Here, a transparent flexible electrode based on an embedded zinc grid with ≈1 µm linewidth is reported and its utility as a drop-in replacement for indium-tin oxide coated glass electrodes in model organic photovoltaic devices is demonstrated. The zinc grids are fabricated using the unconventional approach of condensation coefficient modulation, using a micro-contact printed patterned layer of poly(perfluorooctylmethylmethacrylate) to resist zinc condensation in the gaps between grid lines, together with a copper acetylacetonate seed layer to nucleate zinc condensation where grid lines are required. Density functional theory calculations of the strength of the interaction between zinc atoms and this fluorinated polymer provide fundamental insight into why the latter is so effective at resisting zinc condensation. The resulting zinc grid is embedded in a flexible polymer support and transferred to a flexible plastic substrate by delamination, which enables recovery and reuse of the fluorinated polymer.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"21 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987124","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, they cannot be directly exploited in conventional thermoelectric generators (TEGs) since ions cannot transport across the electrodes into the external circuit, and they cannot be used to harvest heat under steady temperature gradient. Here, a mixed ion/electron thermoelectric generator (MTEG) is reported that can continuously generate electricity under not only temperature fluctuation but also steady temperature gradient. It is consisted of a layer of an ionogel added with reduced graphene oxide (rGO). The ionic liquid is an ionic conductor, while rGO is an electronic conductor. The MTEG can supply a constant output voltage to the external load under steady temperature gradient, and the behavior is similar to that of the conventional TEGs, particularly when the external resistance is relatively high. The thermopower can be more than 7.0 mV K−1, higher than the Seebeck coefficient of the best electronic TE materials by 1–2 orders in magnitude. The operation mechanism is attributed to the hole tunneling across the rGO sheets and the high thermopower due to the Soret effect of the ions.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"5 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987126","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}

A key feature of IS-OPVs is the potential for increased power output as the photoactive area expands during stretching. However, current mechanical performance and stability still fall short of meeting the demands for practical applications. To overcome this limitation, the study introduces, for the first time, a polymer:gel blend system as a highly stretchable electron transporting layer (ETL), which significantly enhances both the power output and mechanical stability of IS-OPVs. This novel ETL plays a pivotal role in dissipating mechanical stress and protecting the brittle underlying layers. By incorporating this stretchable ETL, the device stretchability is reinforced by introducing the stretchable ETL, thereby maintaining the initial power conversion efficiency under 20% strain. As a result, the maximum power output substantially increases by 23%, from 0.28 to 0.35 mW, under large strain, while devices with conventionally brittle ETLs caused a 33% reduction in power output. This study thus offers a pathway toward durable and efficient stretchable photovoltaics.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"54 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987129","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}

Organic thermoelectric generators (TEGs) that promise to harness heat sustainably and cost-effectively are seen as pivotal elements in shaping future sensor infrastructures. Recent strides in morphological control through the alignment of conjugated polymer backbones have enhanced the thermoelectric performance of doped organic semiconductors to record values, matching expectations for real applications. However, the hurdles in crafting and deploying organic TEGs effectively exploiting aligned polymer films remain unexplored. This work presents a design and fabrication method to incorporate aligned films into a thin label-like TEG. Thin films of regioregular poly(3-hexylthiophene) (P3HT) and poly(2,5-bis((7-butoxyheptyl)thiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT-8O) are aligned via high-temperature rubbing technique inducing a high degree of anisotropy in their charge transport properties. The crystal structure and anisotropy of the films are exploited to realize monolithic TEGs by patterning conductive thermoelements via local inkjet doping of films transferred on ultrathin parylene substrates. The TEGs based on aligned P3HT and PBTTT-8O exhibit exceptional TEG power factors of 0.33 and 1.04 nW cm−2 K−2, respectively. Lastly, as a proof-of-concept use case for the TEGs, a thermoelectrically-powered volume-indicating label is presented as a potential application in the healthcare and food industries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"94 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987218","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 degradation mechanism has primarily been attributed to the oxidative instability of highly delithiated cathodes at high voltages (>4.3 V vs Li/Li+). However, the battery degradation also occurs under seemingly stable voltage ranges, the origin of which remains unclear. Herein, a hidden mechanism to induce surface reconstruction and oxygen loss is proposed, termed the “quasi-conversion reaction”, which is revealed to occur during electrochemical reduction (discharge) processes just below 3.0 V (vs Li/Li+). Combined experiments and first-principles calculations unveil that the oxygens at the surface can be extracted from the cathode lattice by forming lithium oxides and oxygen vacancies, at significantly higher potentials than conventional conversion reaction, due to the instability of surface oxygens coordinated with fewer cations than in the bulk. The chemical incompatibility between lithium oxides and commercial carbonate-based electrolytes results in electrolyte decomposition, forming an organic-rich blocking layer and gaseous byproducts, which further increases the cell impedance. This study emphasizes the necessity of a thorough understanding of surface instability upon reduction to develop long-lasting batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"10 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987219","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}

Two approaches that can be used to delaminate graphite are using ultrasonication (USD) and simple water delamination (WD). X-ray micro-computed tomography is used to characterize the graphite particles and show that particle fracturing is evident with both methods, but key structural metrics such as particle radius and diffusivity varied significantly. It is shown that blending 20% recovers material with 80% pristine graphite causes no statistically significant difference in the performance of the cells. This suggests that recycling anode materials can be achieved without significant post-processing required. For WD anode material, the spherical graphite particles are maintained, whereas USD significantly changes the morphology and produces a large amount of “needle-like” particles. Using 100% reclaimed anode material causes the performance of the cell to decrease to 279 mAh g−1 for WD material and 254 mAh g−1 for USD graphite.

Chemical doping with a single element often can optimize one of the parameters yet may deteriorate others, restricting the upper limit of ZT achievable. Multi-element doping can address this interdependence, allowing for simultaneous optimization of electrical and thermal properties. However, a clear selection rule for multiple dopants remains unclear. Here, a stepwise strategy is shown to improve the thermoelectric performance of metavalently bonded GeTe by enhancing density-of-states effective mass, increasing carrier mobility, and reducing thermal conductivity. These effects are realized by continuously introducing band convergence, lattice plainification, and structural defects. Specifically, band convergence is achieved by Cd doping to reduce the energy offset between light and heavy bands. The lattice plainification is enabled by filling Ge vacancies with Cu, which improves carrier mobility. Lastly, the lattice thermal conductivity is reduced via increasing phonon scattering by point defects caused by Pb doping and nanoprecipitates associated with all these dopants. Consequently, a peak ZT of 2.2 at 773 K and an average ZTave of 1.27 within 300–773 K are realized in Ge0.86Pb0.1Cd0.04Te-2%Cu2Te.

Here, five different lead-halide perovskite compositions are systematically examined to determine their temperature-dependent mobility, and the prevalent scattering mechanisms involved are identified. Dynamic disorder is proposed to be the predominant scattering mechanism at room temperature and above, as evidenced by a change in the power-law Tm. Notably, the onset temperature for this behavior varies with the perovskite composition. Additionally, it is found that this scattering process coincides with changes in fast-trapping behavior in MAPbI3 perovskite, which in turn alters recombination dynamics such as carrier lifetime and diffusion length. These results suggest that this scattering mechanism contributes to the defect tolerance of perovskites, providing valuable insights for further investigations.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"28 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987125","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}
