Popular Aqueous PEDOT:PSS Formulation

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


P VP AI 4083 (CAS number 155090-83-8) is one of the most commonly used aqueous PEDOT:PSS formulations. Due to its deep work function it is often used for the matching of interfacial energy levels in thin film electronic devices. With a PEDOT:PSS ratio of 1:6, AI 4083 has low conductivity with relatively high resistance of 500 to 5000 Ω.cm. It has been widely used in organic and inverted PSCs and OLEDs as a hole transport material.
