In recent years, as the cost of silicon material has neared rock bottom and the iteration of N-type technology has driven an increase in silver paste usage, "silver reduction" has increasingly become the main focus for "enhancing efficiency and reducing costs" within the photovoltaic industry. Amongst these initiatives, the 0BB (no busbar) technology has emerged as a leader due to its significant benefits, such as reduced silver paste consumption, ultra-thin battery thickness, increased module power, and compatibility with various N-type cell processes like TOPCon/HJT. However, due to technological bottlenecks, the market has aspired long for a successful and stable 0BB stringer for mass production.
As a pioneer in the domestication of photovoltaic equipment, LEAD possesses deep insights into industry challenges and has overcome significant technological bottlenecks. In 2022, the company led the industry by introducing the "mass-production 0BB stringer," utilizing a unique process to comprehensively support cost reduction and efficiency gains in the photovoltaic sector.
Entering 2024, as N-type cells begin mass production on a large scale, the 0BB string welding process emerges as a new-generation platform technology that enhances cost-effectiveness and efficiency. The demand for equipment is set to expand even further. In response, LEAD focuses on industry innovation and accelerates technological iteration, launching an innovative 0BB stringer that boasts "high precision, high reliability, and low cost." Integrating the features of conventional SMBB string welders and tile-stacking technologies, LEAD paves the way for a new era of cost reduction and efficiency in the photovoltaic "N-age."
