Mo-based palmeirite oxide A2Mo3O8 is an emerging electrocatalyst, exhibiting a bipartite honeycomb lattice consisting of tetrahedral and octahedral sites with good conductivity. However, palmeirite as promising catalyst in electrocatalytic remains rarely touched. The rational design and clarification of the correlation between geometrical configuration modulation and electrocatalytic properties are challenging. Herein, an innovative strategy is reported to anchor thiospinel Co3S4 nanoparticles onto the surface of the Co2Mo3O8 nanosheet, which can trigger the spin electrons rearrangement, thus activating inert sites. According to the X-ray absorption spectroscopy, the Co2+─O─Co3+ bimetallic bridging sites with asymmetric bond polarization are constructed in the interface, which triggers a favorable spin transition of Co3+ from low to intermediate spin. Interestingly, the Co2Mo3O8/Co3S4 exhibits remarkable oxygen evolution reaction performance with an overpotential of 227 mV at 10 mA cm−2. At an industrial process temperature, it takes only 2.37 V for overall water splitting to obtain a large current density of 1 A cm−2. The theoretical calculation results confirm that lattice distortion-related spin transition optimizes the intermediate energy, thus enhancing the adsorption of the *OOH. This work highlights the potential of palmeirite for achieving industrial overall seawater splitting by geometrical configuration modulation and spin electrons rearrangement.

Organic photovoltaics (OPV) are a promising solar cell technology well-suited to mass production using roll-to-roll processes. The efficiency of lab-scale solar cells has exceeded 20% and considerable attention is currently being given to understanding and minimizing the remaining loss mechanisms preventing higher efficiencies. While recent efficiency improvements are partly owed to reducing non-radiative recombination losses at open circuit, the low fill factor (FF) due to a significant transport resistance is becoming the Achilles heel of OPV. The term transport resistance refers to a voltage and light intensity-dependent charge collection loss in low-mobility materials. In this perspective, it is demonstrated that even the highest efficiency organic solar cells (OSCs) reported to-date have significant performance losses that can be attributed to transport resistance and that lead to high FF losses. A closer look at the transport resistance and the material properties influencing it is provided. How to experimentally characterize and quantify the transport resistance is described by providing easy to follow instructions. Furthermore, the causes and theory behind transport resistance are detailed. In particular, the relevant figures of merit (FoMs) and different viewpoints on the transport resistance are integrated. Finally, we outline strategies that can be followed to minimize these charge collection losses in future solar cells.

Constructing high-efficiency platinum (Pt)-based catalysts for methanol oxidation reaction (MOR) by suppressing the intermediate COads generation is strongly desired and remains a grand challenge. Herein, the concept of holding O-bridged triple sites is documented to strengthen “non-CO” pathway selectivity by forming HCOO− species during MOR. The obtained Ga-O-PtPd triple sites via grafting the single-atomic Ga sites on PtPd nanosheets achieves a high current density of 3.05 mAcm−2 of MOR, which is 5.65 times higher than commercial Pt/C (0.54 mAcm−2), as well as remarkably stability and COads poison resistance. The CO diffuse reflectance infrared Fourier transform spectroscopy (CO-DRIFTS) results reveal that Ga-O-PtPd triple sites present a weak CO binding ability, reducing the generation of COads intermediate. In addition, the Ga-O-PtPd-based Zn-methanol-air batteries present an excellent activity and stability compared with commercial catalysts.

Achieving commercial viability for organic solar cells (OSCs) requires non-toxic, non-halogenated solvent processing. However, poor solubility and suboptimal morphology of commonly used active layer materials have been limiting their non-halogenated solvent applications for high-performance OSCs. This study introduces a novel random terpolymer, PM7-TTz50, designed to overcome these challenges. By incorporating 50 mol% of a co-planar thiophene-thiazolothiazole (TTz) unit into the PM7 backbones, the resulting terpolymer achieves enhanced solubility in eco-friendly solvents. Furthermore, PM7-TTz50's strong aggregation tendency, coupled with high-boiling-point solvent processing—which prolongs aggregate/crystal growth—enhances molecular stacking and ordering. This approach supports efficient charge transport and minimizes non-radiative recombination, yielding power conversion efficiencies (PCEs) exceeding 19% and over 16% w/o solvent additives. Additionally, PM7-TTz50 demonstrates broad compatibility with various non-fullerene acceptors (NFAs), leading to enhanced material uniformity and reproducibility in device fabrication.

Anode-free aqueous zinc (Zn) metal batteries (AFZMBs) possess an optimal battery architecture configuration because no excess Zn source is involved in the charge/discharge processes, rendering it feasible to enhance the energy density of batteries. However, rapid capacity fading due to the unstable anode-side current collector/electrolyte interfacial chemistry, which results in Zn dendrite growth, impedes their practical application, especially in quasi-solid-state AFZMBs. Herein, a robust bilayer interphase design strategy between a gel electrolyte and a copper current collector is proposed to achieve high-energy and stable quasi-solid-state AFZMBs. Utilizing the upper mass transfer layer to regulate rapid Zn ion transport and the lower zincophilic electron transfer layer to induce initial uniform Zn nucleation and balance the surface electric field, uniform dendrite-free Zn deposition and prominent reversibility are achieved. Therefore, the robust bilayer interphase design strategy significantly improves the cycling stability of quasi-solid-state Zn//I2 batteries. Additionally, the fabricated quasi-solid-state AFZMBs employing a pre-intercalated VO2 cathode deliver attractive energy and power densities (186.1 Wh kg−1/470 W kg−1 and 145.3 Wh kg−1/1.74 kW kg−1, based on the active material). Moreover, the successful extension of the bilayer interphase design to flexible AFZMBs offers a promising pathway for the development of wearable electronic devices.

Indium sulfide (In2S3) as water splitting photocatalyst has been broadly investigated due to its narrow bandgap (2.0–2.3 eV) and optimized opto-electronic properties. However, In2S3 still suffers from a rapid photogenerated charge carrier recombination rate. In addition, the main group metals (such as In) lack active d-orbital electrons for catalysis, thus limits activation of intermediates during catalytic water splitting reaction. Herein, to overcome the above limitations of In2S3, In2S3/TiO2 heterojunction with sulfur defects are constructed by temperature control strategy. The sulfur vacancy (Sv) can induce the electron density transformation of In 5p-orbital from localized states to delocalized states, which efficiently enhances the chemical affinity to *OOH. Thus, the p-orbital interaction between In and O atoms greatly facilitates the rate-determining step (*OOH → *+O2), realizing a high O2 yield rate of 10.00 µmol cm−2 h−1 at 1.23 V versus RHE. Furthermore, the heterogeneous structure also can enhance interfacial electric field (IEF) and stability for promoting oxygen generation. This work provides an efficient pathway to improve photoelectrochemical (PEC) activity by manipulating p-orbital electron delocalization of main group metals through defect engineering.

Vacancy-ordered Cs2SnX6 perovskites, with low-toxicity and high stability, have emerged as promising photocatalysts for hydrogen evolution reaction (HER). However, most Cs2SnX6 and derivatives have low catalytic activity mainly due to their insufficient light utilization efficiency. Herein, a simple in situ method is introduced to sensitize Cs2PtSnCl6 with Eosin Y (EY), forming EY-Cs2PtSnCl6 for HER in aqueous solution. Various characterizations indicate that the EY is immobilized onto the Cs2PtSnCl6 during the synthesis process. The EY-Cs2PtSnCl6 displayed extended light absorption range and efficient charge transfer from EY to Cs2PtSnCl6. The resulting EY-Cs2PtSnCl6 material exhibits high HER rate of 17.6 mmol g−1 h−1, ≈1760 folds than that of the pristine Cs2PtSnCl6. This work demonstrates an effective method to construct dye-sensitized perovskites and highlights the importance of interaction between dye and perovskite. It provides useful guidance for the design of new perovskite-based photocatalysts and it will advance the development of perovskites for solar energy conversion into renewable fuels.

Metal halide perovskite-based devices can exhibit exceptional optoelectronic performance at relatively high defect densities, a phenomenon commonly referred to as defect tolerance, which is one of the most important features of metal halide perovskites (MHPs). Defect tolerance is previously thought to be a static property, determined solely by the composition and manufacturing process. However, recent studies have shown that the defect tolerance of MHPs is dynamic and can vary over time. For example, the power conversion efficiency of MHPs-based solar cells has been found to improve significantly under continuous illumination. Although this is a unique self-optimization behavior of MHPs, it can seriously affect the stability of power output of MHPs-based solar cells in real-world operating conditions. In view of this, extensive research has been conducted, but the physical mechanism of this photoinduced dynamic defect tolerance (DDT) has remained inconclusive, as both the mechanisms and experimental phenomena continue to be subjects of controversy. Therefore, a timely summarization on mechanisms related to DDT is urgently needed. In this review, a systematic overview is first provided of the experimental phenomena, characteristics, and influencing factors of the DDT. Following that, the proposed mechanisms for DDT are summarized, with a focus on carrier-defect and carrier-lattice interactions. Finally, the current challenges faced in DDT research are summarized and an outlook on the future developments is provided. This review aims to offer a comprehensive understanding of DDT in MHPs to enhance the performance and stability of MHPs-based solar cells, thereby facilitating the advancement and commercialization of these technologies.
{"title":"Dynamic Defect Tolerance in Metal Halide Perovskites: From Phenomena to Mechanism","authors":"Guangsheng Liu, Mehri Ghasemi, Qianwen Wei, Baohua Jia, Yu Yang, Xiaoming Wen","doi":"10.1002/aenm.202405239","DOIUrl":"https://doi.org/10.1002/aenm.202405239","url":null,"abstract":"Metal halide perovskite-based devices can exhibit exceptional optoelectronic performance at relatively high defect densities, a phenomenon commonly referred to as defect tolerance, which is one of the most important features of metal halide perovskites (MHPs). Defect tolerance is previously thought to be a static property, determined solely by the composition and manufacturing process. However, recent studies have shown that the defect tolerance of MHPs is dynamic and can vary over time. For example, the power conversion efficiency of MHPs-based solar cells has been found to improve significantly under continuous illumination. Although this is a unique self-optimization behavior of MHPs, it can seriously affect the stability of power output of MHPs-based solar cells in real-world operating conditions. In view of this, extensive research has been conducted, but the physical mechanism of this photoinduced dynamic defect tolerance (DDT) has remained inconclusive, as both the mechanisms and experimental phenomena continue to be subjects of controversy. Therefore, a timely summarization on mechanisms related to DDT is urgently needed. In this review, a systematic overview is first provided of the experimental phenomena, characteristics, and influencing factors of the DDT. Following that, the proposed mechanisms for DDT are summarized, with a focus on carrier-defect and carrier-lattice interactions. Finally, the current challenges faced in DDT research are summarized and an outlook on the future developments is provided. This review aims to offer a comprehensive understanding of DDT in MHPs to enhance the performance and stability of MHPs-based solar cells, thereby facilitating the advancement and commercialization of these technologies.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"38 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539148","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}
