Abstract
We have fabricated vanadium carbide counter electrode (CE), and we have investigated suitable binder combination (conductive carbon/N-methyl pyrrolidone (CC/NMP), NMP, CC/IPA (isopropanol)) material for increasing bonding strength, crack-free coated films, high conductivity and highly catalytic activity functions on the fluorine-doped tin oxide (FTO) glass substrate for the redox reaction at the counter electrode of dye-sensitized solar cells (DSSCs). The power conversion efficiency of 3.9% is obtained for vanadium carbide–CC/NMP binder, comparable performance to the traditional Pt-based CE (4.0%). Based on the electrochemical investigation and current–voltage measurement, the comparable efficiency was achieved by the higher current density (J sc) and lower charge transfer resistance (R ct) due to the CC/NMP binder which is increasing bonding strength between CE materials and FTO. The present investigations open promising ways to the further movement for substantial amount of production of traditional Pt-free DSSC.
