This research investigated urea and reduced graphene oxide (rGO) as potential additives to a dye-sensitized solar cell (DSSC) iodide/triode electrolyte, in order to enhance overall electrical performance. Additive concentrations of 0, 2, 5, 10, and 15 wt% were investigated. In general, both additives were found to enhance DSSC electrical performance with respect to open circuit voltage Voc and DSSC fill factor FF. The greatest enhancement in these parameters occurred at an additive concentration of 10 wt%. Urea produced a greater degree of enhancement than rGO; the overall efficiency was increased by 10.17±0.01% for urea vs 9.57±0.01% for rGO. The specific mechanisms by which performance was increased differed between the additives. This degree of performance enhancement may be near the limits of what is achievable given current DSSC technology and development.
