Photo-current in TIPS pentacene single crystals

Goal of this thesis is the study of the ultraviolet-visible photocurrent response in TIPS Pentacene single crystals, but also a description of the experimental method used to reach said objective. Emphasize is put on the approach utilized that this work imposed on us because of the challenges that arose. After preparing our organic semiconductor crystals, with the deposition of metal electrodes, our first measurement revealed that our initial experimental apparatus was not ideal to study the energy levels of a OSC, due to the slow and weak photocurrent response that many organic semiconductors have. A LabView program was therefore developed in order to aid us in the construction of the photocurrent spectrum of our TIPS Pentacene single crystals.
