Insights

Solar Technology Expert

The breakthrough in perovskite tandem solar cell technology achieving 33.84% efficiency represents a quantum leap in photovoltaic performance. The key innovation lies in the synergistic combination of N-type TOPCon technology with perovskite, creating a dual-layer system that captures a broader spectrum of light. The 0.6% improvement from their previous record may seem incremental, but in the highly competitive solar industry, such gains are revolutionary.

The implementation of full-area passivated contact technology significantly reduces electron recombination losses, while the perovskite interfacial defect passivation addresses one of the major challenges in perovskite commercialization - stability and durability. This advancement positions JinkoSolar at the forefront of next-generation solar technology, potentially enabling more efficient and cost-effective solar panels in the future.

For context, traditional silicon solar cells typically max out at around 26-27% efficiency due to the Shockley-Queisser limit. Breaking through this barrier with tandem technology opens new possibilities for solar energy economics, potentially reducing the physical footprint needed for solar installations by up to 25% while maintaining the same power output.

Market Research Analyst

This technological breakthrough could significantly strengthen JinkoSolar's market position in the highly competitive solar manufacturing sector. While commercial implementation may still be years away, this advancement demonstrates JinkoSolar's R&D capabilities and could lead to valuable intellectual property rights. The company's consistent track record of setting efficiency records (now 27 times) suggests a strong innovation pipeline that could translate into future market share gains.

The timing is particularly strategic as global solar installations are projected to accelerate, driven by climate policies and improving economics. Higher-efficiency panels command premium pricing, potentially improving profit margins in an industry often challenged by commoditization. Investors should note that while perovskite technology shows immense promise, successful mass production and long-term stability remain key challenges that will need to be addressed before commercial deployment.

SHANGRAO, China, Jan. 6, 2025 /PRNewswire/ -- JinkoSolar Holding Co., Ltd. (the "Company," or "JinkoSolar") (NYSE: JKS), one of the largest and most innovative solar module manufacturers in the world, today announced that it has achieved a significant breakthrough in the development of its N-type TOPCon-based perovskite tandem solar cell. Independently tested by the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, the cell achieved an impressive conversion efficiency of 33.84%, surpassing JinkoSolar's previous record of 33.24%. This achievement marks the 27^th time JinkoSolar has set a world record for efficiency and power output for PV products.

The record-breaking perovskite tandem solar cell utilizes JinkoSolar's N-type high-efficiency monocrystalline TOPCon solar cell as the bottom cell, enhanced by significant advancements across multiple key technologies.
