Here we present a comprehensive nationwide assessment of over 500,000 US households, evaluating economic and back-up viability of solar–battery systems. We find that 60% of households could reduce electricity costs with average savings of 15%, whereas 63% of households could achieve affordable back-up power during power outages covering an average of 51% of their essential energy needs. However, these benefits show limited alignment with areas of greatest need, particularly in regions facing high outage risks. We also identify notable disparities in access to solar and battery, with less-populated and disadvantaged communities showing consistently lower viability. These findings demonstrate the need for targeted policy interventions to ensure equitable access to solar–battery benefits, especially as states transition from net energy metering to other electricity tariff policies. Rooftop solar and battery storage can reduce energy costs and provide affordable back-up power for over 60% of US households, but benefits often bypass the high outage risk and disadvantaged communities most in need.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 8","pages":"1025-1040"},"PeriodicalIF":60.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144756497","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}

However, their formation is hindered by the low reactivity of their bulky cations and solubility constraints of their precursors in orthogonal solvents compatible with underlying perovskites. Here we introduce a selective templating growth strategy that leverages conventional metastable LD interfaces as templates to drive the growth of more stable CI LD interfaces through an organic cation exchange process. Our prototype PSCs achieve efficiencies of 25.1% over an active area of 1.235 cm2—among the highest reported for 1-cm2 PSCs. The PSCs retain over 93% and 98% of their initial efficiency after 1,000 h of operation and 1,100 h of thermal ageing at 85 °C, respectively. The versatility of this strategy unlocks access to CI LD interfaces, paving the way for the development of more efficient and stable PSCs. Low-dimensional perovskites afford high efficiencies in solar cells but at the expense of stability. Rao et al. develop a template growth approach to form low-dimensional perovskites from low-reactivity and hence more stable organic cations.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 8","pages":"991-1000"},"PeriodicalIF":60.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144756496","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}

However, they are primarily confined to 2D design and fabrication technologies. Planar SOC stacks require complex multi-material components, leading to reduced compactness and high specific weight. Here we escape the 2D paradigm and adopt a true 3D design based on triply periodic minimal surface structures, enabling superior performance on gravimetric and volumetric bases. Leveraging the resolution and accuracy of additive manufacturing, we demonstrate a monolithic, gyroidal SOC that eliminates the need for metallic interconnects and sealing components. The monolith achieves optimal spatial utilization, exceptional mass-specific indexes, a straightforward manufacturing procedure and high electrochemical and thermomechanical stability. The specific power and volumetric power density surpass 1 W g−1 and 3 W cm−3 in fuel cell mode, and the mass-index and volume-index hydrogen production rates are about 7 × 10−4 Nm3 h−1 g−1 and 2 × 10−3 Nm3 h−1 cm−3 in electrolysis mode, nearly an order of magnitude enhancement compared to planar stacks. Solid oxide cells for interconversion of hydrogen and electricity typically have planar designs with low performance per unit mass and volume.

However, conventional spacer cations fail to exchange with the tightly bonded Cs cation in the inorganic perovskite to form 2D layers atop; or, when they do enable formation of a 2D layer, they migrate under heat, degrading device performance. Here we investigate the mechanisms behind 2D/3D heterostructure formation and stabilization. We find that 2D/3D heterostructure formation is driven by interactions between ammonium groups and [PbI6]4− octahedra. We thus incorporate electron-withdrawing fluorine to enhance inorganic–organic cation interdiffusion and promote heterostructure formation. We note that stability relies on interactions between the entire spacer cations and [PbI6]4− octahedra. We therefore introduce anchoring groups that double cation desorption energies, preventing cation migration at elevated temperatures. CsPbI3/(perfluoro-1,4-phenylene)dimethanammonium lead iodide heterostructures enable an efficiency of 21.6% and a maximum power point operating stability at 85 °C of 950 h. We demonstrate 16-cm2 modules with an efficiency of 19.8%. The formation of 2D perovskites in inorganic perovskite solar cells is hindered by the strong binding affinity of caesium ions.

Cobalt-based materials might address this requirement, but little is known about the mechanism of operation of these OER catalysts at low pH. Here we investigate the nature and evolution of the active cobalt sites along with charge- and mass-transfer processes that support their catalytic function within a cobalt–iron–lead oxide material using in situ spectroscopic, gravimetric and electrochemical techniques. We demonstrate that corrosion of the cobalt sites and their reformation through electrooxidation of dissolved Co2+ do not affect the catalytic mechanism and are decoupled from the OER. The OER-coupled charge transfer is supported by Co(3+δ)+-oxo-species, which are structurally different from those reported for alkaline/near-neutral conditions and are formed on a relatively slow timescale of minutes. These mechanistic insights might assist in developing genuinely practical catalysts for this vital technology. Cobalt–iron–lead oxide electrocatalysts show promise for the low-pH oxygen evolution reaction—an essential reaction in proton-exchange water electrolysis—but can suffer from corrosion. This study uncovers that the mechanism of cobalt site corrosion is decoupled from the oxygen evolution reaction, paving the way for more stable catalyst designs.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 8","pages":"1013-1024"},"PeriodicalIF":60.1,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41560-025-01812-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144639939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
