Popular Aqueous PEDOT:PSS Formulation

Used for applications in OPV, OLED, perovskite solar cells, and lighting

| |

P VP AI 4083 (CAS number 155090-83-8) is one of the most commonly used aqueous formulations. Due to its deep work function it is often used for the matching of interfacial energy levels in thin film electronic devices. With a PEDOT:PSS ratio of 1:6, AI 4083 has low conductivity with relatively high resistance of 500 to 5000 Ω.cm. It has been widely used in organic and inverted PSCs and OLEDs as a hole transport material.

Resources and Support

For the deposition of thin films of PEDOT:PSS on a freshly prepared surface, we recommend using a vacuum-free spin coater and following this five-step process:

PEDOT synthesis involves the oxidative chemical or electrochemical polymerization of EDOT monomer. The choice of counterions and polymerization method significantly affects the conductivity, work function, and stability of the resulting PEDOT polymer.
