Trina Solar has announced that its 210×210mm i-TOPCon cell has achieved a maximum efficiency of 25.5%, setting a world record for the 23rd time.

The result was certified by the National Institute of Metrology of China, the preeminent metrology scientific research centre and national legal metrology technical institution.

At the company’s State Key Laboratory of PV Science and Technology, Trina Solar researchers solved technical problems related to selective boron emitter, large-area tunnelling silicon oxide and doped polysilicon preparation, and high-efficiency hydrogen passivation.

By using mass production cell equipment, they brought the maximum efficiency of large 210mm N-type monocrystalline cells to 25.5%. This new efficiency, the result of the company’s continuing innovation and research efforts, demonstrates once again Trina Solar’s prowess in cell 210×210mm i-TOPCon cell technology.

“We are extremely proud of these latest achievements,” Trina Solar head of high-efficiency cell and module R&D centre Dr Chen Yifeng says.

“Trina Solar is thoroughly committed to cutting-edge research and development and has been a pioneer in technological production and manufacturing, helping it to maintain its leading position with its efficient products.”
