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.

Advanced electrocatalysts capable of bifunctional catalysis for formic acid oxidation (FAOR) and hydrogen evolution reaction (HER) have garnered significant attention due to their exceptional energy efficiency. In this research, we meticulously designed a PdCu bimetallene characterized by numerous crystalline/amorphous (c/a) interfaces robust d–sp orbital hybridization, achieved integrating the p-block metalloid boron within matrix (B-PdCu-c/a). The B-PdCu-c/a revealed multitude surface atoms unsaturated defect sites, offering abundant catalytic active sites an optimized electronic structure. B2-PdCu-c/a exhibited best performance in FAOR HER, achieving mass activity 1106 mA mgcat–1 overpotential 52 mV, respectively. Significantly, two-electrode configuration B2-PdCu-c/a∥B2-PdCu-c/a attained low cell voltage 0.19 V at 10 cm–2 during acid-assisted overall water splitting. Density functional theory (DFT) calculations indicated that c/a interface engineering hybridization synergistically pristine bimetallene. This led elevation d-band center accumulation charge interface, which enhanced adsorption intermediates, facilitated C–H bond cleavage, balanced adsorption–desorption hydrogen, thereby improving electrocatalytic activities study not only presents viable strategy effectively tuning but also offers valuable insights into development electrocatalysts.
