The widespread application of MOFs in thermoelectricity has been hampered by their low conductivity and limited thermal stability. In this work, a uniform dispersion of MOFs within the Bi0.4Sb1.6Te3 matrix is realized. This results in dual benefits: the assurance of microstructural stability of MOFs within the composites and a significant enhancement in electrical transport of Bi0.4Sb1.6Te3 induced by the organic-inorganic interfacial electron transfer and energy filtration effect. Meanwhile, the 1-by-1-nm-tuned-pore and intricate hierarchical architecture of MOFs play a crucial role in diminishing thermal conductivity of Bi0.4Sb1.6Te3. Consequently, the notable thermoelectric performance of the Bi0.4Sb1.6Te3/0.5 wt% ZIF-8 nanocomposite is achieved, including a peak zT of 1.65, a remarkable maximum cooling ΔT of 71.6 K at Th = 300 K, and a record-high thermoelectric conversion efficiency of 6.7% at ΔT = 238 K. This study utilizes the unique structural features of MOFs, broadening their applications into the mid-temperature range within the field of thermoelectrics.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":null,"pages":null},"PeriodicalIF":32.5,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141462545","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, traditional manual methods often struggle to effectively control the key variables. This inherent challenge requires a paradigm shift toward automated platforms capable of precise and reproducible experiments. Herein, we use a fully automated device acceleration platform (DAP) to optimize the process parameters for preparing full perovskite devices using a two-step sequential technique in ambient air. 10 process parameters that have the potential to significantly influence device performance are systematically optimized. Specifically, we delve into the impact of the dripping speed of organic ammonium halide, a parameter that is difficult to control manually, on both perovskite film and device performance. Through the targeted design of experiments, we reveal that the dripping speed significantly affects device performance primarily by adjusting the residual PbI2 content in the films. We find that moderate dripping speeds, e.g., 50 µL/s, contribute to top-performance devices. Conversely, too fast or too slow speeds result in devices with relatively poorer performance and lower reproducibility. The optimized parameter set enables us to establish a Standard Operation Procedure (SOP) for additive-free perovskite processing under ambient conditions, which yield devices with efficiencies surpassing 23%, satisfactory reproducibility, and state-of-the-art photo-thermal stability. This research underscores the importance of understanding the causality of process parameters in enhancing perovskite photovoltaic performance. Furthermore, our study highlights the pivotal role of automated platforms in discovering innovative workflows and accelerating the development of high-performing perovskite photovoltaic technologies.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":null,"pages":null},"PeriodicalIF":32.5,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141462537","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}

Fabricating solar cell modules in large-area substrate takes a longer time to deposit and process the thin film than small area devices. Therefore, it is required to expand the processing window of the solution process. Here, we showed that combining N-methyl-2-pyrrolidone solvent with a cooling strategy can generate more stable FA-based perovskite intermediates in two-step deposition, realizing a longer annealing window. The power conversion efficiency (PCE) of 25.21% for small-area devices (0.045 cm2) and 23.60% for large-area devices (1.00 cm2) were achieved. It is found that cooling the intermediate phase at a temperature close to 0°C can suppress the formation of δ-phase FAPbI3 and expand the annealing window by 20-fold (from 9 min to 180 min). With the cooling strategies, we have successfully fabricated uniform perovskite films in large area of 45 cm2. PSC mini-modules made by this method achieved state-of-the-art efficiencies of 22.34% and certified efficiency of 21.51%. More importantly, even with an annealing delay time of 180 min, the modules attain decent PCE of 20.89%, showing an ultra-long process window for fabricating efficient PSCs. Our strategy of stabilizing the perovskite intermediate phase brings great flexibility to the large-scale production of perovskite solar modules.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":null,"pages":null},"PeriodicalIF":32.5,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141462428","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}

Herein, we in-situ encapsulate Fe3C nanoparticles (NPs), decorated by a thin carbon shell, onto porous S-doped Fe-NC two-dimensional carbon nanosheets. The membrane electrode assembly (MEA) applied with the hybrid Fe-S-NC/Fe3C catalyst in the cathode could achieve high power densities of 0.836 W cm-2 and 0.535 W cm-2 in H2-O2 and H2-air PEMFCs, respectively. Moreover, the catalyst exhibits excellent durability while applying in cathode of H2-O2 PEMFC with 75% of the original performance recovered after 68 h life-span test. Experimental results and density functional theory calculations indicate that the improvement of electrochemical activity and durability could be ascribed to the synergistic catalysis between porous S-doped Fe-NC and Fe3C NPs hybrid construction with lower energy barriers for the rate-determining step of the ORR.

Furthermore, sluggish ion transportation further compromises the cycling stability of LMBs/SMBs at low temperatures. To achieve stable operation of LMBs/SMBs at low temperatures, researchers have pursed numerous efforts including the electrolyte optimization aimed at creating stable SEI and suppress the metal dendrites under low temperature circumstance.
