Groundbreaking Advances in Solar Technology
JinkoSolar, a leading Chinese solar module manufacturer, has announced an impressive achievement in solar technology: a stunning power conversion efficiency of 33.84% for its perovskite-silicon tandem solar cell utilizing n-type wafers. This achievement marks a significant leap from their previous record of 33.24%.
This advancement has been confirmed by the Shanghai Institute of Microsystem and Information Technology, part of the prestigious Chinese Academy of Sciences (CAS). The design integrates JinkoSolar’s cutting-edge N-type high-efficiency monocrystalline TOPCon solar cell as its base, benefiting from several technological enhancements.
These innovations include full-area passivated contact technology and specialized methods for reducing interfacial and bulk defects. These advancements combine to significantly elevate the efficiency of the perovskite/TOPCon tandem cell.
Despite JinkoSolar’s success, the global record for perovskite-tandem solar cell efficiency is held by Longi, which achieved 34.6% in September 2024. In the competitive landscape of solar research, Saudi Arabia’s King Abdullah University of Science and Technology previously reported a 33.7% efficiency for a similar design.
Experts from Germany’s Fraunhofer Institute for Solar Energy Systems suggest that, with architectural changes, such as the replacement of traditional materials in the cell structure, the theoretical efficiency of these cells could reach as high as 39.5%. This paves the way for further exploration in the solar energy sector.
