Aqueous PEDOT:PSS Formulation

Used for applications in OPV and perovskite solar cells


Clevios™ HTL Solar is an aqueous PEDOT:PSS formulation designed for use in thin film electronics as an interfacial material. The advantage of the HTL Solar formulation is its improved wetting properties, particularly in inverted OPV cells, compared to the other PEDOT:PSS formulations in our catalogue.
