By leveraging a synergistic approach that combines photoluminescence, admittance spectroscopy and cathodoluminescence techniques, the theoretical models of radiative recombination in Cu2ZnSnS4 kesterite are revisited, allowing for a comprehensive clarification of both radiative and nonradiative recombination loss effects of VOC-def in the kesterite bulk and at interfaces. This quantitative analysis of VOC-def reveals that Cu/Zn disorder remains a fundamental limitation for kesterite solar cells, comparable to deep-level defects. Specifically, it is demonstrated that the asymmetric photoluminescence band commonly observed in Cu2ZnSnS4 consists of two competing components: tail-impurity recombination (conduction band → CuZn) and quasi-donor-acceptor-pair recombination (ZnCu → CuZn). These findings confirm that Cu/Zn antisite defects and related potential fluctuations reduce the effective bandgap. Furthermore, it is confirmed that band tails in kesterite are the result of electrostatic potential fluctuations and bandgap fluctuations. The amplitude of the electrostatic potential fluctuations is estimated to be ≈30 meV. Bandgap fluctuations in kesterite are experimentally distinguished from electrostatic potential fluctuations for the first time, which leads to a bandgap contraction of about 130 meV. These studies provide crucial theoretical support for the advancement of kesterite photovoltaic technology.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"33 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142904757","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 in situ conversion of Pt4+ and Ru3+ is creatively achieved into highly dispersed, small-sized heterojunction clusters in the confined space by reductant preset framework materials, and these clusters benefited from the hollow carbon spheres gap supramolecular self-assembly strategy to achieve high exposure. The intra-cluster Ru→Pt electron transfer and induced electronic structure modulation enhance the adsorption and activation of H2O molecules at the interface, accelerating the desorption coupling of [H] at the Pt or Ru site. As a catalyst, PtRu/BNHCSs have achieved significant hydrogen production from electrolyzed water in multiple scenarios, exceeding the performance of the commercial Pt/C catalyst. These scenarios include high-current water splitting to hydrogen in both pH-neutral and simulated seawater, direct seawater hydrogen production, and anion-exchange membrane integrated continuous and efficient electrolytic hydrogen production.

In this study, an effective synergistic electrocatalytic strategy involving a 3D Mn-NiSe2/GF electrocatalyst and aminoxyl is proposed and demonstrated for the multi-hundred-gram scale synthesis of the chiral drug intermediate Levetiracetam. The mild reaction conditions of electrocatalysis effectively preserves the stereochemical configuration adjacent to the oxidation site, achieving yields of up to 93.5% and enantiomeric excess retention of 99.1% through process intensification in a continuous flow electrolyzer.

Metal chalcogenides anode materials based on alloying or conversion reactions are widely studied because of their high theoretical capacities and rich redox reactions. However, their intrinsic limitations such as high voltage hysteresis and large volume expansion hinder their further applications. The construction of heterostructures has become an attractive strategy to alleviate the above issues. The formation of built in electric fields (BIEFs) at the heterointerfaces will accelerate the migration of Na+ and electrons. Moreover, heterostructures can also enhance the structural stability, generate more active sites and provide additional capacity. It is worth noting that heterointerfacial properties play a significant role in promoting the overall electrochemical performance of the heterostructures. However, a systematic understanding of their interfacial engineering is currently lacking. This article reviews the research progress of metal chalcogenides-based heterostructure anode materials in the near term. First, the definition, classification and the roles of heterostructures are introduced. Second, the detailed research progress of the metal chalcogenide-based heterostructures anodes in SIBs is discussed.

The significant role of strain engineering in the photocatalytic reduction of carbon dioxide to solar fuel using semiconductor catalysts is reviewed in this paper. Specifically, the design strategies of strain catalysts and the crucial role of strain on CO2RR are examined.

Combining RP with perovskite (P) can provide superior electrocatalytic activity toward hydroxide oxidation and reduction reaction, driving higher efficiency in solid oxide cells (SOC). This work provides a novel approach to enhancing SOC performance by employing A-site Ce-substituted Sr0.6Pr0.4-xCexMnO3 (x = 0.1-0.3) electrodes, investigating their phase evolution, crystal properties, and cation oxidation states under oxidizing and reducing atmospheres. X-ray diffraction analysis of heat-treated powder in a reducing atmosphere revealed forming mixed P and RP structures at 600–800 °C for x = 0.1 and 0.2, which provides excellent conductivity and electrocatalytic activity. Consequently, outstanding cell performance is achieved, with low polarization resistances of 0.053 ± 0.004 Ω cm2 at 800 °C. The voltage response at different current densities in an electrolyte-supported cell revealed a high power density of 1.084 W cm−2 in fuel cell operation and a current density of 1.00 A cm−2 at the thermoneutral voltage at 850 °C in steam electrolysis.

This work presents an in-house built attenuated total reflection fourier-transform infrared (ATR-FTIR) spectroscopy cell equipped with an internal temperature-control unit. This cell is used for operando characterization of interfacial processes between plated Li and polymer during Li plating/stripping. As a proof of concept, a polymer electrolyte (cr-PEO10LiTFSI) containing poly(ethylene oxide), Li bis-(trifluoromethanesulfonyl)imide and crosslink-initiator benzophenone (BP) is introduced on a copper mesh as current collector at 60 °C. The developed ATR-FTIR spectroscopy setup provides detailed insights into the electrolyte degradation and reveals the crystallinity transformation of PEO at the interface during plating. Moreover, for the first time, the degradation of BP is observed. This compound, often overlooked in electrolyte systems due to its low concentration, is found to play a significant role in the interfacial electrochemistry process. Overall, this study provides a comprehensive overview of the characterization on the PEO electrolyte-lithium metal interface and introduces a novel perspective on the reaction of BP as a crosslinking initiator in the solid-state batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"1 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901869","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}

Whereas the first stage contains only material research, the later stages are concerned with the development from lab-scale devices to large-area modules, and properties such as device size as well as processing methods are adapted step-by-step toward commercializable techniques. The stages are connected by gates that specify the criteria that must be met for a material or process to be transferred to the next stage. In addition, a literature survey for the keywords “perovskite” and “module” is performed. This analysis shows that most of the reported modules have an area between 10 cm2 and 20 cm2, corresponding to stage 3 or TRL 5 in the scheme, and operational stability is often incompletely reported. These findings analysis indicate a significant gap in the research focus on large-area modules and elevated stress and field tests, which are essential for transitioning to commercial applications.
