A LONGi announced in Xi'an, Shaanxi Province, China, that it has achieved a world record efficiency of 26,81% for its HJT solar cells, based on a full-size silicon wafer, through mass production.
According to the manufacturer, the result was confirmed by ISFH (Institute for Solar Energy Research – Hamelin Solar Energy Research Institute) in Germany.
At the ceremony, Martin Green, professor at the University of New South Wales, Australia, and creator of the “solar cell efficiency tables”, said that the result is the highest efficiency record for silicon photovoltaic cells to date.
“Improving efficiency and reducing LCOE (levelized cost of energy) is the eternal theme of industry development. Solar cell efficiency is the beacon of photovoltaic technology innovation,” highlighted Li Zhenguo, founder and president of LONGi.
According to him, every 0.01% improvement in conversion efficiency requires enormous efforts. “In particular, crystalline silicon solar cells represent almost 95% of the current photovoltaic market,” he highlighted.
Xu Xixiang, vice president of LONGi Central R&D Institute, emphasized that breaking the world record was a milestone in the history of China's photovoltaic industry, which not only fully demonstrated the scientific and technological strength of enterprises, but also increased confidence and determination of the country in becoming an important player in the world.
Efficiency records
Since June 2021, LONGi's R&D team has continuously broken the world record for HJT solar cell conversion efficiency, increasing from 25.26% to 26.81%, up 1.55% in one year and four months.
