Chinese PV module manufacturer JinkoSolar announced it achieved a power conversion efficiency of 34.82% for a perovskite-silicon tandem solar cell, according to pv-magazine.
The company said the results have been certified by China’s Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences. In its previous attempts, JinkoSolar achieved a cell efficiency of 34.76% for the same device configuration.
“This efficiency breakthrough is attributed to JinkoSolar’s innovations in multiple core technologies, including the dual-layer composite passivation contact structure for N-type TOPCon cells, multidimensional interface passivation technology, gradient crystallization kinetics control strategies, and enhanced optical coupling and light management technologies,” the company said in a statement. “This milestone marks a critical step forward in the industrialization of next-generation perovskite tandem technology.”
No more technical details on the cell improvement were disclosed.
Chinese manufacturer Longi holds the world record for perovskite-tandem solar cell efficiency, achieving 34.85% efficiency in April 2025. This cell device was developed in partnership with China’s Soochow University and was described in the paper “Efficient perovskite/silicon tandem with asymmetric self-assembly molecule,” which was recently published in nature.
