Synthesis of SrTiO3/rGO Photocatalyst for use in Dye Sensitized Solar Cell (DSSC)
, M.Sc. Thesis Sharif University of Technology ; Mohammadi, Mohammad Reza (Supervisor)
Abstract
The objective of this research was to fabricate nanocomposites based on reduced graphene oxide (rGO) and strontium titanate (SrTiO₃) and investigate their photovoltaic properties as charge transport platforms in dye-sensitized solar cells (DSSCs). Initially, graphene oxide was prepared using the Hummers method and combined with strontium titanate through a ex-situ approach. Subsequently, strontium titanate based on reduced graphene oxide nanocomposites were obtained using thermal and solvothermal methods. Structural and optical characterization of these nanocomposites was performed using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, thermogravimetric...
