Accordingly, we developed an antisolvent-seeding strategy that decouples self-assembly monolayers (SAMs) adsorption from dissolution, while integrating perovskite seeding. A high-polarity solvent prevents SAMs clustering during dissolution, while a low-polarity antisolvent promotes high-density SAMs formation during adsorption. Additionally, a pre-mixed seed layer further improves perovskite wettability, crystallinity and adhesion. These advancements enable the fabrication of a 1.09-cm<sup>2</sup> flexible monolithic perovskite/CIGS tandem with a stabilized efficiency of 24.6% (certified 23.8%), comparable to the best-performing rigid perovskite/CIGS tandems and representing one of the highest efficiencies among flexible thin-film solar cells.

Hydrogen networks serve regions with high energy demand, whereas emissions are transported away in carbon dioxide networks. For the synthesis of carbonaceous fuels, it is less clear which input should be transported: hydrogen to carbon point sources or carbon to low-cost hydrogen. Here we explore both networks’ potential synergies and competition in cost-optimal carbon-neutral European energy systems. In direct comparison, a hydrogen network is more cost effective than a carbon network, as it serves to transport hydrogen to demand and to point sources of carbon for utilization. However, in hybrid scenarios where both networks are present, the carbon network effectively complements the hydrogen network, promoting carbon capture from distributed biomass and reducing reliance on direct air capture. The layouts of the hydrogen and carbon dioxide networks are robust if the climate target is tightened to be net negative.</p>","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"22 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819174","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, the device power conversion efficiency has remained stagnant for years. Deep-level defects, such as sulfur vacancies (V<sub>S</sub>), cause serious non-radiative recombination of charge carriers. Here we propose a passivation strategy for V<sub>S</sub> through the heat treatment of the CdS/CZTS heterojunction in an oxygen-rich environment. In this process, V<sub>S</sub> are occupied by oxygen atoms, suppressing V<sub>S</sub> defects. In addition, the diffusion of Cd ions to the CZTS absorber layer, and the formation of positive Na–O and Sn–O complexes can passivate related defects. These effects led to a reduced charge recombination and favourable band alignment. We demonstrate a certified efficiency of 11.51% for air-solution-processed CZTS solar cells (bandgap of 1.5 eV) without any extrinsic cation alloying.

Modifications at the surface of electrodes have been employed to accelerate HER, but effective guiding principles are lacking. Here we establish a molecular design strategy to enhance HER activity in alkaline media by up to 50 times by introducing an organic overlayer on Pt electrodes. We find that enhancement of HER activity by organic adsorbates is correlated with their binding energies to Pt electrodes; binding energy could be tuned by changing the number of aromatic rings and hydrophilicity of the adsorbates. Density functional theory calculations suggest that the overlayer led to a decrease in the <i>d</i>-band centre, resulting in weakened H adsorption, which mitigated its overbinding on Pt.

Quantifying this impact on wind energy potential is required for effective energy planning. However, complex turbine sound modelling combined with evolving policies have contributed to limited understanding of these policies’ impact on national wind technical potential. Here we develop an approach to evaluate wind turbine sound profiles across the United States and calculate setback distances from residential structures to translate sound-related policies into spatial turbine siting criteria. Compared to a baseline scenario that ignores sound, we find an 8% reduction in wind energy capacity when accounting for existing sound ordinances. Further, extrapolating a 45-A-weighted decibel (dBA) limit nationwide shows a 29% decline, disproportionately taken from high-quality and low-cost wind capacity. This reveals sound ordinances as a major factor in determining wind technical potential that could challenge US decarbonization goals reliant on wind energy.</p>","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"217 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143798276","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}
