JinkoSolar, the global leading PV and ESS supplier, recently announced that its self-developed N-type TOPCon perovskite tandem cell has achieved an efficiency of 34.82%, as certified by the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences. This breakthrough surpasses the company’s previous record of 34.76% for similar tandem cells, marking the 33rd time JinkoSolar has broken world records in cell efficiency and module power.

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. This milestone marks a critical step forward in the industrialization of next-generation perovskite tandem technology.

As the world’s first PV company to achieve large-scale mass production of N-type TOPCon technology, JinkoSolar continues to deepen its expertise in TOPCon technology iteration and cutting-edge perovskite tandem technology. This efficiency breakthrough further validates the feasibility and industrialization prospects of TOPCon and perovskite tandem technologies.
