Aqueous PEDOT:PSS Formulation

Used for applications in OPV and perovskite solar cells

HTL Solar (CAS number 155090-83-8) is an aqueous PEDOT:PSS formulation designed for use in thin film electronics as an interfacial material. The advantage of the HTL Solar formulation is its improved wetting properties, particularly in inverted OPV cells, compared to the other PEDOT:PSS formulations in our catalogue.

What is PEDOT:PSS? What is PEDOT:PSS?

PEDOT:PSS is a blend of two distinct polymers: poly(3,4-ethylenedioxythiophene) (PEDOT) and polystyrene sulfonate (PSS).

PEDOT and PEDOT:PSS Synthesis PEDOT and PEDOT:PSS Synthesis

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.
