Applied Physics Letters, Год журнала: 2025, Номер 126(9)

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.

Опубликована: Май 13, 2025

Abstract Reasonable construction and design of photo‐catalysts have been widely concerned in promoting hydrogen production. Herein, a novel Ni(OH) 2 /ZIF‐67(NZ) S‐scheme heterojunction is proposed for photocatalytic Meantime, through the coordination interface keys, separation transfer photo‐generated charges are expedited. Leading to an effectively enhanced evolution performance due synergistic effect built‐in electric field coordination. The production rate NZ‐ 20 within 4 h reaches 4364.89 µmol g −1 , which 17.79 times higher than that 19.46 ZIF‐67. Meanwhile, situ X‐ray Photoelectron Spectroscopy (XPS) studies confirm mechanism photogenerated charge transfer. This work improves efficiency provides new thought heterojunction.
