Hello Azeez,

In my knowledge, PEDOT:PSS is a transparent conducting polymer, and frequently used as a hole injection layer in LED fabrication.

Dear M S Abdul Azeez ,

PEDOT:PSS is a p type high conductivity polymer mixer semiconductor. It has applications in semiconductor devices where it functions as a hole transport layer in organic solar cells and hole injector in LEDs.

Best wishes

Following the above researchers comments, there are several types of PEDOT:PSS solutions according to their conductivities. In general, PEDOT:PSS is a mixture of ionomers. According to their ratio of the mixture, the conductivity is different. Although the commercial products of PEDOT:PSS also have additional dopants to satisfy different purposes of the applications. For example, OLEDs, solar cells, anti-statics and capacitors.

Hi M S Abdul Azeez, thanks for your question. The materials do not exhibit a direct-current conductivity are dielectrics.
