Abstract

A transparent pn junction comprising ZnCo₂O₄/La(Cu_0.2Co_0.2Ni_0.2Fe_0.2 Mn_0.2)O₃ quantum dots(QDs)/LaAlO₃ was synthesized by the sol–gel-annealing method. The ZnCo₂O₄/LaHEO QDs/LaAlO₃ achieves high transmittance of ∼85 %, obvious photoelectric enhancement of ∼4.3 × 10³-folds to intrinsic ZnCo₂O₄/LaAlO₃, preeminent stability in 5 months. It primarily attributes to the LaHEO QDs. Besides appropriate Fermi level/high quantum yield, the LaHEO QDs own carrier inducing/injecting/driving via the Cu-Co-Ni-Fe-Mn polymetallic metastable ionic coupling synergism can ameliorate carrier dynamics for optimizing power conversion efficiency-transparency balance. Furthermore, the inorganic ZnCo₂O₄, LaHEO QDs and LaAlO₃ show good structural and modified stability for its actual long-term applications.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
