Highly Conductive Graphenated-Carbon Nanotubes Sheet with Graphene Foliates for Counter Electrode Application in Dye-Sensitized Solar Cells

This work enlightened the synthesis of graphenated-carbon nanotubes sheet (g-CNT) using floating-catalyst chemical vapor deposition method (FCCVD) for dye-sensitized solar cell (DSSC) application. The carbon injection flow rate in experiment was varied to 6, 8, and 10 ml/h. morphological findings revealed that g-CNT formed a highly conductive network. Excellent conductivity obtained sample g-CNT8 (34.5 S/cm) compared g-CNT6 (11.2S/cm) CNT10 (4.76 S/cm). excellent feature is due hybrid structure g-CNT8, which creates efficient electron transfer materials resulting higher conductivity. provides high surface area improves Therefore, an candidate replace conventional platinum used as counter electrode (CE) DSSC.
