Popular Aqueous PEDOT:PSS Formulation
Used for applications in OPV, OLED, perovskite solar cells, and lighting
Clevios™ P VP AI 4083 (CAS number 155090-83-8) is one of the most commonly used aqueous PEDOT:PSS 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.
PEDOT:PSS (AI 4083) from Ossila was featured in the high-impact paper (IF 56.7), Scalable two-terminal all-perovskite tandem solar modules with a 19.1% efficiency, B. Nejand et al., Nat. Energy, 7, 620–630 (2022): DOI: 10.1038/s41560-022-01059-w; and paper (IF 9.5), Benzophenone: A Small Molecule Additive for Enhanced Performance and Stability of Inverted Perovskite Solar Cells, H. Elbohy et al., ACS Appl. Mater. Interfaces, 15 (38), 45177–45189 (2023); DOI: 10.1021/acsami.3c09835.

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.
