HTL Solar 3 PEDOT Complex
Toulene-Based PEDOT Formulation
Used for applications in OPV and perovskite solar cells
The future production of HTL Solar 3 PEDOT Complex has been discontinued. We can only supply HTL Solar 3 PEDOT Complex as long as stock lasts. It will be replaced by HTL Solar 4 PEDOT (M1214) Complex in anisole as an alternative with similar properties.
HTL Solar 3 PEDOT Complex is a toulene-based PEDOT formulation using an alternative counter ionomer to PSS, allowing for the dispersion in toluene. HTL Solar 3 is ideal for use with materials, or in environments, that are water sensitive. Examples include in glove box environments or for use with perovskite inks or perovskite precursor materials.
PEDOT Complex (HTL Solar 3) from Ossila was featured in the high-impact paper (IF 39.8), Efficient, stable, and fully printed carbon-electrode perovskite solar cells enabled by hole-transporting bilayers, T. Du et al., Joule, 7 (8), 1920-1937 (2023); DOI: 10.1016/j.joule.2023.06.005; and paper (IF 22.0), Carbazole-Based Hole Transport Polymer for Methylammonium-Free Tin–Lead Perovskite Solar Cells with Enhanced Efficiency and Stability, J. Wang et al., ACS Energy Lett., 7 (10), 3353–3361 (2022); DOI: 10.1021/acsenergylett.2c01578.

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 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.
