Abstract

To improve the conversion efficiency of dye-sensitized solar cell, the cell was fabricated employing silver nanoparticles doped photoanode. The nanoparticles of silver were produced using the pulsed laser ablation technique. The I-V characteristics and impedance spectroscopic measurements were performed on the doped and undoped photoanode based devices under simulated AM 1.5 illumination (100 mWcm−2 ) and dark, respectively. The nanoparticles doped photoanode based plasmonic DSSC exhibited about 46.3 % higher efficiency than the reference cell. This boosted performance of the plasmonic DSSC can be attributed to enhanced interfacial charge transfer, decrease of charge recombination, decrease of series resistance and plasmonic enhanced absorption of radiation by the dye. The impedance spectra also revealed higher photovoltaic performance of the plasmonic cell..
