India, April 22 -- The world's leading solar technology company, LONGi, has made another significant breakthrough in solar cell R&D. LONGi independently developed a two-terminal crystalline silicon-perovskite tandem solar cell that has achieved a conversion efficiency of 34.85%, certified by the U.S. National Renewable Energy Laboratory (NREL), once again breaking the world record for crystalline silicon-perovskite tandem cell efficiency.

As a leading technology pathway for next-generation ultra-efficient solar cells, crystalline silicon-perovskite tandem solar cells boast a theoretical efficiency limit of 43%, far surpassing the Shockley-Queisser (SQ) limit for single-junction solar cells (33.7%). LONGi's tandem solar cell R&D team has ...
