Two milestones, one important trend

  • JinkoSolar achieved another research record for N type Topcon cells at 25.4%
  • More than 100MW N-type panels have been produced by JinkoSolar for the Australian market since 2019


SYDNEY, October 14, 2021 – JinkoSolar Holding Co., Ltd. (“JinkoSolar” or the “Company”) (NYSE: JKS), one of the largest and most innovative solar module manufacturers in the world, today announced that it has achieved a major technical breakthrough on its N-type monocrystalline silicon solar cell. JinkoSolar has set a new world record for the fourth time in a year with the maximum solar cell conversion efficiency of 25.4% for its large-size passivating contact solar cell. This result has been independently confirmed by Japan Electrical Safety and Environment Technology Laboratories (JET).

At the same time, JinkoSolar announced that they have produced 100MW of N-type for Australia Australia since 2019. The increasing sales and improving technology confirm a distinct trend towards N-type modules.  As a leading solar module manufacturer globally, JinkoSolar continues to provide the Australian & New Zealand market with high efficiency products centered on technological innovation to promote the development of the local solar industry. Panels from the Expert Series, such as the current 370 watt and 390 watt Tiger N panels, will be joined by larger output panels in 2022.

JinkoSolar was the first of the major global manufacturers to offer a full range of N-type modules to Australia in 2019. Apart from the technology leadership, JinkoSolar continues to optimize their manufacturing process to increase the efficiency as well as the energy yield. Steady increases in performance and JinkoSolar’s recent record high cell efficiency of 25.4% are key reasons N-type TopCon has become the leading next-generation mainstream option after the mono PERC era. Such panels also have lower freight costs per watt, as well as using less materials per watt, and as a result JinkoSolar expects a significant number of its customers to adopt N-type modules.

The key difference between N-type and its P-type predecessor is that it is immune to boron-oxygen defects, which leads to decreased efficiency and purity in P-type panels. Thus, N-type modules are more efficient in use of space, which is important as Australian systems are growing in total output power. When compared to P-type PERC process technology, N-type TOPCon promises to increase cell efficiency by up to 5-6%, and power generation by 3% or more. In addition, N-type cells are not affected by light-induced degradation (LID). This is a significant loss of electricity generating capacity in P-type modules due to LID, in the order of 2% (or even more) degradation for initial year of exposure to the sun and 0.45-0.50% annually for next 24 years, while n-type degradation is less than 1% for the first year and 0.4% for rest 29 years based on JinkoSolar’s 30-year performance warranty.
