Core Viewpoint - The research conducted by the team from Nanjing University of Aeronautics and Astronautics addresses the long-term stability challenges of perovskite solar cells in outdoor environments, achieving comparable performance to commercial silicon solar cells [1][2]. Group 1: Research Findings - The study published in Science on May 29, 2025, introduced a vapor-assisted surface reconstruction technique that mitigates irreversible degradation in industrial-scale perovskite solar modules [1]. - The developed perovskite solar module, with an area of approximately 0.8 square meters, achieved a power conversion efficiency of about 19.6%, maintaining this output after 45 days of outdoor operation in summer [1]. - The research team effectively isolated surface defects using vapor deposition techniques, which reduced ion migration and surface ion defect concentration, thus controlling the dynamics of ion migration during light-dark cycles [1]. Group 2: Performance Metrics - The industrial-scale perovskite solar module, measuring 785 square centimeters, maintained over 97% of its initial efficiency after 101 light-dark cycles at 50 degrees Celsius, demonstrating excellent stability [1]. - The stability performance of the perovskite solar module in harsh summer conditions was comparable to that of the control silicon battery group [1]. Group 3: Technological Advancements - The two studies form a technological closed loop, systematically addressing the stability challenges across the entire chain from laboratory to production line to outdoor application, with related technologies already patented [2].
