Abstract:
Recently, dye-sensitized solar cells have proven to be one of the preferable technologies because of their ease of fabrication and cost effectiveness. But DSSC suffered from problem of low conversion efficiency in comparison to conventional solar cells. Conversion efficiency can be enhanced by increasing the absorption coefficient of photoabsorbing layer. Much effort has been done to synthesize the dyes of higher absorption coefficient. A complementary approach is to trap the light using surface plasmon resonance of metal nanoparticles. But bare metal nanoparticles being in direct contact with dye and electrolyte leads to the recombination of photogenerated carriers which further puts a limit on the efficiency enhancement of DSSC via plasmonic property of metal nanoparticles. Keeping these reports into consideration, we have focused our work on the preparation and characterization of surfactant capped silver nanoparticles by chemical reduction method to develop improved plasmonic DSSC. SPR band of silver nanoparticles has been confirmed by UV-Vis spectroscopy. FTIR confirms the capping of CTAB on silver nanoparticles occurs via their head group. Finally, these particles have been incorporated in DSSC to study the plasmonic effect of nanoparticles on performance of DSSC. The power conversion efficiency of DSSC and the plasmonic DSSC were found to be 4.3 % and 5.38%, showing an improvement of 25.11%
