At SNEC 2025, JinkoSolar showcased a wide range of its new offerings, including upgraded TOPCon PV modules . The company also promoted its technological progression in perovskite/TOPCon tandem solar cell development during the event.
At the company’s booth, the TaiyangNews team received a briefing on the showcased Tiger Neo 3.0 module from Andy You, Solution Engineer at JinkoSolar.
Tiger Neo 3.0 Module
The Tiger Neo 3.0 series 66QL6-BDV model on display, featuring 264 pieces of 1/4-cut G12R size cells, is rated for a power output and efficiency of 670 W and 24.8%, respectively. Additionally, it offers a bifaciality of up to 85%. Sized at 2,382 × 1,134 × 30 mm and laminated with 2 mm-thick front and rear glass, this 32.4 kg module is promoted for utility-scale, C&I rooftops, and distribution markets.
Leveraging the technological advancements of JinkoSolar’s patented n-type TOPCon cell technology, based on its HOT 4.0 technology platform, the company has developed an upgraded Tiger Neo 3.0 module, boasting higher power and efficiency compared to its predecessor. According to You, the cell boasts of multiple advanced features like 20BB, half-cut passivation (HCP), MAX, and FP technology, which contribute to higher efficiency.
The adoption of the 20BB metallization pattern outlines multiple optical and electrical performance enhancements compared to its SMBB counterpart. These are reduced current path lengths of each finger and the nearest busbar, which reduces series resistance and improves cell efficiency. Its finer fingers with narrow width facilitate less shadow on the cell surface, leading to higher light absorption and improved short-circuit current (Isc), compared to its counterpart. Due to its metallization architecture, the mechanical stress is evenly distributed along the cell edges, minimizing formation of microcracks. The half-cut passivation (HCP), where the edges of the non-destructive laser-based cut cells are passivated, prevents minority charge carrier recombination at the edges. This, in turn, enhances the electrical performance of the cell and improves cell stability.
In addition, the adoption of multi-piece (1/4th of a cell) cell-based module layout or Multipieces Tech (FP) increases module power by reducing internal current loss. This module layout, featuring a higher number of cells, also reduces the impact of partial shading on overall power generation vis-à-vis conventional half-cut cell-based modules. Its high bifaciality of up to 85% is attributable to the incorporation of MAX Tech. In this technology, localizing poly-Si/SiOx passivated contacts, rather than depositing a continuous poly-Si layer over an ultra-thin tunneling oxide (SiOx), helps minimize rear-side parasitic absorption and enhances bifaciality. The company offers the module with a product and performance warranty of 12 and 30 years, respectively. According to the company’s press release, this model is expected to be commercially available in Q4 2025.
