LONGi announced it has set a new world record of 33.9% efficiency of crystalline silicon-perovskite tandem solar cells. This was certified by NREL.
This new record efficiency of 33.9% has surpassed the Shockley-Quieser (S-Q) theoretical efficiency limit of 33.7% of single-junction solar cells for the first time. This provides meaningful empirical data to demonstrate the advantages of crystalline silicon-perovskite tandem solar cells over crystalline silicon single-junction solar cells in terms of efficiency.
The theoretical efficiency limit of crystalline silicon-perovskite tandem solar cells can reach 43%, and it is recognized as the mainstream technical solution to break through the efficiency limit of crystalline silicon single-junction cells.
“LONGi has always been willing to devote more strength to exploring cutting-edge development technologies,” said Zhenguo Li, founder and president of LONGi. “For a long time, we have laid out various technological routes in the R&D sector and collaborated with multiple parties to create efficient models and collaborative innovation mechanisms. This not only builds the ‘moat’ of LONGi, but also helps enterprises cross the industry development cycle. I also call on the entire industry to return to the main track of technological competition and promote China’s photovoltaic industry to continue to lead the world through continuous technological innovation.”
