Astronergy Pioneering in ZBB-TOPCon Technology with Large-Size Module Products

On September 18 th , Astronergy announced the successful roll-out of ASTRO N 78- cell ZBB-TOPCon PV modules from Astronergy Fuyang Manufacturing Base, marking the official mass production of Astronergy’s large-size ZBB-TOPCon PV module series.

In November 2023, Astronergy first introduced ASTRO N 54-cell ZBB-TF TOPCon PV modules globally. In the same year, Astronergy proudly became the first manufacturer in the PV industry to be awarded the ZBB-TOPCon product certificate at the mass-produced level by TÜV Rheinland. The expansion of ZBB large-size products, including ASTRO N 72-cell and ASTRO N 78 cell ZBB-TOPCon PV modules, was officially announced during SENC 2024 in Shanghai.

ZBB（Zero BusBar）technology utilizes more and thinner ribbons to replace traditional cell busbars. This design increases the light absorption area of the cell and reduces the risk of hidden cracks, enhancing current collection and improving the reliability of current transmission. Meanwhile, Astronergy’s innovative carrier film has been developed with high bonding adhesion to realize the tight connection between ribbons and cells. Furthermore, the low-temperature manufacturing process effectively reduces internal stresses and provides better performance in terms of mechanical properties, thermal reliability and PID resistance.

In addition, the manufacturing process produces no flux or VOCs emissions, making the PV modules more environmentally friendly. By leveraging ZBB technology, Astronergy removes pad points and harpoon-like grid lines, resulting in a more visually appealing design.

Transitioning from small-size to large-size ZBB-TOPCon PV modules demonstrates Astronergy’s dedication to technological innovation, which will greatly enhance the adaptability of its products to meet the diverse needs of global clients.

Recently, ASTRO N 78-cell ZBB-TOPCon PV modules have passed rigorous hot- spot endurance tests conducted by TÜV Rheinland and TÜV NORD, following the IEC 63126:2020 standard. This showcases the exceptional reliability and performance of ZBB-TOPCon technology and Astronergy’s module products.

With ZBB-TOPCon module capacity planned for over 6 GW in 2024, Astronergy is ready to meet the growing demands of the solar market and keeps supplying module products with high efficiency and quality guarantee.
