Trina Solar has achieved a world record 25.44% power conversion efficiency for its n-type fully passivated heterojunction (HJT) solar panel. The milestone was independently verified by the CalLab at Fraunhofer ISE, marking the highest efficiency for a large-area crystalline silicon solar module with front-and-rear contact structures.
This achievement surpasses the previous 25.40% record held by Longi’s back-contact modules and represents Trina’s 30th world record in solar efficiency. The module, developed at Trina’s National Key Laboratory of PV Science and Technology in China, utilizes advanced passivation, light-trapping structures, ultra-dense encapsulation, and low-resistance interconnections for enhanced optical and electrical performance.
Trina’s CEO, Gao Jifan, emphasized the company’s dedication to research and innovation, particularly in HJT technology, which offers a high-efficiency alternative to TOPCon and PERC technologies. In recent months, Trina has set multiple records in solar cell efficiency, further solidifying its leadership in photovoltaic advancements.
