观察当前中国发展,"稳定"和"创新"是两个关键词。在变革时代,稳定对世界至关重要;没有创新,人 类就无法应对所面临的挑战。 广东深圳的快速发展,就得益于这两方面的成功实践,也是中国转型发展成果累累的一个例证。深圳曾 是一个不起眼的渔村,如今已发展成为拥有近1800万人口的大都市,汇聚了华为、腾讯、比亚迪、大疆 等科技企业。每次到访深圳,我都能切身感受到这座城市在绿色创新方面取得的进步。今年4月重访深 圳,"深圳奇迹"再度令我深受震撼。深圳不仅实现了经济快速增长,更展现出卓越的环保意识:全市所 有公交车和出租车均为电动汽车,城市中心拥有广阔的绿色走廊和湿地,为迁徙候鸟提供了重要栖息 地。 一段时间以来,个别国家宣布退出气候变化《巴黎协定》和世界卫生组织,不断挑起关税争端,这些做 法使世界陷入巨大的不确定性中。中国的稳定发展与此形成鲜明对比。中国2025年经济增长预期目标在 5%左右,将继续成为拉动全球经济增长的重要引擎。中国还制定了一整套应对气候变化的方案,二氧 化碳排放力争在2030年前达到峰值,努力争取2060年前实现碳中和。中国在气候行动中积极承担大国责 任,处于全球绿色科技价值链的领先地位,为全球绿色转 ...

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].
