Trina Solar has set a world record for solar module efficiency of 25.44%, independently verified by Fraunhofer ISE’s CalLab. Chinese PV module manufacturer Trina Solar has announced that it has achieved a power conversion efficiency of 25.44% on a fully passivated n-type heterojunction (HJT) solar panel. The CalLab at the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) independently verified the result, which is a world record for a large-area crystalline silicon solar panel with front and back contact structures. Trina said the achievement represents its 30th world record for solar efficiency and sets a new benchmark for the PV industry. The company added that the result beats the previous record of 25.40% held by Chinese competitor Longis rear contact (BC) modules. The module was developed at Trina’s National Key Laboratory of PV Science and Technology in China. It incorporates industrial-grade 210 mm x 105 mm phosphor-doped n-type silicon wafers, combining advanced passivation techniques, back-side HJT technology and multi-frequency RF processes. Key innovations include light-trapping structures, ultra-dense packaging and low-resistance interconnects, resulting in superior optical and electrical performance, according to the company. “This record is a testament to our relentless commitment to research and innovation,” said Gao Jifan, Chairman and CEO of Trina. “We will continue to invest in the development of passivated contact cells and modules to maintain our leadership in solar technology.” This achievement underlines Trina’s commitment to HJT technology, which has gained traction as a high-efficiency alternative to traditional TOPCon and PERC technologies. In the past four months, Trina has set two world efficiency records for TOPCon cells and one for HJT cells. In December, it achieved a world record efficiency of 27.08% for a fully passivated n-type HJT device and the result was verified by the Institute for Solar Energy Research in Hamelin (ISFH CalTEC). Previously, in October, it announced a 25.9% efficiency for a large-area industrial TOPCon solar cell, and a month later it achieved a 26.58% efficiency for the same cell technology, with both results certified by ISFH CalTeC. |
