| Summary: | 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 × 10−2 S cm−1. The DSSC using this electrolyte exhibits the highest efficiency of (6.99 ± 0.15) . The Jsc is (14.25 ± 0.71) mA cm−2, Voc is (0.70 ± 0.01) V and FF is (69.94 ± 3.80) . The same DSSC also exhibits the shortest electron transport time, τtr of (7.00 ± 0.41) ms and long recombination time, τrec of (87.22 ± 9.17) ms.
