Anisole-Based PEDOT Formulation

Used as hole transport layer for applications in OPV and perovskite solar cells

As an alternative to HTL Solar 3 (M125), HTL Solar 4 PEDOT Complex is another organic solvent based PEDOT formulation based in higher boiling point solvent anisole (CH3OC6H5) using an alternative counter ionomer to PSS. Anisole, titled as methoxybenzene, has a distinctive smell reminiscent of anise seed with a boiling point of 154 °C. It is a non-halogenated solvent that can promote highly crystalline semiconductor thin films with longer drying times.

Applicable in both standard and inverted type organic solar cell architectures, anisole based HTL Solar 4 exhibits good wetting and coating properties on most active layer materials, i.e. perovskite and polymer solar cells. HTL Solar 4 serves as hole transport interlayer (HTL) material between the active layer and electrode.

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.
