Abstract

Mesocellular carbon foams (MSU-F-Cs) with a high surface area (911 m2g-1) and large pores (~ 25 nm) have been used as counter electrodes for CdS/CdSe quantum-dot sensitized solar cells (QD-SSCs). Under 1 sun illumination, the MSU-F-C counter electrode QD-SSC shows a maximum energy conversion efficiency of 1.75%, which is much higher than that of those employing conventional Pt (1.22%) or commercial carbon (0.94%) counter electrodes. Electrochemical impedance spectroscopy analysis shows that the large pores and high surface area of MSU-FC improve the catalytic activity of the counter electrode in polysulfide redox electrolyte.
