Comparison Study of Metal Oxides (CeO2, CuO, SnO2, CdO, ZnO and TiO2) Decked Few Layered Graphene Nanocomposites for Dye-Sensitized Solar Cells

Recent research is focused on few layered graphene (FLG) with various metal oxides (MOs) as (MOs; CeO2, CuO, SnO2, CdO, ZnO, and TiO2) nanocomposite materials are alternatives to critically important in the fabrication of solar cell devices. In this work, FLG different MOs nanocomposites were prepared by a novel eco-friendly viable ultrasonic assisted route (UAR). The FLG/MO performed characterization techniques. crystal phase compositional carried out through using X-ray diffraction technique. Surface morphological studies field emission scanning electron microscope (FE-SEM) high-resolution transmission microscopy (HR-TEM). Spectroscopic methods done Raman UV-Vis Diffuse reflectance spectra (UV-DRS). used photoanode, dye sensitized cells (DSSCs). Compared TiO2 nanoparticles (NPs) other nanocomposites, FLG/TiO2 exhibited superior photovoltaic properties. obtained results indicate that significantly improved power conversion efficiency (PCE) DSSCs. analyses simulator an air mass (AM) 1.5 G, density 100 m W/m2, current density-voltage (J-V) was investigated N719 dye.
