摘要：
A transparent pn junction comprising ZnCo2O4/La(Cu0.2Co0.2Ni0.2Fe0.2 Mn-0.2)O-3 quantum dots(QDs)/LaAlO3 was synthesized by the sol-gel-annealing method. The ZnCo2O4/LaHEO QDs/LaAlO3 achieves high transmittance of similar to 85 %, obvious photoelectric enhancement of similar to 4.3 x 10(3)-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.
