Perovskite Solar Cells

In article number 2404234, Parthasarathy Venkatakrishnan, Yuan Jay Chang, Chih-Ping Chen, and co-workers propose utilizing polyarene-based molecules as hole-selective layers (HSL) to passivate interfacial defects in perovskite solar cells (PSCs). The optimized HSL efficiently mitigates perovskite defects, promotes energy alignment at the HSL/perovskite interface, and enhances the carrier transport efficiency of PSCs. The resulting indoor light efficiency is 41.80 ± 0.57% under 3000K LED illumination (1000 lux) with promising long-term stability.

In Situ Construction of IrOx Nanofilm on TiOx for Boosting Low-Ir Catalysis in Practical PEM Electrolyze

Exploring low-iridium (Ir) electrocatalysts for oxygen evolution reaction (OER) is exigent to promote the commercialization of proton electrolyte membrane water electrolyzers (PEMWEs). Herein, the study presents a scalable and facile strategy to in situ construct an IrOx nanofilm continuously coated on TiOx support as efficient and durable OER catalyst through one-step annealing of Ir-salt-adsorbed titanium-based metal–organic frameworks (MOFs) precursor. The unique nanofilm structure forms a continuous p-n junction interface, endowing a strong interfacial electron transfer from TiOx to IrOx and also ensuring a well-connected conductive network in the anodic catalytic layer due to the continuous dispersion of IrOx. The optimal catalyst requires a low overpotential of 233 mV at 10 mA cm−2 with a 40-fold of com. IrO2 in mass activity. The assembled PEMWE shows a cell voltage of 1.762 V at 1 A cm−2 with ≈220 h durable operation under start/shut-down operation. Operando characterizations and theoretical calculation reveal that the p-n junction not only reduces the energy barrier of water dissociation and deprotonation step of *OOH boosting OER kinetics but also prevents oxidation of Ir sites to form soluble Ir species that improves durability. This work offers a new avenue to rationally design and synthesize efficient low-Ir OER catalyst for PEMWE application.

All solid-state lithium-sulfur batteries (ASSLSBs) demonstrate tremendous potential in the next-generation energy storage system. Nevertheless, the incomplete conversion of Li<sub>2</sub>S<sub>2</sub> to Li<sub>2</sub>S within the sulfur electrode imposes a substantial impediment on the capacity release. Herein, the nickel single-atom catalyst (NiNC) materials are employed to ameliorate the sluggish reaction kinetics of polysulfides.

Solid electrolyte interphase (SEI) plays a crucial role in stabilizing the anode-electrolyte interface of lithium-ion batteries. To date, extensive efforts are dedicated to the regulation of the SEI's compositions, instead the dissolution of the SEI in the electrolyte, an important factor that significantly influences the interfacial stability, received less attention. In this work, it is discovered for the first time that the dissolution of propylene carbonate (PC)-derived SEI can be restrained by employing tetramethylene sulfone (TMS) as the main solvent, thereby markedly enhancing the interfacial stability of Li||graphite half-cell and high-voltage graphite||LiCoO2 full cell. Undoubtedly, this work provides a new electrolyte design principle for developing many solvents that are previously considered detrimental in batteries to establish robust interfaces by minimizing the solubility of SEI.

Configuration Design and Interface Reconstruction to Realize the Superior High-Rate Performance for Sodium Layered Oxide Cathodes

Charge transfer at the electrode/electrolyte interface and mass transfer within the electrode are the two main factors affecting the high-rate performance of O3-type layered oxide cathodes for sodium-ion batteries. Here a multidimensional lanthurization strategy is proposed to construct the surface LaCrO3 heterostructure and create a Cr─O─La configuration for O3-type NaCrO2. The electrified heterogeneous LaCrO3 induces a built-in electric field to accelerate charge transfer at the interface. Meanwhile, the Cr─O─La configuration in the transition metal layer leads to local charge aggregation, weakens the interaction force between Na─O, and reduces the Na+ migration barrier. This strategy significantly improves the electrochemical reaction kinetics and the structural reversibility of the layered oxide cathode. As a result, the designed stoichiometric ratio Na0.94Cr0.98La0.02O2 electrode exhibits remarkable rate performance (101.8 mAh g−1 at 40 C) as well as outstanding cycling stability (83.1% capacity retention at 20 C for 2000 cycles) in a half-cell, along with a competitive full battery performance (89.3% after 500 cycles at 2 C). This study provides a promising route to achieve capacity presentation and retention of layered oxide cathode materials at high-rate.

The design of efficient oxygen reductionreaction (ORR) catalyst with fast kinetics is crucial for high-performance Zn–air batteries but remains a challenge. Herein, inspired by the oxidative respiratory chain of prokaryotes, an ORR electrocatalyst is reported by mimicking the microstructure of Staphylococcus aureus and simitaneously utilizing this low-cost cell as the precursor. The catalyst consists of MnO2/Co2P nanocomposites support on Staphylococcus aureus-derived hollow spherical carbon, which not only accelerates electron transfer for improved intrinsic reaction kinetics, but also creates an OH concentration gradient for enhanced mass transfer efficiency. Such bio-inspired and derived ORR catalyst enables rechargeable Zn–air batteries with ultra-long cycling stability of more than 2800 h at a high capacity of 810.3 mAh g−1, which is superior among the reported bio-derived oxygen catalysts. A flexible Zn–air battery based on the bio-inspired and derived catalyst is also assembled, and it well integrates with a wireless flexible electronic skin.

Elemental Stability Rules for High Entropy Disordered Rocksalt Type Li-Ion Battery Positive Electrodes

High entropy disordered rocksalt (HE-DRX) Li-ion battery positive electrodes have gained attention as a potential alternative to commercialized positive electrodes, aiming to eliminate or minimize the use of Ni/Co while maintaining competitive electrochemical performance. Despite their potential, understanding the intricate elemental stability across the vast HE-DRX chemical landscape remains a significant challenge. In this study, we tackle this challenge by conducting a comprehensive data-driven phase diagram analysis of 18810 potential HE-DRX compositions, each featuring common Li and F stoichiometries. Leveraging a charge balance algorithm, we systematically explore redox stability and phase stability, unveiling critical insights into chemical stability rules within the HE-DRX design space. The analysis also uncovers untapped potential of Cu as redox-active centers, with Sb and Sn contributing as stable charge compensators. The utilization of these elements is seldom reported in the literature but has been validated by the successful experimental synthesis of materials Li21Zr3Ti3Mn2Fe5Cu2O36 and Li21Mn2Ti3Fe5Cu2Sn3O36.

Adjustable Selectivity for CO2 Electroreduction to Ethylene or Ethanol by Regulating Interphases Between Copper and Tin Oxides

Enhancing the selectivity of C2 products and revealing the reaction mechanisms in CO2 electroreduction reaction (CO2RR) remain challenging. Regulating the interphases in catalysts is one of the most promising pathways. Herein, the interphases between copper (Cu) and tin (Sn) oxides are regulated by controlling the degree of reduction during the self-assembly process, which exhibits obvious different selectivity to ethylene and ethanol, respectively. The interphase in Cu-SnO2 exhibits selectivity to ethanol as high as 74.6%, while the interphase in Cu2O-SnO2 shows selectivity to ethylene as high as 71.4% at –0.6 V versus RHE. In situ Fourier-transform infrared spectroscopy measurements and density functional theory calculations demonstrate that the interphase in Cu-SnO2 shows strong electron interaction, preferentially forming the key *COH intermediates for asymmetrical C─C coupling to produce ethanol. In contrast, Cu2O-SnO2 possesses oxygen vacancies at both sites, thus enriching *CO intermediates for symmetrical C─C coupling to produce ethylene at the interphase. The findings in this work offer an advanced strategy by regulating the interphases to adjust C2 selectivity in CO2RR.
