Characteristics of Ultraviolet Sensor Based on PEDOT:PSS/Al Doped ZnO Film

Abstract

Ultraviolet (UV) sensors have application in many different areas such as flame and hightemperature detection, space research, environmental monitoring, ozone layer monitoring, and missile warning systems. Among them, ZnO thin-film-based UV sensors have been attracting attention among research groups and are being continuously studied. The incorporation of ZnO/organic hybrid structures into solar cells and other photoelectrochemical applications has been extensively reported. However, little research has been performed on ZnO/polymer-based UV sensors. In this study, a simple UV sensor based on an Al:ZnO/polymer is demonstrated. Al-doped ZnO enables effective UV detection with excellent performance at low operating voltages using a simple and inexpensive process.
