Abstract: (818 Views)
The aim of this study is the synthesis and utilization of a nanostructure based on graphene and gold in the photoanode of dye sensitized solar cell. The plasmonic properties of gold nanoparticles increase the absorption of the visible region. On the other hand, graphene oxide with its efficient properties such as high transparency in the visible region, low resistance to electron transfer, stability and high specific surface area can be used in the electron transfer layer and photoanode of the cell, which here an optimal nanocomposite was made for photoanode of dye solar cell with applying an appropriate synthesis method and proper bonding of gold nanoparticles to graphene plates. In addition, the use of gold nanoparticles with a very small size of 2 nm in the dye solution was able to increase the absorption in the dye. The reason for choosing a small size is that the nanoparticles do not interfere with the adsorption of dye on the surface of TiO2.
