Опубликована: Март 1, 2025

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.

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). This helps reduce safety hazards during process demonstrates great application value fields batteries capacitors.
