Abstract
- A low-cost and efficient MoS 2 /graphite paper (GP) counter electrode for dye-sensitized solar cells (DSSCs) is first fabricated by a simple and effective solution processed route. Photo-electric conversion efficiency of 6.48% is obtained for the DSSC adopting MoS 2 /GP, better than the device (6.22%) employing platinized F-doped tin oxide (Pt/FTO) electrode. Because highly conductive GP is performed as a substrate, and the mechanical adhesion and electrical connection between the MoS 2 film and the GP substrate are strong, the series resistance of MoS 2 /GP is much smaller than that of Pt/FTO. A comparable charge transfer resistance of MoS 2 /GP to Pt/FTO is found to be another factor for the better performance. Due to the MoS 2 prepared here possessing relatively high crystallinity and firmly being anchored on the GP substrate, MoS 2 /GP as well exhibits high stability. Hence, excellent electrochemical activity, high stability, facile preparation and low material cost of the MoS 2 /GP electrode offer it a promising potential for large-scale production.
