LONGi, a global powerhouse in solar technology, has just achieved a stunning breakthrough. The efficiency of LONGi's proprietary dual terminal perovskite-silicon tandem solar cell now stands at 34.85%, smashing the previous world record for perovskite-silicon tandem cells, and the result has been certified by the US National Renewable Energy Laboratory (NREL).

Perovskite-silicon tandem solar cells are considered to be the frontrunners for the next generation of ultra-efficient solar technology. Their theoretical maximum efficiency is a remarkable 43%, dwarfing the 33.7% SQ limit of single junction solar cells.

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%, a true testament to the prowess of LONGi's R&D Institute.

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.
