LONGi Green Energy Technology Co. Ltd.

This award recognises LONGi Green Energy Technology Co., Ltd. for achieving two new world records in solar cell efficiency in 2025, certified by the US National Renewable Energy Laboratory: a 33 % conversion efficiency for a commercial‑size (260.9 cm²) silicon‑perovskite tandem solar cell and a 26 % efficiency for a crystalline silicon module.

These breakthroughs directly lower the levelised cost of electricity from photovoltaics, making solar power more competitive and accelerating its deployment as a primary energy source. Each percentage point of efficiency gain reduces the land area, materials and balance‑of‑system costs required to displace fossil‑based generation, turning incremental laboratory records into exponential decarbonisation leverage.

Beyond its efficiency milestones, LONGi is embedding emissions reduction into its own operations, having lowered Scope 1 and 2 emissions by 37 % between 2023 and 2024, and now aims for a 60 % reduction from 2020 levels. By pushing the efficiency frontier of both single‑junction silicon and next‑generation tandem cells while simultaneously cutting its manufacturing footprint, LONGi proves that technological leadership and decarbonisation are inseparable. For making solar energy the world’s most economical and rapidly deployable zero‑carbon power source, LONGi receives this recognition.
