Trina Solar has revealed that its 210×210mm i-TOPCon cell has achieved maximum efficiency of 25.5 percent, setting a world record for the 23rd time.
The result was certified by the National Institute of Metrology of China, a metrology scientific research center 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 tunneling 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 percent. 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.
In February Trina Solar was named by Reuters Events as one of the top 100 innovators in Global Energy Transition 2022.
