Trina Solar’s First 210 mm Module Rolls off Production Line

Trina Solar has announced the 1st large-size module that deploys the 210 mm silicon wafer (210 module) formally rolled off the company’s production line

Trina Solar has announced that the first large-size module that deploys the 210 mm silicon wafer (210 module) developed by the company formally rolled off the company’s production line. The firm claims to lead the industry in the Research and Development (R&D) and manufacturing of 210 modules. The move will greatly accelerate the time-to-market for large-size modules.

Trina Solar had initiated the R&D of 210 modules last year. Based on the company’s leading multi-busbar technology, the first 210 module adopts an innovative 1/3-cut design. Based on a comprehensive consideration of potential challenges including strong module power, yield, manufacturing difficulties, hot spot risks, output current performance and junction box safety, Trina Solar’s multi-busbar and 1/3-cut design will pave the way for the compatibility and integration of large-size, high-power modules, and downstream systems.

The head of engineering technology R&D at Trina Solar said, “With decades of accumulated experience in process and technology, we are confident that we can leverage the latest materials and technologies to create another high-performance and the reliable module for the photovoltaic (PV) industry. Currently, our team is accelerating the transformation of our latest R&D outcomes into products that can go into mass production, leading the PV industry into the era of 500W module power.”

In November 2019, the firm had announced that its State Key Laboratory (SKL) of PV Science and Technology (PVST) of China has set a new world record of 23.22 percent for a high-efficiency large-area quasi-monocrystalline n-type (c-Si) i-TOPCon solar cell.

The record-breaking n-type bifacial i-TOPCon solar cell was fabricated with a low-cost industrial process of advanced i-TOPCon (Industrial Tunnel Oxide Passivated Contact) technologies, on a large-sized phosphorus-doped Cast-mono Si substrate. The 247.79 cm2 bifacial solar cell reached a total-area front side efficiency of 23.22 percent. This result has been independently confirmed by the ISFH CalTeC in Germany.
