Summary of Conference Call on BC Technology and Solar Industry Industry Overview - The discussion centers around the BC (Bifacial Cell) technology in the solar photovoltaic (PV) industry, highlighting its potential to meet electricity demands at a lower cost while ensuring higher efficiency and reliability [1][2]. Core Insights and Arguments - BC Technology Advantages: - BC technology is essential for enhancing efficiency in crystalline silicon technology, with various passivation techniques requiring BC structures to achieve higher efficiency [1]. - The cost trend indicates that while previous manufacturing processes were costly, BC technology is now seen as the best route for crystalline silicon, with companies like Longi and Aiko having started R&D on BC cells since 2017, leading to a clear industrialization path for cost reduction [1]. - Efficiency and Cost Improvements: - Longi has developed an advanced version of BC technology (HPBC 2.0) that boasts a 5% efficiency advantage over TOPCon technology, with potential for a 10% increase in the next generation [2]. - Aiko plans to launch components with 25% efficiency within 1-2 years, aiming for 26% efficiency shortly thereafter [3][4]. - Market Differentiation: - Longi has successfully introduced ground-mounted products that leverage BC technology, which were previously thought to be limited to rooftop applications, thus enhancing their market value [5]. - Aiko emphasizes the safety of BC components, which reduce fire risks and ensure long-term reliability, contributing to their commercial value [6]. Market Share Projections - Longi predicts that BC technology will capture over 50% market share by 2027-2028, while Aiko notes that the lack of new investments in TOPCon capacity will shift resources towards BC technology [7]. - The anticipated efficiency for BC technology is projected to reach 27.5-28%, compared to TOPCon's 25.3%, with a gradual improvement expected over the next five years [7]. Collaborative Ecosystem Development - Aiko advocates for a collaborative approach within the solar industry, emphasizing the need for shared development based on patents to foster innovation and resource investment [7]. - Longi has engaged in various ecosystem initiatives, including joint projects with upstream and downstream partners to meet customer needs and enhance the overall supply chain [7]. Future of Zero-Carbon Energy - The discussion highlights the role of solar energy as a cornerstone for achieving a zero-carbon society, with Longi outlining a multi-step approach to transition towards renewable energy sources and energy storage solutions [8]. - Aiko envisions a prosperous ecological civilization where solar energy becomes the primary source of low-cost energy, addressing the current oversupply in the solar industry while meeting growing energy demands [8].
