifts its module manufacturing capacity to 9.5 GW and is built on tunnel oxide passivated contact (TOPCon) technology with future heterojunction upgrades.
