Global Busbar-free (0BB) Stringer Market Growth 2025-2031

The global Busbar-free (0BB) Stringer market size is predicted to grow from US$ 126 million in 2025 to US$ 304 million in 2031; it is expected to grow at a CAGR of 15.9% from 2025 to 2031.

Traditional solar cell modules contain a main grid and a secondary grid (fine grid) in the metal electrode part, where the main grid is used to collect and connect the secondary grid current in series, and the secondary grid is used to collect photogenerated carriers. 0BB technology eliminates the main grid and only retains the secondary grid, thereby reducing the use of metal electrodes, reducing the shading area, and improving the photoelectric conversion efficiency.

Driven by the cost reduction and efficiency increase in the photovoltaic industry, the 0BB process, which is regarded as the ultimate welding technology in the photovoltaic industry and has the dual advantages of saving silver paste costs and increasing component power, is being introduced into the market at an unprecedented speed. At present, the 0BB string welding process has become the focus of the next round of photovoltaic technology competition with its huge potential. From TOPCon to HJT, and then to the BC field, many industry leaders have deployed 0BB technology in order to gain the upper hand in this technological innovation. Although various companies are competing in the development and application of 0BB technology, and new products are emerging in an endless stream, the technology still faces many challenges, including the selection of welding technology routes, the guarantee of yield in large-scale mass production, the stable maintenance of welding consistency, and the improvement of detection efficiency. From the equipment level, the string welding scheme of 0BB components is subdivided into four categories according to the interconnection method between the welding ribbon and the battery cell: film coating, printing glue + curing, printing glue + welding, welding + glue application. Each scheme has different process layouts and equipment requirements in different battery technologies, which undoubtedly puts higher requirements on the innovation and customization capabilities of equipment manufacturers.
