Performance of Photoelectrochemical Sensors Based on Doped QDs under Various Bias Voltage

Abstract

In this paper, a novel photoelectrochemical sensor based on doped quantum dots (QDs) under various bias voltages was designed, first, photoelectrochemical sensors were designed for detection of chemical solution concentration. Second, the fabrication processes of doped QDs based sensors were described, third, doped QDs based sensors were tested under different applied potentials and light sources to show different measurement characteristics. From the experimental results, it can be concluded that the doped QDs based sensors designed under-300mV applied potential and 365nm light source show the best performance.
