  Abstract:  The goal of our research is to investigate the coupling of gold nanoparticles (GNP) with porphyrins molecules. Our work reported here has revealed that a strong and large absorption band is obtained when a complex between gold nanoparticles (GNP) and porphyrin dye is formed. The exchange of the initial ligand (citrate ions) with porphyrins formed hybrid nanostructures and change the electronic properties of GNP. Porphyrins could be used for designing dye sensitized solar cells. The correlation between their band gap HOMO-LUMO and the conduction band of the semiconductor (TiO2) allow the electron transfer from the dye to the electrode, through the semiconductor.
