Maxwell showcased its latest product, a high-efficiency cell manufacturing solution based on GW-level bifacial microcrystalline heterojunction (HJT), at booth A560 in Venue NH, attracting enthusiastic attention and exchanges from both Chinese and foreign customers, as well as various partners.
Achieve Cost Reduction and Efficiency Improvement with HJT
In 2022, Maxwell successfully developed its high-efficiency cell technology based on bifacial microcrystalline HJT and pioneered whole-line mass production equipment, with a single-line annual production capacity of 600MW. Thanks to the company's leading and boosting efforts, bifacial microcrystalline technology emerged as the mainstream in the field of HJT in 2023, achieving a significant improvement in the conversion efficiency of HJT cells during mass production.
Through further research and innovation, the company upgraded the annual single-line throughput of the bifacial microcrystalline HJT cell manufacturing solution to GW level in early 2024. The core PECVD and PVD equipment have their chambers expanded while maintaining the original multi-chamber structure design, thus preserving the legacy of layered high-quality coating. This not only ensures the high efficiency and high pass-yield of cells but also significantly improves whole-line production capacity and reduces operating costs in various aspects such as unit labor, unit equipment occupation, and unit energy consumption.
Recently, whole-line production witnessed the first solar cell produced by a global-leading solar cell and module enterprise. With the expansion of mass production, whole-line production is expected to see higher efficiency, capacity, and pass yield. Furthermore, it is anticipated to become the most cutting-edge and advanced HJT production line in the industry.
In addition, Maxwell has introduced its second-generation HJT None Busbar (NBB) technology and module stringer equipment. Centered on customer requirements, Maxwell has accelerated the industrialization process of HJT and the development of cost reduction and efficiency improvement in the solar industry by overcoming challenges in mass production from the perspective of cell and module manufacturing.
As the "carbon peak and carbon neutrality" strategy is promoted worldwide, solar power will play an increasingly important role as a clean, safe, and economically beneficial renewable energy source in energy transformation. The solar industry will experience an urgent demand for advanced technology and new productivity. As a pioneer in the field of HJT, Maxwell will continue to explore, innovate, and optimize equipment and technological solutions, assisting the industry in achieving upgrades and iterations and embracing a carbon-free future.
