ABU DHABI, UAE, April 29, 2024 /PRNewswire/ -- Huasun Energy, the world's largest manufacturer of heterojunction (HJT) products, has unveiled its latest innovation in high-efficiency modules, featuring innovative zero-busbar technology (0BB). This cutting-edge advancement has been seamlessly integrated into Huasun's mass production lines, including the Himalaya G12 series and the Everest G12R rectangular series of large-format modules. Leveraging innovative improvements in printing processes, front layer soldering, thin solar ribbons, ultra-thin silicon wafers, and encapsulation and sealing techniques, Huasun has significantly raised the electrical, optical, and temperature coefficient performance of HJT modules, improving the market competitiveness of its product line.
While 0BB technology is moving toward industrialization, there are variations among companies regarding specific implementation methods. Huasun's approach primarily involves welding and dispensing, incorporating advantages such as stronger adhesion, improved hot spot resistance, and removal of carrier film.
Specifically, regarding the manufacturing process of 0BB cells, Huasun adopts simpler two-step screen printing (SP) technology to deliver superior product quality and improved electrical and cell-to-module (CTM) performance, which which demonstrates significant advantages over multiple super busbars. (SMBB) in terms of open circuit voltage (OCV), conversion efficiency and power output of the module.
"Huasun's 0BB modules employ front layer soldering, which offers benefits including reliable soldering, reduced contact resistance, improved hot spot resistance, lower hot spot temperature, and higher module reliability. Additionally, the design reduces coverage metal on the back, expanding the light-receiving area and achieving bifaciality of up to 90%," added Christian Comes, BD director of Huasun in Europe.
0BB technology supports the trend toward thinner silicon wafers by providing greater reliability without a main grid, thinner strips, minimal stress and lower fragmentation rates. By leveraging Downshift Light Conversion (DS) encapsulation and PIB edge sealing technology, Huasun's HJT 0BB modules offer a substantial increase in power generation capacity. This advancement translates into more reliable products for owners of utility, commercial and industrial rooftop PV projects (C
The successful mass production of HJT products "G12 0BB" and "G12 R 0BB" marks another milestone for Huasun in its quest to improve efficiency. Committed to advancing the industrialization of HJT technology, Huasun continues to promote the widespread adoption of 0BB high-efficiency modules, providing next-generation heterojunction products with higher conversion efficiency, higher reliability and lower levelized cost of electricity (LCOE). for photovoltaic projects around the world.
