As the world’s first PV module manufacturer to realize mass production of ZBB-TOPCon PV modules, Astronergy continues to lead in both product standardization and innovation, setting industry benchmarks and accelerating the technological progress in the PV industry.
Through continuous breakthroughs in materials and design, Astronergy’s ZBB-TOPCon PV modules are produced to meet the evolving demands of global energy markets while maximizing efficiency and sustainability.
High-Efficiency TOPCon 5.0 Solar Cell Technology
Powered by various industry-leading technologies, the newly upgraded TOPCon 5.0 solar cell technology significantly improves the cells’ Open-circuit Voltage (Voc) and Isc, and fill factor, reduces parasitic absorption, enhances passivation effect and light capture capability, thus increasing the cell efficiency up to over 27%.
Innovative Cell Screen Design
Astronergy’s ZBB-TOPCon PV modules feature advanced cell screen designs that offer multiple advantages and aesthetic benefits.
- PAD-point-free and harpoon-free structure: With no PAD points and harpoon-like ribbons on the cells, combined with more numerous ribbons, the light-exposed area of the cells is greatly increased, enhancing the modules’ aesthetic appearance and conversion efficiency as a result.
- Optimized contact structure: It realizes the contact optimization between fingers and ribbons, to improve the weld tensile strength and the current collection capacity of cell edges. This structure can also achieve a better bonding effect between ribbons and fingers after the lamination process, all contributing to higher product reliability.
Industry-Leading Integrated Film Technology
Astronergy adopts a low-fluidity carrier film to pre-fix metal ribbons on the surface of the solar cell, and the soldering alloying occurs in the lamination process. Besides, the temperature of the manufacturing process is lower than 150℃, resulting in no high-temperature welding stress, lower energy consumption, and lower carbon emissions. Without flux usage, there are no Volatile Organic Compounds (VOCs) emissions, ensuring both eco-friendliness and cost-efficiency.
Moreover, Astronergy also integrates novel technologies and materials, such as low-temperature/low-lead ribbons, high aesthetic glass, rectangular wafers, low-fluidity adhesive films and carrier films and all-black aesthetic cells, to deliver a complete ZBB-TOPCon product portfolio. This lineup includes large-size modules for utility-scale projects and small-size modules for distributed projects, offering diverse solutions for global clients.
