Inkjet printing of conducting polymers for optoelectronic devices - processability and wetting characteristics

                        DST funded project: Summary

Abstract of the proposed work: World over, inkjet printing has emerged as
an appealing patterning technique for conducting polymers used in
opto-electronic devices such as light-emitting diodes (LEDs),
photo-voltaic devices and polymer thin-film transistors PTFTs. The study
also aims looking into the wetting characteristics of different conducting
polymer dispersions on different substrates and how it gets altered by
various additives and external field conditions. The rheological and
wetting characteristics will be used for arriving at optimum/best possible
processing conditions which can be used for inkjet printing of
devices.Polymeric photovoltaic (PV) and LED device will be fabricated
using this information and will be compared with devices fabricated using
other methods like solvent casting and spin coating for its performance.
