Utilizing photoluminescent quantum dots (QDs) as a luminescent down-shifting (LDS) layer to convert high-energy photons into lower-energy ones is a prominent approach to reducing parasitic absorption of silicon heterojunction (SHJ) solar cells. Here, a ray-optic model is presented to gain insight into light conversion contribution on the short-circuit current density (Jsc) of the SHJ solar cell with an LDS layer. The correlation reveals that the primary factors impacting external quantum efficiency (EQE) are the absorption coefficient at short wavelengths and the photoluminescence quantum yield (PLQY) of the LDS layer. Notably, PLQY is dominant in determining the contribution to the device efficiency if the LDS layer can harvest all the parasitic light, particularly when there is no surface reflectance change. Furthermore, the EQE spectrum of high-efficiency SHJ solar cells is experimentally investigated with the QDs LDS layer to validate the model, revealing that it aligns well with the experiment results. Employing a MgF2/QDs LDS layer, the Jsc with 0.50 mA cm−2 is enhanced, yielding the SHJ solar cells with an efficiency of over 22.3%. The work develops a broadly applicable model that aids in screening suitable photoluminescent materials for LDS layer applications in photovoltaic devices and elucidates the theoretical contributions to EQE.

Antimony sulfide (Sb2S3) is a promising absorber for single-junction and tandem solar cells. Unfortunately, its quasi-1D structure holds large void space and complex deep defects, which prepare high-quality absorber layers and pose a significant challenge. In this work, ethylenediaminetetraacetic acid disodium salt (EDTA-2Na) is developed as an additive to regulate the reaction kinetics for Sb2S3 deposition. The strong chelating interaction between EDTA-2Na and Sb3+ significantly suppresses homogeneous nucleation byproducts and retards the deposition rate of the absorber layer. On the other hand, the SnO2/CdS double buffer layers could enhance light transmittance, and herein NH4F is successfully applied to improve the dispersion of SnO2 nanoparticles and increase the n-type conductivity of SnO2 film through fluorine doping. Finally, the resulting Sb2S3 solar cells obtained significantly improved fill factor (FF) and short circuit current density (JSC) values of 64.81% and 17.91 mA cm−2, and its power conversion efficiency (PCE) reached a new record value of 8.26% (8.08% certified). This work offers new insights into addressing key challenges that hinder the development of Sb2S3 solar cells.

As Sodium-ion battery (SIB) technology progresses toward commercial viability, sustainable end-of-life (EOL) management is critical. Methods for recycling key components such as hard carbon (HC), a negative electrode material, remain underexplored. This study introduces a direct and efficient recycling approach for HC from production scrap and EOL cells using “ice-stripping” followed by a low-temperature binder negation at 300 °C under nitrogen. The effects of temperature on HC structural integrity and electrochemical performance are comprehensively characterized using XRD, Wide-Angle X-ray Scattering (WAXS), and XPS. Heating above 400 °C induces irreversible damage to HC's graphene layers and modifies the carbon surfaces, resulting in poor electrochemical performance. However, HC reclaimed at 300 °C retains near-pristine electrochemical performance, with capacities of 243 mAh g⁻¹ (scrap) and 228 mAh g⁻¹ (EOL) after 50 cycles. Full-cell configurations demonstrates robust cycling stability, with 86% and 89% capacity retention after 200 cycles for HC derived from scrap and EOL cells, respectively. This work highlights the potential of lower-temperature, direct recycling to enable a circular economy for SIBs. The findings set a benchmark for developing sustainable recycling methods for HC and other SIB components.

Perovskite Solar Cells
The commonly used lifetime indicator T80 of perovskite solar cells is shown to be season/climate dependent by outdoor measurements. The climate parameter mainly affecting the lifetime is the ambient temperature, while the solar irradiance plays a more minor role. Indoor light cycling experiments combined with temperature cycling are suggested to provide closely related simulation for outdoor lifetime/degradation.

Layered Mn-rich materials are regarded as a promising cathode candidate for Na-ion batteries (NIBs) owing to its environmentally friendly nature, decent theoretical capacities, and relatively low cost. However, the irreversible phase transition originating from the Jahn–Teller distortion attributed to high-spin Mn3+ (t2g3eg1) during deep sodiation triggers serious structural degradation followed by capacity decay. Herein, the incorporation of borate-anion groups either into the bulk (BO33−) or on the surface (BO45−) successfully modulates the local-structure environment of the P2-type layered cathode, changing the lattice parameters and valence states of the transition metals inside. The optimized Na0.734Ni0.207Mn0.694Co0.098(B0.063Ox)O2-x (B-NCM) can remit a P2-P’2 phase transition by mitigating the inherent Jahn–Teller distortion of MnO6 octahedra, allowing a reversible phase transition with reduced strain even after deep sodiation to 1.5 V. The B-NCM cathode exhibits excellent capacity retention, reaching 82.02% after 200 cycles. In addition, the modulated local structure inside B-NCM helps to relieve Na+/vacancy ordering, enhancing Na+ diffusivity and rate capability compared to a pristine NCM analo. This work demonstrates a novel approach based on the incorporation of glassy anion groups into both surface and bulk to improve the electrochemical properties of layered Mn-rich cathode materials.

All-solid-state lithium-metal batteries (ASSLMBs) with sulfide solid electrolytes have gained significant attention due to their potential for high energy density and enhanced safety. However, their development has been hindered by rapid lithium dendrite growth, low coulombic efficiency, poor battery rate performance, and poor cycling stability, posing a major obstacle to their commercialization. Herein, a multifunctional composite sulfide electrolyte (M-CSE) is reported that is dynamically stable with lithium metal, promoting uniform Li+ deposition without dendrites. The resulting ASSLMBs exhibit an areal capacity of 10 mAh cm−2, an energy density of 219 Wh kg−¹, and a current density of 3.76 mA cm−2, with a capacity retention of 95.04% after 500 cycles at 0.5C. The assembled lithium swagelok cell and solid-state lithium-metal pouch cells have relatively low pressures, with the swagelok cell stack pressure ≈30 MPa and the pouch cell stack pressure also ≈2 MPa. More importantly, mass production of ultra-low-pressure pouch cells is realized by 3D printing technology, marking a crucial breakthrough for practical applications.

The recently emerged chloride solid electrolytes have garnered significant attention due to their superior ionic conductivity, wide electrochemical stability window, and exceptional compatibility with high-voltage oxide cathodes. Nevertheless, the currently cost-effective Zr-based chloride solid electrolytes face significant challenges, including low ionic conductivity and poor moisture stability. Herein, a versatile Zn2+-doped Zr-based chloride electrolyte is presented, designed to meet the aforementioned requirements. The optimized Li2.4Zr0.8Zn0.2Cl6 exhibits an improved ionic conductivity of 1.13 mS cm−1 at 30 °C. Simultaneously, the Li2.4Zr0.8Zn0.2Cl6 also demonstrates impressive moisture stability, maintaining its structural integrity after exposure to humid air. The mechanism underlying the enhanced moisture stability of Li2.4Zr0.8Zn0.2Cl6 is further elucidated by density functional theory calculations. Most notably, whether coupled with LiCoO2 or LiNi0.8Mn0.1Co0.1O2 cathodes, Li2.4Zr0.8Zn0.2Cl6-based all-solid-state batteries demonstrate exceptional cycling stability and rate performance. This high ionic conduction and moisture-resistant chloride electrolyte holds great promise for significantly advancing the commercialization of all-solid-state lithium batteries.

The mechanism underlying the enhanced moisture stability of Li<sub>2.4</sub>Zr<sub>0.8</sub>Zn<sub>0.2</sub>Cl<sub>6</sub> is further elucidated by density functional theory calculations. Most notably, whether coupled with LiCoO<sub>2</sub> or LiNi<sub>0.8</sub>Mn<sub>0.1</sub>Co<sub>0.1</sub>O<sub>2</sub> cathodes, Li<sub>2.4</sub>Zr<sub>0.8</sub>Zn<sub>0.2</sub>Cl<sub>6</sub>-based all-solid-state batteries demonstrate exceptional cycling stability and rate performance. This high ionic conduction and moisture-resistant chloride electrolyte holds great promise for significantly advancing the commercialization of all-solid-state lithium batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"21 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486044","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}
