Trina Solar builds PV Factory For Stronger N-Type Value

Trina Solar has started construction of the Trina Solar New Energy Industrial Park in Xining, the capital of China’s Qinghai province. The industrial park will cover almost the entire PV manufacturing chain from polysilicon production through to finished modules based on 210 and n-type technology

10GW n-type modules on the way, for higher customer value

The factory will include production lines with an annual output of: 300,000 tonnes of industrial silicon; 150,000 tonnes of high-purity polysilicon; 35GW of monosilicon; 10GW of wafer slices; 10GW of cells; 10GW of modules and 15GW of auxiliaries for modules. The industrial park’s development will be in two phases. For phase one, the expected annual output of industrial silicon will be 100,000 tonnes; high-purity polysilicon 50,000 tonnes; monosilicon 20GW; wafer slices 5GW; cells 5GW; modules 5GW; and auxiliaries 7.5GW. Phase one is due to be completed by the end of 2023. In phase two, the expected annual output of: industrial silicon will be 200,000 tonnes; high-purity polysilicon 100,000 tonnes; monosilicon 15GW; wafer slices 5GW; cells 5GW; modules 5GW; and auxiliaries 7.5GW. Phase two is due to be completed by the end of 2025. As the industry rapidly moves towards a new stage of n-type, in line with the company’s strategic development, an industrial chain needs to be established to further improve industrialization of next-generation n-type cell technology, guide the industry towards switching to n-type and create greater value for customers.

Trina Solar leads n-type technology with solid reservoir of expertise

The Trina Solar State Key Laboratory of PV Science and Technology of China has set world records. Four years ago, it was selected as a demonstration enterprise for China’s ‘Top Runner’ program, with n-type TOPCon technology. In the early stages Trina’s 500MW pilot line has achieved a world record of 25.5% for efficiency, with industryleading mass production efficiency. In addition, the 8GW n-type production line is running smoothly. Trina Solar has set world records 23 times, and the company has built a huge reservoir of expertise and technical assets, for example: heterojunction technology, interdigitated back contact (IBC) solar cell technology, and perovskite solar cell technology. Trina Solar will continue to innovate, provide highly reliable and high-value products to global customers, and promote green energy development worldwide.
