Ossila PH 1000 PEDOT:PSS is a water-based dispersion of Clevios™ PH 1000 (CAS 155090-83-8), a conductive polymer formulation chosen where a film must be both highly conductive and optically transparent. It is widely used to build interfacial and electrode layers in organic photovoltaics, OLEDs and perovskite solar cells.
The formulation combines PEDOT and PSS in a 1:2.5 w/w ratio at a solid content of 1.0 – 1.3 wt.%, with a work function of 4.8 – 5.0 eV and a median particle size (D50) of 30 nm. Adding conductivity enhancers such as dimethyl sulfoxide or ethylene glycol raises performance considerably: with 5% dimethyl sulfoxide, dried coatings reach 850 S/cm, and sheet resistances as low as 300 Ω/square are possible.
Ossila's PH 1000 has appeared in published research, including work on a wearable supercapacitor built from PEDOT:PSS-coated cloth (Adv. Mater., 2020) and an electro-active metaobjective (Nat. Commun., 2022).
- Replacing ITO as a transparent conductive electrode.
- Forming semi-transparent top electrodes in thin film electronic devices.
- Serving as top gate electrodes in field-effect transistors (FETs).
- Depositing a thick planarization layer over rough surfaces such as FTO.
- Building interfacial layers in OPV, OLED and perovskite solar cells.
