Tech Breakthroughs: World Records Redefine Industry Standards
At SNEC 2025, LONGi’s crystalline silicon-perovskite tandem solar cell achieved a groundbreaking 33% efficiency on a large area of 260.9 cm² through material innovation and structural optimization. This marks a nearly 20% efficiency gain over single-junction silicon solar cells and represents the world’s first 33% efficiency milestone at mass-producible dimensions – paving a new path for reducing photovoltaic energy costs. Simultaneously, the 26% efficiency of its back-contact (BC) modules demonstrates LONGi’s profound expertise in this technology, propelling crystalline silicon module efficiency toward the 27% threshold.
As a trailblazer in PV industry, LONGi has consistently driven technology innovation. From revolutionizing the industry by mainstreaming monocrystalline technology over polysilicon, to pioneering perovskite and BC solar cell research, the company has built an end-to-end R&D ecosystem spanning materials, equipment, and manufacturing processes.
"LONGi’s innovation genes stem from reverence for technological fundamentals," stated Li Zhenguo, Founder of LONGi, President of its Central R&D Institute, and the company’s newly appointed CTO. "We focus not only on our own breakthroughs but champion collaborative innovation."
These weighty world records have been formally included in the 66th version of the Solar Cell Efficiency Tables. Curated by Professor Martin Green and a global panel of leading scientists, this authoritative benchmark has been published in Progress in Photovoltaics since 1993 and is recognized as the "gold standard" for tracking PV advancements.
Innovation Genes: From Cell Technology to Collaborative Ecosystems
At the new starting point of its 25th anniversary, LONGi unveiled a dual-engine "Innovation + Collaboration" strategy: intensifying R&D in frontier fields like BC, perovskite, and hydrogen energy while building an open innovation ecosystem with global partners. As Li Zhenguo stated, "The era of photovoltaics as a dominant energy source has arrived, yet challenges like energy storage and grid integration remain. Only through collaborative innovation can clean energy truly benefit everyone."
