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 high-temperature 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.
