On June 11, LONGi officially launched its newly developed HIBC technology and mass-produced module products at SNEC 2025. The HIBC technology sets a new industry precedent by being the first to achieve a power output exceeding 700W using the golden dimension of 2382mmX1134mm, with module efficiency approaching 26%, ushering in the “25%+ era” for photovoltaic module efficiency.
HIBC technology, which combines the characteristics of HJT and BC technologies, has achieved large-scale module production globally for the first time.
At the launch event, LONGi Green Energy’s Chairman Zhong Baoshen stated that this represents another milestone in LONGi’s technological innovation and a significant breakthrough in its BC technology roadmap.
In April 2025, the HIBC cell achieved a conversion efficiency of 27.81%, certified by the Institute for Solar Energy Research Hamelin (ISFH) in Germany, setting a new world record.
Zhong Baoshen emphasized that conversion efficiency is not only a beacon for photovoltaic technology but also the lifeblood of photovoltaic products. LONGi has consistently advocated within the industry for “increasing power output per unit area or standard size, thereby enhancing yield.” “Simply increasing efficiency through physical stacking or area expansion offers limited customer value; moreover, the reliability and quality risks become apparent with larger sizes,” Zhong noted.
Despite LONGi’s HPBC2.0 products already leading the market—with 72-cell standard-sized modules consistently outperforming TOPCon products by 30W—the company has not ceased its technological and product development efforts.
The newly introduced HIBC technology products achieve a power output exceeding 700W with the golden dimension of 2382mmX1134mm, featuring a power density exceeding 259W/㎡ and module efficiency reaching 25.9%. “This is currently the world’s most efficient industrialized photovoltaic product, truly unifying high value and reliability through improved yield,” Zhong Baoshen said.
During the launch event, LONGi’s 700W HIBC modules were also officially unveiled.
LONGi Chairman Zhong Baoshen and President of LONGi’s Distributed Business Group Jiang Dongyu jointly unveiled the 700W HIBC modules.
Compared to other 700W modules in the industry (which typically measure 2384mmX1303mm), this module is 0.4㎡ smaller in area but boasts a higher power density of 34W/㎡, shattering the industry’s conventional logic that “larger sizes lead to higher power.”
