Abstract (EN)
In this study, electrical and optical properties of Al/Polymer/PEDOT-PSS/ITO heterojunction structure have been investigated. Optical properties of the obtained poly(pentachlorophenly methacrylate) insolution were tested by ultraviolet-visible (UV-Vis) absorption spectroscopy. Direct and indirect optical band gap of polymer have been calculated by UV-Vis measurements as 4,96 eV and 4,76 eV respectively. The electrical properties of a spin-coated Al/polymer/PEDOT-PSS/ITO heterojunction structure has been investigated by current-voltage (I-V) measurements at room temperature. The main electrical parameters such as barrier height ?BO, ideality factor n and reverse saturation current Io have been calculated by applying thermionic emission theory as 0,634 eV, 4.26, 1,21x10-6 A respectively. Additionaly, series resistance Rs, ?BO and n were calculated from the forward bias I-V data using the methods of Cheung and Cheung with Norde and showed that these methods can be applied succesfully for this structure.
