Perovskite-based transparent pn junction in CuI/SrTiO3 toward enhanced photoelectric response via interfacial homogeneous perovskite LaCoO3 transition layer

Applied Physics Letters, Journal Year: 2025, Volume and Issue: 126(9)

Published: March 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.

Abstract Altering the edge sites of 2D MXenes for electrochemical dinitrogen reduction reaction (ENRR) is widely reported, whereas activation its relatively inert basal planes neglected. Herein, and optimization Ti 2 CT x (T = *F, *O, *OH) toward enhanced ENRR to ammonia reported. The balanced surface functionalization in regulates kinetics by regulating potential zero charge (E PZC ) work function (). Specifically, altered E enhances electric field localization screening at /water interface stabilizing transition state reducing energy (ΔE). Hydrodynamic voltammetry, situ Raman, post‐ENRR X‐ray spectroscopy suggest faster kinetics, via an associative distal pathway, with *OH *F terminated 3+ as dominant active over surface. achieves yield 35.2 Faradaic efficiency 5.9% 0.05 m H SO 4 , which further improves 49% 0.5 NaBF . strategy concurrently modulates via, proton‐repelling functional groups (*F) on electrode weak proton donor electrolytes (NaBF ). This suppresses HER minimizes competition sites, promotes selective nitrogen activation, thereby boosting efficiency.
