Published in Nature, this study addresses durability challenges in inorganic perovskites. The international team led by South China University aims for efficiencies above 30%. This technology could surpass limitations of conventional silicon-based panels, offering higher performance potential under various conditions. ## Corrected Error The original publication contained an error in Extended Data Fig. 4b regarding tin (Sn) data curves. Beyond 357.99 seconds, data was accidentally overlapped with Extended Data Fig. 4c during transcription. Nature has implemented corrections in HTML and PDF versions. Supplementary materials allow comparison with original data. Such corrections maintain scientific integrity while improving research accuracy. ## Research Collaboration The study involved researchers from South China University, Chinese University of Hong Kong, Germany's Friedrich-Alexander University, and Sweden's Linköping University. Supported by Chinese Academy of Sciences and Beijing's National Center for Nanoscience, the multidisciplinary team combines expertise in materials science and photovoltaics. International cooperation accelerates innovation in renewable energy technologies. ## Correction Process Scientific journals like Nature maintain rigorous post-publication correction protocols. 'Author Correction' notices preserve research transparency without invalidating original findings. The corrected version retains the original DOI while addressing identified issues. This process demonstrates the self-correcting nature of scientific inquiry and commitment to accuracy in academic publishing. ## Technical Challenges Inorganic perovskite tandem cells face stability and scalability hurdles crucial for commercialization. Interface issues between layers remain a primary research focus. This study specifically targets material durability under high temperature and humidity conditions. Long-term performance data is essential for industry adoption. Researchers are developing novel encapsulation techniques to extend operational lifetimes. ## Industry Impact Perovskite photovoltaics could revolutionize solar energy markets with potential cost reductions. Commercial production is anticipated by 2026, particularly for rooftop and building-integrated applications. Higher efficiencies may accelerate global energy transition timelines. The technology's lightweight nature enables new deployment scenarios impossible with conventional panels, expanding renewable energy access. ## Global Cooperation This research exemplifies growing international collaboration in renewable energy R&D. Combining resources from China, Germany, and Sweden accelerates problem-solving for complex material challenges. Shared knowledge networks become increasingly vital for photovoltaics advancement. Cross-border partnerships help overcome technical barriers through complementary expertise and infrastructure. ## Future Outlook Perovskite tandem technology may redefine solar energy's future with its efficiency potential and flexible applications. This correction reinforces the study's methodological rigor. As energy transition accelerates, scientific precision must match technological innovation. The research represents significant progress toward sustainable energy solutions, balancing performance with durability for practical implementation. ## Sources covering this story - https://www.nature.com/articles/s41586-026-10984-9 — --- _Summary written by Brifing from the original reporting.
