according to an official announcement from LONGi Green Energy, the crystalline silicon-tenbergite laminated battery developed by LONGi Green Energy was recently certified by the U.S. National Renewable Energy Laboratory (NREL), with an efficiency of 33.9%, setting a new record for this battery. World record for efficiency. This study is the first time that the efficiency of a crystalline silicon-perovskite tandem cell exceeds the Shockley-Quisser (SQ) theoretical efficiency limit of single-junction cells of 33.7%, providing a significant contribution to demonstrating the efficiency advantages of tandem cells over single-junction cells.
