General description

Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) (dry re-dispersible pellets) is a conductive polymer that is formed by electropolymerizing 3,4-ethylenedioxythiophene in a solution of poly(styrenesulfonate)(PSS). PEDOT is doped with positive ions and PSS with negative ions. It has the following properties that make it viable polymer in organic electronics:
  • low band gap
  • good optical properties
  • high conductivity
  • low redox potential
  • easy processing
  • tunable film forming ability

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This product is used in energy conversion and storage, thus has been enhanced for energy efficiency. Click here for more information.

Application

Orgacon™ DRY5 pellets can be re-dispersed in organic solvents such as ethanol. The resulting dispersion can be used in coating or ink formulations targeted for different applications requiring high conductivity.
PEDOT:PSS can be used as an electrode material with high mobility for charge carriers. It can be used for a wide range of energy based applications such as organic photovoltaics (OPV), dye sensitized solar cells (DSSCs), organic light emitting diodes (OLEDs), supercapacitors and other biomedical based sensors.
PEDOT:PSS can be used as the active semiconductor layer in OFETs. It is commonly used as a hole transport layer in OPVs.
Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.
