Infrared Detectors with Poly(3,4‐ethylenedioxy thiophene)/Poly(styrene sulfonic acid) (PEDOT/PSS) as the Active Material

Abstract

Fast‐response large‐area plastic infrared detectors (see Figure (Wheatstone bridge configuration)) made from a conducting PEDOT/PSS film achieve a detectivity close to 10 5 cm √Hz W –1 at 1.18 eV. The nanosecond response arises from the direct absorption of infrared light by the charge carriers on the polymer chain. The recovery of the device after illumination is much slower and is governed by heat transport from the polymer.
