钙钛矿GW级产能爆发，产业链上有哪些机会？

Core Viewpoint - The year 2025 marks the beginning of large-scale production for perovskite solar cells, with significant capacity expansion expected in the coming years, driven by advancements in technology and production efficiency [1][8][10]. Industry Overview - The perovskite solar cell industry is transitioning from a phase of "excess capacity" to one of "incremental explosion driven by technological iteration" [1]. - Major players in the industry include equipment leaders with full-line delivery capabilities, core material suppliers, and component manufacturers with advantages in tandem technology [1]. Technological Advancements - Laboratory efficiency for single-junction perovskite cells has reached 27.3%, while tandem cells have surpassed 35.0%, significantly exceeding the theoretical limit of 27.9% for silicon cells [2][5]. - Stability issues, previously a major concern, have been addressed, with companies like GCL-Poly achieving certification for durability under extreme conditions [6]. Production Capacity and Timeline - The production capacity for perovskite solar cells is set to explode, with global capacity expected to exceed 5 GW by 2027 and surpass 30 GW by 2030 [1][10]. - Key milestones include the launch of several GW-scale production lines by leading companies such as JinkoSolar and GCL-Poly in 2025 and 2026 [9][10]. Cost Structure and Economic Viability - Current production costs for perovskite modules are approximately 1.2 yuan/W, but are projected to decrease to 1.0 yuan/W by 2026, approaching the cost levels of silicon cells [1][20]. - The cost structure indicates that material costs account for over 76% of the total, suggesting rapid cost reduction potential as domestic production of materials increases [19]. Equipment and Material Localization - All core equipment for perovskite production has achieved 100% localization, eliminating reliance on foreign technology [13]. - Significant progress has been made in the localization of key materials, with companies like Jinjing Technology achieving over 95% localization for TCO conductive glass [15].
