Global MBB Round Ribbon Market Strategic Research Report

Scope of the Report

The global MBB Round Ribbon market size is predicted to grow from US$ 313 million in 2025 to US$ 460 million in 2032; it is expected to grow at a CAGR of 5.9% from 2026 to 2032.

MBB Round Ribbon serves as a core conductive material in the manufacturing of photovoltaic modules. It refers to a tin-coated copper strip with a circular cross-section, specifically designed for the series or parallel interconnection of solar cells, where it functions to collect and conduct electric current.

The upstream supply chain for MBB round solder ribbon primarily involves oxygen-free copper rods and various solder metals—such as tin, lead, silver, and bismuth. Key critical factors in this process include the purity of the copper substrate, consistency of wire diameter, coating thickness, solder wettability, low yield strength, and surface cleanliness. Downstream, the product is primarily supplied to photovoltaic module manufacturers, where it is utilized for the string soldering and current collection of crystalline silicon cell modules—including types such as TOPCon, PERC, HJT, and BC. Its value proposition centers on reducing shading losses and series resistance, minimizing silver paste consumption, boosting module power output, and enhancing the solar cells' tolerance to micro-cracks.

In 2025, global sales volume for MBB round solder ribbon is projected to reach approximately 40,000 tons, with an average ex-factory price of around $8,000 per ton; the gross profit margins for major industry manufacturers are expected to range between 5% and 10%.

Industry growth for MBB round ribbons is primarily driven by the demand for higher-power photovoltaic modules and cost reduction. Technologies such as multi-busbar (MBB), super multi-busbar, and busbar-less designs are driving the transition of interconnection materials from traditional flat ribbons to round ribbons characterized by finer diameters, lower yield strength, and higher consistency. This transition is facilitated by the fact that these advanced technologies shorten current transmission paths, reduce series resistance, minimize the consumption of front-side silver paste, and lower shading losses. Furthermore, the round cross-section enhances the internal reflection and recapture of incident light, making it particularly well-suited for high-efficiency cell architectures such as TOPCon, HJT, and BC. Concurrently, solder ribbon manufacturers remain significantly susceptible to price fluctuations in key metals—including copper, tin, silver, and bismuth—while also facing relatively lengthy cycles for customer certification and product adoption. Looking ahead, MBB round solder ribbons are expected to remain one of the dominant interconnection materials for mainstream crystalline silicon modules.
