This is the best summary I could come up with:
Longi said this week that it has achieved a power conversion efficiency of 33.9% for a perovskite-silicon tandem solar cell.
The company said that NREL has confirmed the results, which represent a world record for this cell typology.
The previous record was held by Saudi Arabia's King Abdullah University of Science and Technology (KAUST), which achieved a 33.7% efficiency for a device with the same configuration in June.
“The theoretical efficiency of perovskite-silicon tandem cells is 43%, which makes them the most feasible alternative to current mono-junction silicon cells,” said Longi President Li Zhenguo, without providing technical details.
The European Solar Test Installation (ESTI) certified the results, which represented a significant increase on its previous 31.8% efficiency rating, which was announced during the SNEC conference in late May in Shanghai, China.
Longi has broken the world record for solar cell efficiency 15 times since April 2021.
