Abstract
Photoconductivity experiments using steady illumination with visible l ight have been carried out with emeraldine base to estimate the mobili ty of the photoexcited charge carrier. The results are compared with t he earlier transient photoconductivity measurements. The low value for mobility of 3.5 X 10(-5) cm2/VS obtained is ascribed to bipolaron for mation. Photoelectrochemical measurements of charge decay with emerald ine salt electrode are also reported and compared with the above value s.
