Implementation of 12nm Graphene Flakes in TiO2/G Composite for High Power Conversion in DSSCs

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
