Risen Energy(SZ:300118)2025-12-28 12:44Group 1: Technology Overview - The earliest satellites used p-type crystalline silicon photovoltaic cells, which had a conversion efficiency of less than 10%. Currently, gallium arsenide photovoltaic cells have achieved efficiencies above 30% but are limited by high costs and complex production processes [2][3]. - Recent advancements in rocket reusability and satellite design have reduced launch costs, making space infrastructure projects more feasible [2][3]. Group 2: Product Advantages - The company's p-type ultra-thin heterojunction (HJT) products offer advantages in terms of production cost, specific power, and adaptability to flexible solar wings, making them suitable for space applications [3][4]. - Compared to mainstream PERC cells, the HJT cells have a thinner profile (50-70μm) and better radiation resistance, which is crucial for low Earth orbit satellites [4][5]. Group 3: Market and Production Capacity - The company has a history of shipping several thousand p-type ultra-thin HJT cells over the past three years, with customers primarily located in Europe and North America [5][6]. - Future production capacity will be adjusted based on order volume and pricing, with plans to expand pilot production lines or adapt mass production lines as needed [6]. Group 4: Technological Development - The company is focusing on enhancing its heterojunction technology while also developing tandem solar cell technology, achieving a conversion efficiency of 30.99% for perovskite/silicon tandem solar cells [6]. - Collaboration with leading perovskite companies is underway to advance the next generation of high-efficiency solar cell technology [6]. Group 5: Financial Outlook - The special business segment of p-type ultra-thin heterojunction cells shows significant growth potential, although it currently represents a small portion of the company's revenue [6].
