Semiconducting-polymer-based position-sensitive detectors

We demonstrate the utility of the organic semiconducting polymers as active media for light-sensitive position-sensitive detectors (PSDs). The characteristics of these PSDs include reasonable linearity and photoresponsivity over a large range of distance, photovoltaic mode of operation, and other ad...

description We demonstrate the utility of the organic semiconducting polymers as active media for light-sensitive position-sensitive detectors (PSDs). The characteristics of these PSDs include reasonable linearity and photoresponsivity over a large range of distance, photovoltaic mode of operation, and other advantages such as nonrigid substrates and absence of any other transporting-conducting coating layer. These devices utilize the formation of Al-polymer Schottky-type photoactive interface as a common backcontact. We demonstrate results for poly(3-hexylthiophene)-based PSDs of different interelectrode spacings where the photovoltaic signals as a function of incident-beam position are linear over the entire range.
