Implementation of 12nm Graphene Flakes in TiO2/G Composite for High Power Conversion in DSSCs: *Note: Sub-titles are not captured in Xplore and should not be used

Due to its high electron mobility, chemical characteristics, low cost, and environmental friendliness, graphene is a promising material and alternative way for achieving high performance in dye-sensitized solar cells (DSSCs). It is zero electron-volt energy bandgap allows it to improve electron transport efficiency and light absorption. The TiO 2 /G composite was synthesized by using the TiO 2 process methodology. The different quantities of graphene flakes were applied and photovoltaic performance, internal impedance, and absorbance were determined. As a consequence, this graphene doping enhanced overall performance increased by 11.41% of its efficiency for a thickness of $13\mu \mathrm{m}$ compared with pure TiO 2 .
