Abstract
Time resolved photoconductivity measurements are reported for pulsed excitation of highly oriented poly(p-phenylene-vinylene) [PPV] films. These measurements reveal a large, short lived photoconductive conductive response separate from the long lived component that has been investigated by several other groups. We report the dependence of this short lived photocurrent upon energy and intensity of the excitation light and upon the magnitude and orientation of the applied DC bias field for both fully and partially converted PPV-films.
