Abstract Kinetics of change in photoinduced currents (during illumination andafter switching off light source) in the solid state of some ferrocene derivatives,namely, ferrocenecarboxylic acid, acetylferrocene, ferrocenecarbaldehyde,hydroxymethyl ferrocene have been studied in dry nitrogen gas atmosphere. Unusual/anomalous photocurrent versus time profiles were observed in some ferrocenederivatives at certain cell temperatures. The kinetics of current changes underphotoexcitation and after switching off the light source have been observed to becomplicated in nature. Temperature-dependent behavior of the studied kineticsindicates that charge carrier trapping/ detrapping and recombination processes aresignificantly temperature dependent. These processes have an important role incausing the temperature dependent unusual/ anomalous photocurrent versus timeprofiles in the ferrocene derivatives studied.
