Nanocarbon counterelectrode for dye sensitized solar cells
- Electric and Magnetic Devices Research Group, Korea Electrotechnology Research Institute, Changwon 641-120 (Korea, Republic of)
Nanosize carbon powders were deposited on conducting glass substrate for counterelectrode application in dye sensitized solar cell (DSSC). Electrochemical impedance measurement shows that charge transfer resistance of carbon electrode in liquid electrolyte is 0.74 {omega} cm{sup -2}, which is two times less than that of screen printed platinum. Using such counterelectrode and dye sensitized TiO{sub 2} working electrode, DSSC was fabricated. Under one sun illumination (AM1.5, P{sub in} of 100 mW cm{sup -2}), carbon counterelectrode DSSC shows 6.73% overall energy conversion efficiency with good stability.
