Here we report on recent work to understand interrelationships between the intrinsic activity of Ni- and Pt-based electrolyzer cathode catalysts and their performance in zero-gap alkaline water electrolyzer assemblies. Our results suggest that nanoparticulate Ni–Mo exhibits HER activity that is roughly 10-fold lower than Pt–Ru on the basis of turnover frequency under low (≤100 mV) polarization conditions. We further found that the HER activity of Ni–Mo/C cathodes is inhibited by aryl piperidinium anion-exchange ionomers bearing bicarbonate counter-anions. After addressing this poisoning effect, we produced electrolyzer assemblies based on Ni–Mo/C cathodes that delivered indistinguishable current density vs cell potential relationships compared to otherwise identical assemblies with Pt–Ru cathodes. This result indicates that the contribution of the cathode to the total cell polarization is small, even for the less active Ni–Mo/C catalyst, and further implies that Pt-based cathodes can indeed be replaced by nonprecious alternatives with no loss in performance.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"95 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640187","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}

By integrating tailored passivation through a bifunctional molecule, we significantly improved both the optoelectronic properties and the colloidal stability of the QD inks. Consequently, the photovoltaic devices attained a power conversion efficiency (PCE) of 12.07%, marking the highest reported value among all PbSe QD solar cells. Additionally, the QD inks exhibit colloidal stability for over two months, demonstrating outstanding long-term performance.

Here, macroscopic charge transport is correlated with local lithium (Li)-ion diffusivity in HSEs, using poly(ethylene oxide) (PEO) as matrix and Li6PS5Cl as filler. Solvent- and dry-processing methods were evaluated for their morphological impact on Li-ion transport. Through multiscale solid-state nuclear magnetic resonance analysis, we reveal that the filler enhances local Li-ion diffusivity within the slow polymer segmental dynamics. Phase transitions indicate inhibited crystallization in HSEs, with reduced Li-ion diffusion barriers attributed to enhanced segmental motion and conductive polymer conformations. Relaxometry measurements identify a mobile component unique to the hybrid system at low temperatures, indicating Li-ion transport along polymer–filler interfaces. Comparative analysis shows solvent-processed HSEs exhibit better morphological uniformity and enhanced compatibility with Li-metal anodes via an inorganic-rich solid electrolyte interphase.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 4","pages":"1762–1771 1762–1771"},"PeriodicalIF":19.3,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsenergylett.5c00214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818921","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}

In the present study, we develop a machine learning (ML) approach that accurately predicts the current–voltage behavior of 3D/2D-structured (FAMA)Pb(IBr)3/OABr HOIP solar cells under AM1.5 illumination. Using measured responses from 368 devices, we train a neural network (NN) with three optical inputs of constituent HOIP films (transmission, spectrally resolved photoluminescence, and time-resolved photoluminescence) to predict the solar cell’s open-circuit voltage (Voc), short-circuit current (Jsc), and fill factors (FF). The model achieves 91%, 94%, and 89% accuracy for 95% of Voc, Jsc, and FF predictions, with coefficient of determination (R2) values of 0.47, 0.77, and 0.58, respectively. By linking ML predictions to extracted physical parameters from the measured HOIP films optical properties, we identify key factors influencing the prediction results. Furthermore, we develop separate ML-classification algorithms that identify degraded solar cells with >90% accuracies using the same optical data. This work demonstrates an efficient, nondestructive approach for HOIP solar cell assessment that can assist in accelerating the next generation of perovskite solar cell developments.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"17 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635388","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}
