✦ Synopsis

The performance of a Ru(II) dye-sensitized nanocrystalline TiO 2 solar cell (DSSC) with both Triton X-100 and water as additives in 3-methoxypropionitrile solutions is described. In the presence of these additives, the open-circuit voltage (V oc ), fill factor and stability of the cell increased, while the shortcircuit photocurrent density decreased compared to those found in their absence. Based on these changes, the DSSC yielded a higher solar-to-electricity conversion efficiency of 5.9%, compared to 5.3% for the cells fabricated without the additives. Furthermore, the addition of Triton X-100 to the water-added electrolyte was found to render the Ag metal corrosion resistant.

This study aimed to investigate the effect of pyridine in electrolyte on the photocurrent density-photovoltage (J-V) characteristics in dye-sensitized solar cells. When the concentration of pyridine (c p ) in an electrolyte (0.1 M LiI and 0.05 M I 2 in acetonitrile) is increased from 0 to 0.4 M, the
