A key challenge in optimizing thermoelectric performance lies in effectively reducing lattice thermal conductivity while simultaneously ensuring an uninterrupted pathway for charge carriers. While numerous extrinsic strategies have been proposed to control phonon dynamics, a critical and less-explored avenue lies in understanding the chemical bonding and structural features that underpin intrinsic mechanisms. Engineering ferroelectric instability in crystalline solids has emerged as an efficacious method to control structural disorder through local distortions involving the off-centering of cations. The coupling of soft phonons associated with these instabilities with acoustic phonons suppresses their ability to transport heat while preserving the anionic sublattice and global structural symmetry, which facilitates efficient electronic transport. In this perspective, we discuss the chemical design approaches to tune ferroelectric instability in a few group IV metal chalcogenides such as SnTe, GeSe, and GeTe for achieving high thermoelectric performance. We highlight the intriguing phenomenon of inhomogeneous ferroelectric instability recently demonstrated in doped GeTe to obtain fascinating glassy thermal transport. Finally, we provide an outlook on key experimental and theoretical challenges, potential new research directions, and the integration of advanced techniques aimed at ferroelectric instability-driven low thermal conductivity and high thermoelectric performance.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 8","pages":"3866–3875"},"PeriodicalIF":18.2,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144806688","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 can be attributed mostly to the short length of lab-scale measurements and the complexity of cell operation parameters. Here we introduce a high-throughput cell operation testing methodology, including data evaluation and process optimization by machine learning algorithms. An autonomously operating test station allowed collection of enough data to develop an artificial neural network model. When the model is trained on a fraction of a large data set, predictions for the operation of the same cell under different conditions are very precise. Accurate predictions can also be made for newly assembled cells and at parameter settings outside of the training parameter space. Our results pave the way for the long-term stable operation of CO2 electrolyzers by the adaptive optimization of the process conditions based on machine-learning-based holistic data evaluation.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 8","pages":"3845–3850"},"PeriodicalIF":18.2,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acsenergylett.5c01133","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144806412","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}

Here, we create a heterojunction by forming a CYS(PbBr2) perovskite layer over CsPbI3 using cysteamine (CYS: +NH3(CH2)2S–) and PbBr2, replacing fullerene derivatives and resulting in a shallower Fermi level. This heterojunction facilitates effective electron transfer and transport in the absence of fullerene derivatives and enables an enhancement of power conversion efficiency from 12.11 to 16.47% for inverted CsPbI3 perovskite solar cells. This intrinsic stable heterogeneous layer effectively stabilizes the CsPbI3 layer through a robust Pb–S bond, rendering PSCs retaining 63% of their initial efficiency after 600 h aging at 20% relative humidity.

In industry, catalysts invariably undergo deactivation, requiring frequent regeneration or replacement. Traditional methods for enhancing stability typically involve modifying the catalyst composition or structure and optimizing the reaction conditions. Plasmonic photocatalysis is emerging as a promising technology for efficient, environmentally friendly catalysis, frequently demonstrating improved performance due to nonequilibrium, “hot” carriers generated by plasmon decay. Here we demonstrate how hot carriers in plasmonic photocatalysis enhance the catalyst stability. Using copper-based antenna-reactor photocatalysts in three representative reactions (nitrous oxide decomposition, carbon monoxide oxidation, and steam methane reforming), we observe how hot carriers facilitate desorption of poisoning species, maintaining catalyst stability. Furthermore, plasmonic photocatalysis improves the structural stability by preventing catalyst sintering, which is a common phenomenon in thermocatalysis. Our findings highlight hot carrier generation as an effective strategy for stabilizing copper-based antenna-reactor photocatalysts, paving the way for extended catalyst lifetimes.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 8","pages":"3799–3807"},"PeriodicalIF":18.2,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144806123","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}

Compared to the widely used ZnO ETL, SnO2 offers improved optoelectronic properties and more favorable energy band alignment with PbS QDs. Despite these advantages, the application of SnO2 in PbS QD solar cells has been comparatively less explored. Herein, we report an interface engineering strategy to utilize SnO2 ETLs for efficient PbS QD photovoltaics. Our results show that devices employing bare SnO2 ETLs exhibit significantly lower performance compared to the ZnO-based counterparts. Interfacial analysis reveals that proton release from the SnO2 surface during PbS QD deposition leads to the detachment of QD ligands, resulting in the formation of oxidized Pb species. To address this issue, we introduced a surface passivation strategy to effectively suppress the SnO2-induced degradation reactions. Consequently, a power conversion efficiency of 12.7% was achieved, surpassing that of ZnO-based devices (10.4%).","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 8","pages":"3818–3826"},"PeriodicalIF":18.2,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144806439","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}

Additionally, we demonstrate that heat predominantly accumulates in the perovskite layer, inducing localized thermal stress, especially at pyramid valleys.
