Abstract
Nanosize carbonpowders were deposited on conducting glass substrate for counterelectrode application in dye sensitized solar cell(DSSC). Electrochemical impedance measurement shows that charge transferresistance of carbonelectrode in liquid electrolyte is 0.74 Ω cm − 2 , which is two times less than that of screen printed platinum. Using such counterelectrode and dye sensitized Ti O 2 working electrode,DSSC was fabricated. Under one sun illumination (AM1.5, P in of 100 mW cm − 2 ), carbon counterelectrode DSSC shows 6.73% overall energy conversion efficiency with good stability.Keywords
