LONGi Green Energy has once again set a world record with its HIBC silicon solar cell, achieving a conversion efficiency of 27.81%. This significant breakthrough was announced on April 11, 2025, at the company’s facility in Wuhu, Anhui province. The remarkable achievement has been certified through calibration experiments conducted by the German Institute for Solar Energy Research (ISFH).
The development of this technology highlights the evolution of the “physical breakthrough-engineering implementation-commercial loop” model. With this new efficiency record, LONGi's BC cell technology is approaching the theoretical limit of <b>29.4%</b>.
In 2021, LONGi Green Energy initiated a "BC revolution" within the industry, marking the beginning of technological innovation. By 2023, the company announced a full transition to BC technology, accelerating the phasing out of PERC capacity while simultaneously building new BC capacity. The second generation of BC technology was introduced in 2024, accompanied by the launch of the Hi-MO 9 module products designed for centralized applications. As of 2025, the second generation of BC products has entered full-scale production, with the Hi-MO 9 modules receiving significant upgrades.
Through its strategic focus on "technological innovation breakthroughs, large-scale production, and industry ecosystem development," LONGi Green Energy is leading the photovoltaic industry towards a new era characterized by higher efficiency, reliability, and profitability.
