The current-voltage and capacitance-voltage characteristics of Al/20D-TIFDKT/p-Si/Al devices with aluminized contacts were investigated under dark and 100 mW/cm(2) illumination intensity. The result is a novel interface-state controlled diode device that is shown to be rectifying. In the forward, bias it has a current that depends on the illumination intensity at constant bias, showing potential application in low-power solar cell application. In the reverse bias, it has a response that depends on the illumination intensity regardless of the applied reverse bias. This suggests a potential use as a sensor in photoconductive applications. Between 0 and 0.7 V forward bias, the ideality factor, series resistance and barrier height average at 2.35, 67.6 k Omega and 0.842 eV, respectively, regardless of illumination  ISSN : 0379-6779  Journal Name : SYNTHETIC METALS  Volume : 221  Issue Number : 1  Publishing Year : 1437 AH 2016 AD  Article Type : Article  Added Date : Tuesday, August 8, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email r.o Ocaya Ocaya, r.o Investigator Doctorate   Mehmet Ozdemir Ozdemir, Mehmet Researcher Doctorate   Resul Ozdemir Ozdemir, Resul Researcher Doctorate   A.A Al-Ghamdi, Al-Ghamdi, A.A Researcher Doctorate   Hakan Usta Usta, Hakan Researcher Doctorate   W.
