High Conductivity PEDOT:PSS Formulation
Used for applications in OPV, OLED, and perovskite solar cells
Clevios™ PH 1000 PEDOT:PSS (CAS number 155090-83-8) is designed for applications where high conductivity and optical transparency are required. The potential uses for high conductivity PEDOT:PSS formulations include replacements for ITO, semitransparent top electrodes in thin film electronics, top gate electrodes in FETs, and for use as a thick planarization layer on rough surfaces such as FTO. Sheet resistances as low as 300 Ω/square can be achieved with the addition of conductivity enhancement agents such as dimethyl sulfoxide and ethylene glycol.
PEDOT:PSS (PH 1000) from Ossila was featured in the high-impact paper (IF 30.85), A Wearable Supercapacitor Based on Conductive PEDOT:PSS-Coated Cloth and a Sweat Electrolyte, L.

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.
