Longi(SH:601012) 3 6 Ke·2025-09-02 07:20Core Viewpoint - The article highlights the significant impact of Lanzhou University and its alumni on the global photovoltaic (PV) industry, particularly through the success of Longi Green Energy, which has become a leader in the solar energy sector over the past decades [4][5][20]. Group 1: Longi Green Energy's Achievements - Longi Green Energy, founded by three alumni from Lanzhou University, has achieved the highest cumulative shipment of monocrystalline silicon wafers globally over the past decade and has consistently ranked among the top two in module shipments for the last six years [4][5]. - The company has set world records for silicon cell conversion efficiency, reaching 27.3% in May 2024, and has broken a 36-year monopoly on efficiency records held by overseas brands [11][20]. Group 2: China's Dominance in the PV Industry - China dominates the global PV industry, with over 90% market share in polysilicon, silicon wafers, solar cells, and modules [5][20]. - In 2024, China produced 839 TWh of solar energy, leading the world in solar power generation [6]. Group 3: Technological Innovations and Strategic Choices - Longi's decision to pursue monocrystalline technology over the more common multicrystalline route was pivotal, as it allowed the company to maintain a cost advantage in electricity generation despite the higher initial investment [11][20]. - The shift in focus to monocrystalline technology occurred during a period of rising prices for multicrystalline materials, which ultimately benefited Longi as competitors struggled [11][20]. Group 4: Lanzhou University's Role - Lanzhou University has produced numerous influential figures in the PV industry, contributing to its reputation as a breeding ground for talent in this sector [12][20]. - The university's strategic focus on physics, chemistry, and materials science has fostered a strong foundation for its alumni to excel in the PV field [17][20]. Group 5: Future Innovations and Sustainability - Lanzhou University is actively involved in developing new technologies, such as a hybrid photovoltaic-thermal power generation system and innovative methods for hydrogen production, which aim to enhance energy efficiency and sustainability [21][23]. - The university's research teams are also exploring ecological restoration methods in conjunction with PV installations, promoting both energy generation and environmental conservation [24][26].
