Abstract
Light absorption by photovoltaic (PV) devices is shown to improve with the use of plasmonic silver nanoparticles (100 nm size) added to the active layer of dye-sensitized solar cell (DSSCs). The electrolyte containing 2 wt.% silver nanoparticles exhibits the highest conductivity of 1.27 x 10(-2) S cm(-1). The DSSC using this electrolyte exhibits the highest efficiency of (6.99 +/- 0.15) %. The J(sc) is (14.25 +/- 0.71) mA cm(-2), V-oc is (0.70 +/- 0.01) V and FF is (69.94 +/- 3.80) %. The same DSSC also exhibits the shortest electron transport time, tau(tr) of (7.00 +/- 0.41) ms and long recombination time, tau(rec) of (87.22 +/- 9.17) ms.
