LONGi hits 34.85% efficiency in perovskite tandem PV technology

LONGi has once again announced a new efficiency record for its proprietary dual terminal perovskite-silicon tandem solar cell - 34.85%, certified by the US National Renewable Energy Laboratory (NREL).

LONGi’s research team is on a roll. In November 2023, they increased cell efficiency to 33.9%. Then, in June 2024, they pushed it up to 34.6%. And now, in less than a year, they’ve catapulted it to 34.85%.

 

Perovskite-silicon tandem solar cells are considered to be the frontrunners for the next generation of ultra-efficient solar technology, with a theoretical maximum efficiency of around 43%. 

This achievement underlines LONGi’s commitment to innovation. As a leading solar company, LONGi will continue to pursue its mission of scientific innovation, using its home-grown technology to drive the global energy transition.
