BEIJING (Reuters) – China's Trina Solar has set a new world record for the conversion efficiency of a particular type of solar module, the company said in a statement on Monday.
In laboratory tests, Trina n-type fully passive heterojunction (HJT) full-surface models showed an efficiency of 25.44%, according to results verified by the Fraunhofer CalLab in Germany, a solar research group.
Passivation is a technology that covers defects on the surface of a solar cell, and cell efficiency refers to the percentage of solar energy hitting a device that is converted into usable electricity. use Increasing cell efficiency can help reduce the size needed for solar installations as well as cut costs.

Professor Martin Green at the University of New South Wales in Sydney, whose laboratory has held the solar cell efficiency record for decades, said the result demonstrated the potential of HJT solar technology, one of several is set to be the key next generation technology for the sector. .
“In the long run it's about efficiency, so even if some lines are currently more expensive than others, what tends to happen when the industry comes to new technology is that “The cost is coming down very quickly,” Green told Reuters.
Trina's chairman and CEO, Gao Jifan, said the company will continue to increase its research and development in passive solar technology to maintain its technological leadership.
HJT remains a small percentage of the market, estimated by solar consultancy InfoLink to account for 7% of high-efficiency solar cell capacity in 2024, 8% in 2025 and 9% in 2026. TopCON cells, or tunnel function passive communication, are cells. it is expected to make up the majority of the market over the next five years.
In addition to representing a record for HJT technology, the results are a new milestone for the photoelectric conversion efficiency of single-crystalline solar cell modules, Trina said in the statement.
