Nanostructured PEDOT: PSS /ZnO Heterojunction Diodes as Ultraviolet Sensors

Development in ultraviolet (UV) photodetectors get research community attention and incorporated in a wide range of applications. To improve light sensitivity, wideband gap nanotechnology was employed, such as zinc oxide for its notable properties. The vital role is on UV heterojunctibility sensing between ZnO NPs and polymer conducting nanocomposites (3, 4-ethylenedioxythiophene), poly (styrenesulfonic acid) (PEDOT: PSS). the photovoltaic effect was observed, characterized, and examined at a wavelength of 365 nm. ZnO NPs are coated with an indium tin oxide painted with glass at the top of the (PEDOT: PSS) layer. Then, aluminum is deposited on the top of the unit electrode. The current-voltage function exhibits the appropriate behavior in the dark field. With ultraviolet light, the backward orientation of current has been detected, as well as the forward orientation. Current-voltage data reveal that the barrier voltage drops down when exposed to UV light.
