Ossila PEDOT:PSS AI 4083 (Clevios™ P VP AI 4083, CAS 155090-83-8) is a water-based PEDOT:PSS dispersion widely chosen as a hole transport layer in thin film electronics, including organic photovoltaics, OLEDs, lighting and perovskite solar cells.
Its deep work function of 5.0 – 5.2 eV makes it well suited to aligning interfacial energy levels between device layers. The formulation uses a PEDOT to PSS ratio of 1:6 by weight, which gives deliberately low conductivity (0.0002 – 0.002 S/cm) and a resistivity in the range of 500 – 5000 Ω.cm. It has seen broad use in organic and inverted perovskite solar cells as well as OLEDs.
The dispersion has a solid content of 1.3 – 1.7 wt.%, a viscosity of 5 – 12 mPa.s and fine particles (D50 = 80 nm, D90 = 100 nm), suiting it to spin coating of thin films. Each 100 ml of solution is supplied in a light resistant bottle fitted with a temperature indicator. This material has appeared in published work on perovskite tandem solar modules (Nat. Energy, 2022) and inverted perovskite solar cells (ACS Appl. Mater. Interfaces, 2023).
