LONGi continues to innovate around the fundamental technologies of solar photovoltaics and application‑scenario solutions, while intensifying efforts on core technology breakthroughs. The company’s self‑developed HIBC solar cells were recently certified by Germany’s Institute for Solar Energy Research Hamelin (ISFH) with a conversion efficiency of 28.13%, module efficiency based on HIBC cells reaching 26.4%, setting another new record. In addition, as certified by the European Solar Test Installation (ESTI), its self‑developed crystalline silicon‑perovskite tandem solar cells achieved a conversion efficiency of 35.5%, once again breaking the world record for perovskite tandem cell efficiency.
In April, LONGi officially unveiled its “Full‑Stack LONGi ONE” integrated solar‑storage strategy, aiming to deliver the world’s benchmark for efficiency and safety in “solar generators” through fully in‑house developed native integration technologies, completely breaking down the silo effect of solar‑storage systems and providing global customers with unified, efficient and safe green power solutions and asset security.
In the ESG arena, the company has also achieved outstanding results. Through continued deep‑rooted efforts in corporate governance, climate action and nature positivity, it was selected for the 2026 Fortune China ESG Impact List. In the 2025 S&P Global Corporate Sustainability Assessment, it ranked in the top 4% of the semiconductor and semiconductor equipment industry, was included in the 2026 S&P Global Sustainability Yearbook and became the only company in that segment to receive the “Industry Mover” commendation.
