Here we demonstrate that interfacial electric field discontinuity caused by the dielectric constant mismatch between the perovskite and C60 layer triggers abrupt voltage breakdown and accelerates instability. This dielectric mismatch drives carrier tunnelling and interface reactions under reverse bias. To mitigate these effects, we have introduced graded dielectric layers that smooth the electric field profile, correct abnormal band bending to reduce tunnelling current and inhibit halide ion accumulation. The tandem devices achieve efficiencies of 34.18% (certified: 33.76%) and 34.03% for silicon heterojunction and tunnel oxide passivated contact architectures, respectively, and retain over 92% of their initial efficiency after 1,000 h at −15 V. A large-area multicell string reaches 31.00% efficiency and maintains over 90% of the initial value after 1,000 h of shading stress. This work advances the development of perovskite/silicon tandem solar cells under real-world conditions. Perovskite/silicon tandem solar cells degrade under reverse bias.

However, we find that this strategy alone cannot meet future material demand. If announced projects materialize, domestic production can meet 2035 demand for raw lithium, lithium carbonate, lithium hydroxide, electrolytes and separators used in major battery chemistries. However, many other materials still face substantial and persistent gaps even with demand-side strategies, including improved material efficiency, enhanced battery recycling and battery chemistry shifts. Shortfalls of ~30–70% persist for upstream cobalt, graphite, nickel and their midstream refined materials. For some of these materials, gaps may widen because ~30–100% of projected domestic supplies rely on early-stage projects, which may not advance. Downstream, cathode and anode active materials face ~15–75% shortfalls. Therefore, securing US battery materials will require investment across the domestic supply chain, reductions and shifts in material demand and international sourcing. As the USA works to secure supplies of electric vehicle battery materials, Lu et al. show that this will require investment across the domestic supply chain, demand-side strategies and continued international sourcing.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 7","pages":"1019-1031"},"PeriodicalIF":70.1,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148522940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hybrid perovskite/organic architectures that incorporate organic semiconductor layers offer a promising solution to improve moisture resistance while enhancing near-infrared photon harvesting. However, direct integration often causes energy-level misalignment and charge accumulation, limiting efficiency and stability. Here we investigate charge accumulation mechanisms and engineer the electronic structure of these hybrid solar cells using multiphysics modelling. We present a cascade hole-transfer strategy that employs an electron-donating polymer with a deep highest-occupied molecular orbital, which suppresses charge recombination in the perovskite bulk and at interfaces. Solar cells achieve a power conversion efficiency of 27.18% (certified 26.71%) and maintain 95% of their initial efficiency after 3,000 h under damp-heat conditions (ISOS D-3 protocol, 85 °C, 85% RH).

Past research has proposed numerous variables as potential key predictors of support for mitigation policies but has failed to comprehensively evaluate and compare their predictive importance and identify the strongest predictors within specific mitigation domains. We used machine-learning models to identify the strongest predictors of energy policy support in informed citizens, validate these results by forecasting the outcome of a real-world referendum on renewable energy in Switzerland and test their generalizability to public support for other climate mitigation measures across six European countries. We identified affective responses, societal and environmental policy-impact beliefs, fairness perceptions and perceived trends in policy support over time as the strongest predictors of energy policy support. Using these predictors, we achieved high accuracy in predicting support for a real-world referendum as well as support for different climate mitigation measures across Europe. New research finds that across Europe, peoples’ perceptions of the societal and environmental impact and the distributional fairness of an energy policy, together with the emotions experienced towards the policy, are strongly related to policy support.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 7","pages":"1055-1066"},"PeriodicalIF":70.1,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148522941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we identify that the Na+ coordination environment critically influences the Na-site accessibility and redox activity in Na4Fe3(PO4)2P2O7-type cathodes. Combined experimental and theoretical analyses reveal that precise V3+ substitution at the Fe2 site harmonizes Na+ coordination geometry and softens the polyanionic framework, thereby activating previously inert Na sites and stabilizing high-voltage redox reactions above 4 V. The optimized Na3.4Fe2.4V0.6(PO4)2P2O7 achieves full Na+ utilization (3.4 Na+, 150.7 mAh g−1) and a 52% increase in energy density (487 Wh kg−1), approaching the practical limit of Li-ion phosphate cathodes. It also demonstrates exceptional durability over 10,000 cycles in the 2.1-4.5 V range and stable pouch-cell performance. These findings provide a coordination-based strategy to overcome intrinsic capacity limitations in phosphate cathodes, enabling high-energy, durable Na-ion batteries. Fe-based polyanionic cathodes are promising for Na-ion batteries but are limited by inactive Na sites and irreversible Na loss. Here the authors employ targeted V3+ substitution to tune the Na+ coordination environment, activate inert sites and stabilize high-voltage redox for high-performance Na-ion batteries.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 6","pages":"915-925"},"PeriodicalIF":70.1,"publicationDate":"2026-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147966992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
