Longi sets world records for silicon solar cell and module efficiency

Solar giant Longi Green Energy Technology Co announced two major technological breakthroughs, setting new world records for the conversion efficiency of both its crystalline silicon solar cells and modules.

The company's self-developed Hybrid Interdigitated-Back-Contact (HIBC) solar cell achieved a photoelectric conversion efficiency of 28.13 percent, according to an authoritative certification by the Institute for Solar Energy Research Hamelin (ISFH) in Germany.

The milestone marks another significant stride toward the theoretical efficiency limit of crystalline silicon solar cells, surpassing the company's previous record of 28.04 percent set in January 2026.

Longi also announced that its solar module — based on HIBC cell technology — reached an efficiency of 26.4 percent. Certified by the United States-based National Renewable Energy Laboratory (NLR, formerly NREL), the achievement breaks the company's prior module efficiency ceiling of 26 percent, it said.

Technological advancements by Chinese PV firms like Longi are crucial for driving down the levelized cost of electricity derived from solar power, making it an even more competitive and attractive energy source globally.

The company remains committed to developing groundbreaking technology and relentlessly driving improvements in converting solar energy to electricity in order to produce green, renewable, and cost-effective photovoltaic energy, it said.
