JinkoSolar Achieves 33.24% Efficiency on Tandem Solar Cell

• JinkoSolar sets new efficiency record with 33.24% on n-type TOPCon-based perovskite tandem solar cell, showcasing commitment to innovation in sustainable energy.

JinkoSolar has achieved a conversion efficiency of 33.24% on its n-type TOPCon-based perovskite tandem solar cell, as confirmed by the Shanghai Institute of Microsystem and Information Technology. The tandem solar cell utilized Jinko's high-efficiency monocrystalline TOPCon solar cell as the bottom cell, with various materials and technology innovations contributing to the record-breaking efficiency.

The breakthrough demonstrates the compatibility of TOPCon as a mainstream solar cell technology with next-generation perovskite/silicon tandem cell technology, surpassing the efficiency limit of single-junction silicon solar cells. JinkoSolar's CTO, Dr. Jin Hao, emphasized the company's commitment to technological innovation and its contribution to a greener and more sustainable energy structure. In comparison, LONGi achieved 33.9% efficiency with its own silicon-perovskite tandem solar cell design in November 2023, although it was not TOPCon-specific.
