Anisole-Based PEDOT Formulation
Used as hole transport layer (HTL) for applications in OPV and perovskite solar cells.
| |
As an alternative to , HTL Solar 4 PEDOT Complex is another option for use as a hole transport layer in photovoltaics. The 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.
Stored at dark cool dry place with temperature not exceeding 40 °C, do not refrigerate.

Resources and Support
For the deposition of thin films of PEDOT materials 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.
