Abstract:

In this research, the synthesis of plasmonic nanoparticles was carried out by chemical dissolution method in three steps. Then, Au@TiO2 and Au@SiO2 core-shell nanostructures have been investigated. These nanostructures were used as photoanode in dye-sensitized solar cells (DSSCs). Parameters such as short circuit current, open circuit voltage, fill factor and conversion efficiency of DSSCs were obtained. The cell in which Au@TiO2 synthesized with mercaptoacetic acid ligand is used, has the highest efficiency. The primary causes of this are the heightened near-field effect of gold nanoparticles (AuNP) and the creation of enhanced photocurrent due to plasmonics.
