Here, we report a bottom-up crosslinking strategy utilizing 4-(aminomethyl)benzoic acid as a dual-anchor linker integrated into quasi-two-dimensional (2D) perovskite to reduce the weak van der Waals gap between individual 3D perovskite layers and to functionalize the NiOx/perovskite interface. This approach not only enhances the coupling of the perovskite slabs within the quasi-2D structure, leading to enhanced stability, but it also promotes the vertical growth of highly ordered, phase-pure low-dimensional perovskite films with improved carrier transport. The quasi-2D perovskite solar modules (PSMs) fabricated using this method have demonstrated an optimal efficiency of 16.05% over an aperture area of 9.66 cm2, utilizing a blade-coating technique in ambient air. Meanwhile, the PSMs have passed the standard damp-heat and operational stability tests for 1,000 h with negligible degradation, as verified by the VDE Prüfund Zertifizierungsinstitut GmbH (VDE Institute).","PeriodicalId":343,"journal":{"name":"Joule","volume":"77 1","pages":""},"PeriodicalIF":39.8,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804968","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}

Separation processes play a pivotal role in improving sustainability in fields such as industrial processes, resource recycling, wastewater treatment, and water desalination, among others. Electrochemical systems have gained increased attention as effective separation platforms, not only in performance but also as a potentially energy-efficient approach. However, the reliance on non-renewable energy sources, such as fossil fuels, for electricity generation limits the advancement toward a fully sustainable separation process. Integration of separation processes with eco-friendly renewable energy sources can increase overall sustainability and decrease carbon footprint. In this review, we provide an overview of electrochemical separations and recent efforts to integrate them with renewable energy sources such as heat and solar energy. We discuss electrochemical separations, including electrosorption and electrodialysis, and research to transition these processes to thermoelectrochemical (TEC) and photoelectrochemical (PEC) platforms. Finally, we discuss current challenges and future prospects in direct integration of renewable energy sources with separation processes.","PeriodicalId":343,"journal":{"name":"Joule","volume":"20 1","pages":""},"PeriodicalIF":39.8,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797676","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}

Active grid connection requests are more than double the total installed capacity of the US power plant fleet (2,600 vs. 1,280 GW). The time required to secure a connection has increased by 70% over the last decade, and withdrawal rates remain high at 80%, suggesting a constrained transmission system that jeopardizes energy transition targets.

Defining the electrolyte properties necessary to achieve ideal electrodeposition/stripping (E/S) thus remains elusive. Here, we reveal for the first time, rapid magnesium electrodeposition behavior that forms densely aligned, micron-sized thin platelets by establishing a dynamic bare magnesium/electrolyte interface during high-rate net plating. This effectively “SEI-free” interface allows facile magnesium diffusion and migration in stripping with near-unity E/S efficiency under demanding conditions over long-term cycling. The intrinsic electrolyte stability of the salt/solvent at the molecular level is the key to forming such an interface. The efficacy of the dynamic bare interface and an electrodeposited, free-standing magnesium anode is demonstrated in a high-areal-capacity full cell.

These facet variations manifest in differences in optoelectronic characteristics, including energy level alignment and carrier mobility. Heterojunction structures, a staple in traditional photovoltaic devices, involve the strategic combination of two distinct components with unique optoelectronic properties. The heterogeneity of optoelectronic properties across the facets offers opportunities to create junctions that can enhance device performance. Here, we engineer a bilayer facet heterojunction (FHJ) in a perovskite-based photovoltaic device through integrating two films expressing distinct crystal facets (001)/(111). The buried interface of the FHJ devices demonstrates effective type II band alignment. The FHJ has propelled the power conversion efficiency (PCE) of evaporated perovskite solar cells (PSCs) to 24.92%. The operational stability of the target device has been significantly improved by retaining 91.7% of its initial performance after 2,000 h of operation at maximum power output.","PeriodicalId":343,"journal":{"name":"Joule","volume":"21 1","pages":""},"PeriodicalIF":39.8,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142760634","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}

We highlight their strengths and weaknesses amidst the challenges of a changing grid. It is argued that FMs learning from diverse grid data and topologies, which we call grid foundation models (GridFMs), could unlock transformative capabilities, pioneering a new approach to leveraging AI to redefine how we manage complexity and uncertainty in the electric grid.
