Abstract

This study investigates the effect of variation of electrolyte on the output performance of A.cepa peel dye-sensitized solar cells. Four A.cepa dye-sensitized solar cells were sensitized with different liquid electrolytes. The criteria used for assessing their performance was the short circuit current (Isc), open circuit voltage (Voc), maximum power (Pmax), fill factor (ff), output efficiency (ƞ) and the incident photon to conversion efficiency (IPCE). The responses produced by the A.cepa dye solar cells were varied. The most efficient electrolyte was Mercury chloride (HgCl2) with an efficiency of 0.27%, potassium bromide (KBr) recorded the highest value in maximum power (Pmax), fill factor (ff) and open circuit voltage (Voc) with the following values: 38.09 W, 2.83 and 700 V respectively. HgCl2 also had the highest Isc, with a value of 0.04 mA and the best IPCE was obtained with KCl with a value of 1.64%. The significance of this outcome is that, HgCl2 and KCl electrolytes influenced the performance of A.cepa peel dye-sensitized solar cell by suppressing dye agglutination while KBr electrolyte improved A.cepa peel dye-sensitized solar cell’s electrochemical stability.
