- JinkoSolar achieves a certified conversion efficiency of 34.82% for its N type TOPCon perovskite tandem solar cell.
- New result surpasses the company’s previous world record of 34.76%.
- Breakthrough strengthens the commercialisation prospects of next generation perovskite tandem solar technology.
JinkoSolar has announced that its self-developed N type TOPCon perovskite tandem solar cell has achieved a conversion efficiency of 34.82%, according to certification by the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences.
The achievement exceeds the company’s previous record of 34.76% for a similar tandem cell architecture and marks the 33rd time that JinkoSolar has set a new world record for solar cell efficiency and module power output.
According to the company, the latest efficiency milestone was driven by innovations across several key technologies. These include a dual layer composite passivation contact structure for N type TOPCon cells, multidimensional interface passivation technology, gradient crystallisation kinetics control strategies, and enhanced optical coupling and light management technologies.
The result represents a significant step towards the large scale commercial deployment of perovskite tandem solar cells, a technology widely viewed as one of the most promising pathways for improving photovoltaic performance beyond the limits of conventional silicon based solar cells.
JinkoSolar, which was the first photovoltaic manufacturer to achieve large scale mass production of N type TOPCon technology, continues to invest in both TOPCon technology development and next generation perovskite tandem cell research.
The company said the new efficiency record further demonstrates the technical viability and industrialisation potential of combining TOPCon and perovskite technologies, supporting efforts to deliver higher efficiency solar modules for utility scale and commercial applications.
