Abstract

In order to study the hole transport in chlorophyll a (Chl a), time-of-flight measurements have been performed on Al/Chl a/Au sandwich cells. The hole transients are almost featureless and the transit times have been determined from log-current-log time plots. In view of the lack of universality in post-transit region and the tendency of mobility to decrease with increasing field, as observed from log μ vs E plots, the hole transport in Chl a has been described in terms of charge transport based on the disorder formalism of Bässler and co-workers. The decrease of hole mobility with field suggests a strong involvement of off-diagonal disorder.
