Synthesis and electrochemical performance of α-Al₂O₃ and M-Al₂O₄ spinel nanocomposites in hybrid quantum dot-sensitized solar cells.

ABSTRACT: The aim of this study is to describe the performance of the aluminum oxide nanoparticle and metal aluminate spinel nanoparticle as photo-anodes in quantum dot photovoltaic. By using a sol-gel auto combustion method, Al₂O₃ NPs, CoAl₂O₄, CuAl₂O₄, NiAl₂O₄, and ZnAl₂O₄ were successfully synthesized. The formation of Al₂O₃ NPs and MAl₂O₄ (M=Co, Cu, Ni, Zn) nanocomposite was confirmed by using several characteristics such as XRD, UV-Vis, FTIR, FE-SEM, and EDX spectra. The XRD shows that the CoAl₂O₄ has a smaller crystallite size (12.37 nm) than CuAl₂O_4, NiAl₂O₄, and ZnAl₂
