First, we assess the impact on EY of degradation in the individual solar cell parameters of the perovskite top cell. Our analysis reveals that degradation in fill factor, due to a decline in perovskite top cell shunt resistance (RSh), has the most severe impact on the EY, emphasizing the imperative to rectify perovskite imperfections in thin film processing causing RSh decline. Second, we investigate implications of degradation in the perovskite top cell on the EY of current mismatched tandem solar cells. Third, we examine critical thresholds for the “acceptable degradation levels” in the perovskite top cell with regard to degradation in each solar cell parameter, assuming that the total loss in EY must be comparable to the degradation in state-of-the-art silicon. Overall, our study highlights that degradation of the perovskite top cell needs to be assessed with care when extrapolating the impact on the lifetime EY of perovskite-silicon tandem solar cells. The severity of degradation for different degradation mechanisms in a single junction perovskite solar cell cannot be translated one-to-one to tandem devices.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"12 11","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ente.202400998","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142195766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the phenomenon of capacity regeneration and the lack of confidence interval expression result in imprecise predictions. To tackle these challenges, this article proposes a novel method for predicting RUL by optimizing health features (HFs) and integrating multiple models. First, multiple HFs are collected from the charging curves, and the fusion HF is optimized by kernel principal component analysis. To eliminate local fluctuations caused by capacity regeneration effects, the complete ensemble empirical mode decomposition with adaptive noise is employed to decompose the fusion HF. Second, to address the issue of lacking confidence interval expression, a hybrid model is proposed by integrating bidirectional long short-term memory neural network with Gaussian process regression for effectively capturing the lithium-ion battery capacity-declining trend and accurately predicting the RUL. Finally, the proposed model's effectiveness is validated by comparing it with several other models using National Aeronautics and Space Administration and Center for Advanced Life Cycle Engineering datasets. The results indicate that this model achieves a root mean square error of 0.0023 and a mean absolute error of 0.0058, demonstrating significant improvements in predictive accuracy for RUL with high reliability.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"12 11","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142195701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, a flexible organic solar cell (OSC) with the PS‐G interfacial layer between the photoactive material and the Al metal has enhanced charge extraction mobility with a power conversion efficiency (PCE) of 3.5%. A new range of possibilities in metal:semiconductor:carbon:metal contact and interfacial tuning in OSCs are made possible by the fact that pure PS‐G without Al can successfully extract electrons with a PCE of 0.89%. Second, when used as the cathode in an Al–carbon battery, PS‐G demonstrates a specific capacity of 148 mAh g−1 at 50 mA g−1. At different current densities, PS‐G cathodes demonstrate high cycling stability (with 65% capacity retention over 100 cycles). Finally, the best of the fabricated OSCs and the Al–carbon batteries are then combined with a piezoresistive sensor that includes an active PS‐G electrode.

In this study, a novel KAl(SO4)2·12H2O/expanded graphite (EG) shape-stabilized composite phase-change material (PCM), with a melting temperature of 91.6 °C, latent heat of 245.7 kJ kg−1, and high heat conductivity of 2.07 W m−1 K−1, is prepared to manufacture a PCM-based module for space heating. This phase-change electric heating module is developed, and its heat storage and release characteristics are investigated through experimental and numerical studies. The numerical model is validated by experimental results. In view of the numerical simulation, the structure of the module is optimized and its thermal performance is studied. Based on the optimized module, a peak-valley time-of-use (TOU) electric heating module is finally proposed. It is revealed that the module exhibits good thermal performance and is capable of satisfying the indoor heating demand. The effective heat storage and release duration is 8.12 and 15.34 h, which can perfectly realize the operating mode under the “peak-valley TOU electricity” mechanism. In this study, it is demonstrated that peak–valley electric energy storage heating devices have broad prospects in building space heating and provides reference for future application.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"12 11","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142195707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, more research attention has been focused on viable catalyst synthesis processes including design, choice of precursors, reaction conditions, and regulation steps for achieving desirable properties and performances. Intriguingly, biomass has been demonstrated as a promising precursor for the potential design of different carbon-based catalysts for electrocatalytic oxidation/reduction reactions. In this review, the recent developments in using biomass precursors to derive different nanostructures are systematically discussed. The biomass-derived catalysts especially applied for reduction reactions (hydrogen evolution and oxygen reduction reactions) are summarized, and the impact of various catalysts’ engineering routes (incorporation of metals and nonmetals into the carbon structures) on the resulting structure–performance relationship is critically discussed. Further, this review highlights the performance of various biomass-derived catalysts toward electrocatalytic reduction reactions that unveil the catalyst's intrinsic features such as selectivity, activity, and durability. The summarized results and the critical discussion will facilitate screening of the best biomass precursor, identifying suitable regulation strategies for accomplishing desirable properties, and thus advancing the next-generation catalysts’ developments.
