Previous research has emphasized the role of iodide and silver oxidation, and the role of hole tunnelling from the electron-transport layer into the perovskite to enable the flow of current under reverse bias in causing degradation. Here we show that device architecture engineering has a significant impact on the reverse bias behaviour of perovskite solar cells. By implementing both a ~35-nm-thick conjugated polymer hole transport layer and a more electrochemically stable back electrode, we demonstrate average breakdown voltages exceeding −15 V, comparable to those of silicon cells. Our strategy for increasing the breakdown voltage reduces the number of bypass diodes needed to protect a solar module that is partially shaded, which has been proven to be an effective strategy for silicon solar panels. Perovskite solar cells degrade when subjected to reverse bias. Jiang et al. show that relatively thick hole transport layers and metal back contacts with improved electrochemical stability afford better tolerance to reverse bias.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141899746","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, non-precious metals used in AEMFCs to catalyse the hydrogen oxidation reaction are prone to self-oxidation, resulting in irreversible failure. Here we show a quantum well-like catalytic structure (QWCS), constructed by atomically confining Ni nanoparticles within a carbon-doped-MoOx/MoOx heterojunction (C-MoOx/MoOx) that can selectively transfer external electrons from the hydrogen oxidation reaction while remaining itself metallic. Electrons of Ni nanoparticles gain a barrier of 1.11 eV provided by the QWCS leading to Ni stability up to 1.2 V versus the reversible hydrogen electrode (VRHE) whereas electrons released from the hydrogen oxidation reaction easily cross the barrier by a gating operation of QWCS upon hydrogen adsorption. The QWCS-catalysed AEMFC achieved a high-power density of 486 mW mgNi−1 and withstood hydrogen starvation operations during shutdown–start cycles, whereas a counterpart AEMFC without QWCS failed in a single cycle. Non-precious metals used at the anode of anion-exchange-membrane fuel cells to catalyse hydrogen oxidation are prone to self-oxidation. Here Zhou and colleagues report that a quantum well-like catalytic structure containing Ni nanoparticles within a C-doped MoOx/MoOx heterojunction can mitigate such degradation by a gating operation.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41560-024-01604-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141895393","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}

Current cathodes fail to meet these requirements owing to structural and electrochemical strains at high voltages, leading to fast capacity fading. Here we present a cathode with a coherent architecture ranging from ordered to disordered frameworks with concentration gradient and controllable Ni oxidation activities, which can overcome voltage ceilings imposed by existing cathodes. This design enables simultaneous high-capacity and high-voltage operation at 4.5 V without capacity fading, and up to 4.7 V with negligible capacity decay. Multiscale diffraction and imaging techniques reveal the disordered surface is electrochemically and structurally indestructible, preventing surface parasitic reactions and phase transitions. Structural coherence from ordering to disordering limits lattice parameter changes, mitigating lattice strain and enhancing morphological integrity. The dual-gradient design also notably improves thermal stability, driving the advancement of high-performance cathode materials. Battery cathodes tend to degrade severely during high-voltage operations. Here the authors present a cathode design with a structurally coherent architecture, ranging from ordered to disordered frameworks, that addresses this issue.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141877737","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}

This transition, however, could strain electricity grids. Using a large-scale dataset with over 200 million global positioning system records from 20,992 buses in Beijing, we explore the technical, economic and environmental implications of transforming public transport depots into renewable energy hubs. Here we show that solar photovoltaic reduces the grid’s net charging load by 23% during electricity generation periods and lowers the net charging peak load by 8.6%. Integrating energy storage amplifies these reductions to 28% and 37.4%, respectively. Whereas unsubsidized solar photovoltaic yields profit 64% above costs, adding battery storage cuts profits to 31% despite offering grid benefits. Negative marginal abatement gains for CO2 emissions underscore the economic sustainability. Our findings provide a model for cities worldwide to accelerate their commitments towards sustainable transport and energy systems. Electric bus charging could strain electricity grids with intensive charging. Here the authors present a data-driven framework to transform bus depots into grid-friendly profitable energy hubs using solar photovoltaic and energy storage systems.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141877738","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 use a conjoint experiment to assess preferences for large-scale energy projects among residents and local elected officials in Pennsylvania—a key transition state with high solar potential where siting authority rests at the local level. We find that residents prefer solar to other energy projects, and job creation and cooperative community ownership are associated with increased support. Public and elected official support decreases when projects are owned by foreign companies. We find limited partisan differences in preferences, suggesting a path towards bipartisan support for such projects. Elected officials misperceive their constituents’ preferences, underestimating support for renewable energy and the importance of job creation. As local officials are key decision-makers regarding infrastructure development, their preferences and perceptions of constituents’ preferences may dictate which energy projects are approved and what community benefits they deliver. Pennsylvanians support energy infrastructure projects that use solar, create jobs and are community owned.
