Firstly, CdO thin film was grown on a conductive layer (ITO) using the electrochemical deposition method. Then, coronene organic semiconductor was grown on CdO thin film using thermal evaporation method and coronene/CdO hybrid heterojunction was produced. The optical analysis of the fabricated heterojunction was examined in the wavelength range of 300-850 nm, and optical parameters were determined. It was observed that the the absorption coefficient (alpha) value of the heterojunction was in the order of approximate to 10(6) m(-1) and the Eg value (2.01 eV) was in the visible region. The diode parameters of the coronene/CdO hybrid heterojunction which showed negative differential resistance (NDR) effect behavior were determined, and it was observed that the ideality factor value was 7.58, the series resistance value was approximate to 10(3) omega, the shunt resistance value was approximate to 10(5) omega, the barrier height value was approximate to 0.3 eV, and the reverse saturation current value was approximate to 10(-8) A. The photodetector and photovoltaic characterization of the coronene/CdO hybrid heterojunction at different light intensity values was investigated under +/- 0.1 V and with zero bias. It is observed that it exhibited self-powered diode behavior under zero bias and the heterojunction was light-sensitive. The determined maximum photocurrent (Iph), responsivity (R), sensitivity and specific detectivity (D*) values were found to be 2.03 x 10(-7) A, 1.53 x 10(-2) A.W-1, 7.44 x 10(-8) S.m.W-1 and 9.94 x 10(9) Jones, respectively. In addition, the Isc and Voc values increased with the increase in the light intensity and the maximum FF% value was 31.14%.eninfo:eu-repo/semantics/closedAccessArticle
