A transparent pn junction comprising CuI/LaCoO3 QDs/SrTiO3 was synthesized using the solgel-hydrothermal-freeze drying-sputtering in situ iodization method. The achieves transmittance of ∼85%, photoelectric enhancement ∼2.2 × 103-fold to intrinsic CuI/SrTiO3, and good stability 5 months. It can be primarily attributed LaCoO3 QDs. In addition appropriate Fermi level high QY, QDs with carrier inducing–injecting–driving ameliorate dynamics for PCE-transparency balance, meanwhile increasing hole by Cu vacancy. Furthermore, CuI, LaCoO3, SrTiO3 maintain structural potential devices.

Abstract Global interest in lithium–sulfur batteries as one of the most promising energy storage technologies has been sparked by their low sulfur cathode cost, high gravimetric, volumetric densities, abundant resources, and environmental friendliness. However, practical application is significantly impeded several serious issues that arise at cathode–electrolyte interface, such interface structure degradation including uneven deposition Li 2 S, unstable interphase (CEI) layer intermediate polysulfide shuttle effect. Thus, an optimized along with electrodes required for overall improvement. Herein, we comprehensively outline challenges corresponding strategies, electrolyte optimization to create a dense CEI layer, regulating S pattern, inhibiting effect regard solid–liquid–solid pathway, transformation from solid–solid pathway interface. In order spur more perceptive research hasten widespread use batteries, viewpoints on designing stable deep comprehension are also put forth.

A transparent pn junction comprising CuCrO2/Ba(Ti0.2Zr0.2Sn0.2Hf0.2Ce0.2)O3/WO3 was synthesized using a sol-gel-hydrothermal-annealing method. The CuCrO2/BaTiZrSnHfCe/WO3 achieves transmittance of ∼83%–88%, with photovoltaic enhancement ∼4.0 × 103-folds compared to the intrinsic device [photovoltaic conversion efficiency (PCE) ∼1.22%], and it also demonstrates good stability over 5 months. This is mainly attributed BaTiZrSnHfCe HEO solid solution. In addition an appropriate Fermi level/high QY, HEO, carrier inducing/injecting/driving by synergism high entropy lattice distortion charge compensation, can improve kinetic equilibrium for achieving PCE-transparency while increasing holes via Cu vacancies/interstitial oxygen. Moreover, inorganic CuCrO2, WO3 maintain structural stability, indicating promising applications in optoelectronic devices.

Prussian blue analogues (PBAs) show great promise as cathode candidates for aqueous zinc-ion batteries thanks to their high operating voltage, open-framework structure, and low cost. However, suffering from numerous vacancies crystal water, the electrochemical performance of PBAs remains unsatisfactory, with limited capacity poor cycle life. Here, a simple coprecipitation method is shown synthesize well-crystallized cobalt hexacyanoferrate (CoHCF) small amount water specific surface area. Benefitting two redox-active sites, CoHCF could deliver 104.6 mA h g-1 at 0.02 A 72 1 g-1, good retention 92.4% after 300 cycles 0.5 g-1. Several kinetic tests indicate that reaction dominated by capacitive behavior diffusion coefficient Zn2+ ions approximately 10-9 cm2 s-1. Furthermore, ex-situ XRD indicated reversible insertion/extraction without any phase transition.

Abstract Precise regulation of the platform capacity/voltage electrode materials contributes to efficient operation sodium-ion fast-charging devices. However, design such is still in a blank stage. Herein, based on tunable metal–organic frameworks, we have designed novel material system—two-dimensional high-entropy frameworks (HE-MOFs), which exhibits unique properties sodium storage and vital importance for realizing batteries. Furthermore, found that effect can regulate electronic structure, migration environment, active sites, thereby meeting requirements Impressively, HE-MOFs maintains reversible specific capacity 89 mAh g −1 at current density 20 A . It presents an ideal voltage plateau approximately 0.5 V, its increased 122.7 , far superior Mn-MOFs (with no capacity).
