LONGi sets multiple world records for solar cell conversion efficiency: Perovskite/Silicon tandem type 34.85%, crystalline silicon (single junction type) 27.81% - holding dual crowns for tandem (multi-junction) type and single junction type crystalline silicon.

LONGi announced that in April 2025, it set a world record for conversion efficiency at 34.85% for tandem (multi-junction) solar cell technology using perovskite and crystalline silicon, as well as 27.81% for single-junction crystalline silicon solar cells. With this achievement, LONGi has secured a double world record in both categories, once again demonstrating its technological innovation at the forefront of the industry.
The achievement of this world record in conversion efficiency for perovskite/silicon tandem solar cells marks the third time since reaching 33.9% in November 2023 and 34.6% in June 2024.
Additionally, in the traditionally used single-junction crystalline silicon solar cells, this record achievement follows the industry's first update in five years to 26.81% in November 2022, and subsequent updates to 27.09% in December 2023 and 27.3% in May 2024, marking the fourth consecutive record update over four years.
The record updates are not the goal but a milestone towards the future. LONGi's research and development team will continue to pursue innovative research and development with the mission of "creating a world of green energy using solar energy."
