Shanghai-based solar module manufacturer JinkoSolar has achieved a groundbreaking milestone with its N-type TOPCon-based perovskite tandem solar panel, reaching a record conversion efficiency of 33.84%. Independently verified by the Shanghai Institute of Microsystem and Information Technology, this advancement surpasses the company’s previous record of 33.24% and marks JinkoSolar’s 27th world record for photovoltaic (PV) efficiency and power output.
The breakthrough is attributed to advancements in passivation technology, including full-area passivated contact, perovskite interfacial defect passivation, and bulk defect passivation. These innovations demonstrate the compatibility of TOPCon technology with next-generation perovskite/silicon tandem panels, offering a significant step forward for the solar industry.
Perovskite materials are celebrated for their high efficiency and low manufacturing costs, yet concerns over durability in harsh conditions remain a challenge for large-scale applications. Despite these hurdles, industry leaders predict that next-generation tandem solar panels could achieve conversion efficiencies exceeding 43% in the near future.
This achievement by JinkoSolar highlights ongoing advancements in PV technology, paving the way for a greener and more sustainable energy future. “Our commitment to innovation continues to push the boundaries of solar cell efficiency,” said Jin Hao, CTO of JinkoSolar.
The record comes as the race for solar efficiency intensifies, with Chinese manufacturer LONGi recently achieving a 34.6% efficiency milestone in September 2024, surpassing Saudi Arabia’s KAUST, which held the prior record of 33.7%. These developments underscore the rapid evolution of perovskite-based solar technologies and their potential to revolutionize renewable energy.
