Manufacturer Trina announced that its 210mm × 210mm i-TOPCon cell achieved 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, a scientific metrology research center and national legal metrology technical institution.
According to the manufacturer, Trina Solar researchers have resolved technical problems related to the selective boron emitter, large-area tunneling silicon oxide and on the preparation of doped polysilicon and high-efficiency hydrogen passivation.
The solutions were developed at State Key, the company's Photovoltaic Science and Technology Laboratory.
Also according to Trina, researchers have brought the maximum efficiency of large 210mm N-type monocrystalline cells to 25.5% when using mass production cell equipment.
“We are extremely proud of these latest achievements,” said Chen Yifeng, head of the company's high-efficiency cell and module R&D center. “Trina Solar is fully committed to cutting-edge research and development, and has been a pioneer in technological production and manufacturing, helping it maintain its leadership position with its efficient products”, he points out.
The achievements were vital as the company continued with its 210mm N-type i-TOPCon high-efficiency cell design and paves the way for follow-up development in the high-end market.
Furthermore, Trina Solar's results were widely well received in the sector, including by renowned authorities and institutions. In February, Trina Solar was named by Reuters Events as one of the Top 100 Innovators in Global Energy Transition 2022. The company was the only Chinese-listed company on the list and among only a few others in the Asia Pacific region to appear on it.
Over the years, Trina Solar has applied for 2,200 patents, becoming the industry leader in this regard. Furthermore, the company has played a key role in 107 industry standards and published 96 standards, making a huge contribution to advances in photovoltaic technology.
