This study investigated the different thicknesses of TiO2 photoanode films and the effect of surface plasmon resonance (SPR) of Ag-TiO2 nanocomposites on the current-voltage (I–V) performance of dye-sensitized solar cells (DSSC). The TiO2 layer was deposited using the doctor blade technique and the thickness of the TiO2 films was controlled by using a different number of Scotch tape layers. The silver nanoparticles (AgNP) were synthesised using a chemical reduction method and the concentration of sodium citrate as a reducing agent was varied from 4 to 12 mM to study the effect of citrate ion on the size of the nanoparticles. Ag-TiO2 nanopowder was prepared by adding pure anatase TiO2 powder into AgNP colloidal solution. The mixture was left to dry for 24 h to obtain Ag-TiO2 powder for paste preparation. The three-layer Scotch tape, with thickness of 14.38 µm, achieved a high efficiency of 4.14%. This results showed that three layers was the optimal thickness to improve dye loading and to reduce the charge recombination rate. As for the Ag-TiO2 nanocomposites, 10 mM of AgNP, with a mean diameter of 65.23 nm and high efficiency of 6.92%, proved that SPR can enhance the absorption capability of dye and improve the photon-to-electron generation.

We demonstrate a strategy for incorporating plasmon resonant metallic nanoparticles in the construction of the three-dimensional (3D) interwoven structured TiO 2 photoanodes. The 3D interwoven structure contained continuous TiO 2 skeleton and numerous interconnected macro/mesopores, which supplied effective straight path for electron transfer and high specific surface area for dye load. Localized surface plasmon resonance (SPR) was produced by the addition of gold nanoparticles ( AuNPs ), which increased the light absorption of the photoanodes more effectively. The synergistic effect of SPR with constructed TiO 2 nanostructures has been investigated, and was confirmed by field-emission scanning electron microscope (FESEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), UV-Vis absorption spectra, J–V characteristics, and electrochemical impedance spectroscopy (EIS) analysis. It was found that the range and strength of light absorption of TiO 2 photoanodes, the photon capture ability of the dye molecules, the photoelectric conversion efficiency were significantly increased while the electron transfer resistance decreased due to the incorporation of AuNPs compared to the P25 and Au -free photoanode. The related photoelectric performance enhancement mechanisms, and surface-plasmon resonances in dye-sensitized solar cells (DSSCs) with Au nanostructures were analyzed and discussed.
