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

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 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.

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.
