Ossila HTL Solar (product code M124) is a water-based PEDOT:PSS formulation (CAS 155090-83-8) intended as an interfacial layer in thin film electronic devices. It is supplied as 100 ml of solution and is based on Clevios™ HTL Solar, with a PEDOT/PSS ratio of 1:2.5 w/w.
Its main benefit over other PEDOT:PSS grades is better wetting, which makes it well suited to inverted organic photovoltaic (OPV) cells and other thin films where coating coverage is a problem. It can be used in OPV, OLED and perovskite solar cell structures.
The formulation offers relatively high conductivity of 0.1 – 1.0 S/cm, a work function of 4.8 – 5.0 eV and a viscosity of 8 – 30 mPa.s, with a solid content of 1.0 – 1.3 wt.%. HTL Solar from Ossila has been used in published research, including work in Nature Communications and Nano Energy.
- Hole transport or interfacial layer in inverted organic photovoltaic (OPV) cells.
- Interfacial layer in perovskite solar cells.
- Thin film layer in OLED devices.
- Coating thin films that are difficult to wet with standard PEDOT:PSS formulations.
- Spin-coated thin film deposition in thin film electronics research.
