Paper Abstract

The dramatically reduction of cost of photodetectors without comprising their performance will enable new applications in many fields. In this talk, I will brief our progress in the development of sensitive photodetectors/photon counters using low-cost solution processable organic and nano-electronic materials. Four types of device structures will be compared in terms of device gain, noise, sensitivity, response speed and linear dynamic range: 1) traditional diode structure, 2) a structure combine the photodiode and photoconductor through the interface trap triggered secondary charge injection, 3) an organic phototransistor that has combined photoconductive gain and photovoltaic gain, and 4) quantum dots modulated transistor channel conductance. Broad response spectrum from UV to NIR will be demonstrated, and active material limited performance will be discussed.
