Here, two A-DA’D-A type acceptors, PEH-F and TEH-F, are designed and synthesized with different conjugated outer side chains, to pursue high-efficiency and cost-effective OSCs for industrialization. In comparison with TEH-F (thienyl outer side chain), PEH-F with phenyl outer side chains delivers up-shifted frontier energy levels, wider optical bandgap, and higher absorption coefficient. By adopting low-cost polymer PTQ11 as donor, the PEH-F-based device realizes low energy loss of 0.511 eV with suppressed non-radiative loss of only 0.182 eV, and exhibits efficient exciton dissociation and hole transfer even at an extremely small highest occupied molecular orbital offset of 0.06 eV. Eventually, the PTQ11:PEH-F-based binary device demonstrates a superior PCE of 19.73 % with high Voc and Jsc simultaneously, which is the highest PCE to date for OSCs based on low-cost polymer donors. More importantly, this device shows small efficiency-cost gap for industrialization with the estimated minimum sustainable price (MSP) of 0.35 $ Wp-1, which is dramatically lower than other reported high-performance OSCs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"75 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637819","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 efficiencies of all-PSCs remains lower than those of small molecule acceptor (SMA)-based OSCs due to their unfavorable active-layer morphology. The complicated molecular interaction and aggregation behavior involved in all-polymer blends make it highly challenging to achieve optimal morphology. Herein, two volatile solid additives named dibenzothiophene (DBTP) and 4-bromodibenzothiophene (4-BDBTP) were developed to finely modulate the morphology of all-PSCs. We clarify that the subtle bromine substitution enables 4-BDBTP to form enhanced intermolecular interactions with the host material, which is beneficial to controlling the molecular aggregation and crystallization, thus facilitating the formation of more ordered molecular stacking and well-defined fibril networks in the all-polymer blend. As a result, the 4-BDBTP-treated-PM6:PY-DT all-PSC achieved a high efficiency of 19.30% (certified as 18.82%). Moreover, two other all-polymer systems validate the broad applicability of 4-BDBTP, and these devices all showed enhanced efficiencies. Our work demonstrates the promising role of solid additive on regulating molecular aggregation and packing in all-polymer blends, offering valuable insight into fabricating high-performance all-PSCs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"10 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637852","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}

Specifically, they can impart materials with unique structures and customized properties, thereby showcasing new attributes and application potential. In this review, we describe the various influences that the high-entropy concept exert on electrochemical performance of materials. We begin by introducing the concept and the basic effects, namely structural stabilization, lattice distortion, high defect density, and cocktail effects. Then, we provide a comprehensive overview of the fundamental advantages of high entropy or compositional/occupational disorder in battery materials design, including anodes, cathodes, and electrolytes. The summary of these effects is crucial for understanding how entropy affects the electrochemical properties of materials (redox activity, cyclability, etc.). Additionally, we outline the challenges encountered in this area of research and discuss the critical factors for rationally designing novel electrode materials, as well as the potential future directions for high-entropy strategies in the field of electrochemical energy storage.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"7 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637821","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}

The primary challenge of mitigating zinc dendrite formation in these batteries is addressed through electrolyte strategies, focusing on reducing water activities. Despite advancements in extending cycle life, a trade-off emerges between enhanced cycling performances and increased polarization, impacting energy efficiency. This often-overlooked concern becomes crucial when considering the payback period in energy storage systems. Experimental data illustrate the intricate relationship among electrolyte modifications, polarization, cycle life, and energy efficiency. The economic implications are scrutinized, emphasizing the need for a balanced approach in the electrolyte development to optimize service life without compromising energy efficiency. Striking this balance is imperative for the economic viability and environmental efficacy of AZIBs in sustainable energy storage solutions.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"66 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637822","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}

Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is a widely adopted hole transport material, particularly for perovskite solar cells (PSCs). However, Improving the performance and stability of PEDOT:PSS based perovskite optoelectronics remains a key challenge. We show that amine-containing organic cations de-dope PEDOT:PSS, causing performance loss, which is partially recovered with thiocyanate additives. However, this comes at the expense of device stability due to cyanogen formation from thiocyanate-iodine interaction which is accelerated in the presence of moisture. To mitigate this degradation pathway, we incorporate an iodine reductant in lead-tin PSCs. The resulting devices show an improved power conversion efficiency of 23.2% which is among the highest reported for lead-tin PSCs, and ~66% enhancement for the TS80 lifetime under maximum power point tracking in ambient conditions. These findings offer insights for designing next-generation hole extraction materials for more efficient and stable PSCs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"17 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637823","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}

To facilitate the integration of knowledge generated from these studies into formulating next-generation precision care for survivors of childhood cancer, we summarize key findings of genetic and epigenetic association studies of long-term therapy-related adverse effects including subsequent neoplasms and cardiomyopathies among others. We also discuss therapy-related genotoxicities including clonal haematopoiesis and DNA methylation, which may underlie accelerated molecular ageing. Finally, we highlight enhanced risk prediction models for survivors of childhood cancer that incorporate both genetic factors and treatment exposures, aiming to achieve enhanced accuracy in predicting risks for this population. These new insights will hopefully inspire future studies that harness both expanding omics resources and evolving data science methodology to accelerate the translation of precision medicine for survivors of childhood cancer.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"5 1","pages":""},"PeriodicalIF":78.5,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594783","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}
