Synthesis of CoSe2/RGO Composites and Their Application in a Counter Electrode of Dye-sensitized Solar Cells |
| 초록 |
In this study, cobalt diselenide (CoSe2) and the composites of CoSe2 and reduced graphene oxide (CoSe2@RGO) were synthesized by a facile hydrothermal reaction of cobalt ions and selenide source with or without graphene oxide for a cost-effective counter electrode material of DSSCs instead of Pt. Electrochemical analyses such as electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) showed that CoSe2@RGO composites have excellent catalytic activity for reduction of I3- exhibiting synergetic effect between CoSe2 and RGO. As a consequence, the DSSC using the CoSe2@RGO CE exhibited the comparable power conversion efficiency (7.01 %) to the Pt-based CE device (6.77 %). |
