Abstract

Our work deals with dynamic response of semitransparent organic photodetectors over a large frequency range for high and low light illumination intensities through performing a detailed transient response of the device at pulsed photoexcitation of green emission. We present systematic simulation based on drift diffusion approach to analyzing the effect of unbalance charge carrier mobility and non-uniform absorption of thin film organic photodetector on dynamic response of the device. Our result suggests engineering of the interface layers is critical to achieve high performance device for high-speed applications.
