LONGi Shatters Solar Cell Efficiency Record at 26.12%
LONGi has shattered another efficiency record for gallium-doped p-type heterojunction (HJT) solar cells, reaching an impressive 26.12%. The Institute for Solar Energy Research Hamelin (ISFH) has confirmed this new milestone.
LONGi's research team has been relentless in pushing the boundaries of solar cell efficiency. In 2025, they improved the manufacturing process of p-type HJT solar cells, boosting the conversion efficiency from 25.47% to the current record of 26.12%. This remarkable feat was published in the same year.
The company's commitment to innovation is evident in its track record. In 2021 alone, LONGi broke conversion efficiency records seven times. Building on this momentum, LONGi achieved an efficiency of 25.47% in March 2023, paving the way for the latest record.
The new record of 26.12% efficiency demonstrates LONGi's continued leadership in solar cell technology. The development process of the cell is similar to that of n-type cells, showcasing versatility and stability. LONGi's research team has also enhanced the wafering process for improved resistivity and lifespan of solar cells, further solidifying their position in the industry.
