High Conductivity PEDOT:PSS Formulation

Used for applications in OPV, OLED, and perovskite solar cells


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, semi-transparent 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.
