Abstract

We report fabrication and characterization of an organic photodetector (OPD) in the form of ITO coated glass/Polycarbazole (PCz)/Al Schottky contact for application in visible region and Al/PANA/ITO, Ti/PANA/ITO Schottky contacts of application in U.V. region. The current voltage (I-V) characteristics of the devices were measured by using microprobe arrangement. The performance parameters of ITO/Polycarbazole (PCz)/Al Schottky contact have been compared and contrasted with those of ITO/PANA/Al and ITO/PANA/Ti Schottky contacts. UV-Vis spectroscopic measurement revealed strong absorption spectra of the two types of devices in the visible and U.V. region respectively.
