Core Viewpoint - The establishment of the Global BC Ecological Collaborative Innovation Center in Jiaxing, Zhejiang Province, aims to accelerate the industrialization of BC technology, marking a significant milestone in the expansion of the BC ecosystem and collaborative innovation in the photovoltaic industry [2][3]. Group 1: BC Technology and Industry Development - BC technology is recognized as the ultimate technological route in the single crystal silicon era, playing an increasingly important role in the photovoltaic industry [3][6]. - The potential of BC technology can be fully realized through closer collaboration and joint innovation across the entire industry chain [3][9]. - The domestic annual production capacity of BC batteries is expected to reach 300 GW to 400 GW in the next three to five years, indicating over ten times the current production capacity [8]. Group 2: Collaborative Innovation and Ecosystem Building - The future of the photovoltaic industry relies on innovation and collaboration, as the transition from "cheap" to "indispensable" cannot be achieved by a single company [9][11]. - Longi Green Energy has initiated the construction of the BC ecosystem, focusing on open, collaborative, and win-win innovation with partners [11][12]. - As of May 2025, Longi has engaged with 191 global ecological partners, resulting in 55 collaborations and covering seven major fields, including silicon wafers, batteries, and hydrogen energy [14]. Group 3: Case Studies and Practical Applications - Collaborative projects have led to cost reduction and efficiency improvements, such as the partnership between Shenzhen Shijin Technology and Longi in graphite boat development [15]. - Baosteel and Longi are working together to replace aluminum frames with high-strength steel frames, contributing to a zero-carbon future [15]. - The collaboration with Hangzhou Fumo New Materials Technology has resulted in the development of BC component solutions suitable for various applications [15]. Group 4: Future Directions and Strategic Goals - The 2025 BC Ecological Innovation Summit emphasized the need for joint efforts from upstream and downstream enterprises to build the BC ecosystem [16]. - Longi is committed to investing more resources in collaborative innovation and ecosystem enhancement, ensuring that partners benefit from project revenues and intellectual property protection [18].
