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.
