%X The tungsten sulfide/multi-wall carbon nanotube (WS2/MWCNT) hybrid was prepared in the presence of glucose by
the hydrothermal route. The hybrid materials were used as counter
electrode in the dye-sensitized solar cell (DSSC). The results of
cyclic voltammetry measurement and electrochemical impedance spectroscopy
indicated that the glucose aided prepared (G-A) WS2/MWCNT
electrode had low charge-transfer resistance (Rct) and high electrocatalytic activity for triiodide reduction.
The excellent electrochemical properties for (G-A) WS2/MWCNT
electrode is due to the synergistic effects of WS2 and
MWCNTs, as well as amorphous carbon introduced by glucose. The DSSC
based on the G-A WS2/MWCNT counter electrode achieved a
high power conversion efficiency of 7.36%, which is comparable with
the performance of the DSSC using Pt counter electrode (7.54%).
