Zhongbu Qingtian's self-developed high-speed BC string welding machine ignites SNEC Shanghai Photovoltaic ExhibitionIssuing time:2024-06-13 17:37  The 2024 SNEC Shanghai Photovoltaic Exhibition was grandly held on June 13th at the National Convention and Exhibition Center (Shanghai), with an unprecedented scale and the largest ever. As a platform based technology, BC technology became the "hot topic" of this exhibition.  Professor Martin Green, known as the "Father of Solar Energy in the World," once said in an interview, "The next five years will be an important period of technological competition, with intense competition between TOPCon and HIT. However, in the long run, BC may become the winner This is not only a recognition of BC battery technology, but also an expectation for the future. BC cell is a general term for various types of back contact structured crystalline silicon solar cells, mainly including IBC, HBC, TBC, HPBC, ABC and other cells.
 ● Leading both in technology and compatibility ● Accumulate steadily, with a promising future ahead BC technology is a platform based technology that can be combined with PERC, TOPCon, HJT and other processes to break through the efficiency bottleneck of a single technology route and achieve efficiency breakthroughs. BC batteries have excellent technical compatibility and are deterministic platform technologies that can be compatible with TOPCon process to form TBC technology, and can also be integrated with HJT technology to form HBC technology, continuously improving battery efficiency. Meanwhile, in order to achieve breakthroughs in conversion efficiency, technologies such as TOPCon and HJT must also be combined with the BC technology platform. TOPCon+BC?TBC HJT+BC?HBC
It is expected that by 2025, the market share of BC batteries will account for 10% -15%, with an average annual expansion scale of about 40GW. In the future, BC technology is expected to occupy 30% -40% of the market share, coexisting with TOPCon, HJT, PERC and other technologies to build a diversified battery market pattern.
In the past, BC batteries were limited by many pain points such as long production processes and some difficult processes, and have always been a "luxury" in the photovoltaic field, with a relatively small market share. However, the improvement of power generation efficiency has always been the first principle of the development of the photovoltaic industry. With the addition of industry giants such as Longi and Aixu, it confirms that BC technology has much greater potential for continuous efficiency improvement in the future than other technological routes, and will inevitably become the mainstream of the industry in the future. Based on the market demand for BC batteries, Zhongbu Qingtian New Energy has independently developed a series of advanced equipment such as high-speed BC string welding machine CTM-60BC and fully automatic double track string welding machine CTM-25BC, which greatly improves the production efficiency and reliability of BC batteries. This means that products with high difficulty technology and high cost in the past are beginning to move towards the era of affordable prices, promoting the mass production process of BC batteries.
