As a technical leader in the PV industry, JinkoSolar, with its strong innovation and R&D capabilities, has set multiple world records in key tandem solar cell technologies. Its perovskite/TOPCon tandem solar cell, based on N-type TOPCon, has achieved a conversion efficiency of 34.22% certified by a third party, breaking the world record for the 28th time. This milestone highlights JinkoSolar’s continuous leadership in next-generation high-efficiency PV technology R&D.
670W Ultra-High Power: Tiger Neo 3.0 Modules Reach Unprecedented Performance Levels
At the SNEC exhibition, JinkoSolar unveiled its Tiger Neo 3.0 series of solar modules, which incorporate multiple innovative technologies including 20BB, HCP, MAX, and FP. These technologies effectively reduce optical and electrical losses, significantly improving the battery's conversion efficiency, enhancing the module's power output, and ultimately achieving an impressive performance with a power output of up to 670W, a module efficiency of 24.8%, and a bifacial ratio of 85%. The high efficiency not only increases power generation but also continuously reduces the levelized cost of electricity (LCOE), providing photovoltaic projects with greater investment returns. With its high bifacial power gain and low levelized cost of electricity (LCOE), the Tiger Neo 3.0 module has become an outstanding high-performance product.
Additionally, the product has undergone comprehensive upgrades in printing technology, module welding, and Bus-barless Cell design, enhancing structural strength, reducing the risk of microcracks and high-temperature hotspots, and further improving product stability and lifespan. This makes the product suitable for various application scenarios, including utility scale power plants, commercial and industrial rooftops, and distribution markets, meeting the needs of different users. It is reported that the Tiger Neo 3.0 module product is expected to begin accepting orders in Q4 2025.
