Heraeus recently announced its Conductive Polymers Division has contributed to the production of fully roll-to-roll printable organic photovoltaic energy cells (OPVs) by the Technical University of Denmark, Department of Energy Conservation and Storage (DTU). Printed Clevios™ PEDOT:PSS from Heraeus Conductive Polymers Division were used, rather than traditional vacuum processed indium tin oxide.
Clevios PEDOT:PSS is reportedly a highly conductive polymer dispersion that allows the deposition of transparent, thin conductive films with sheet resistances of less than 100 Ohm/sq. DTU was able to show that the use of Clevios PEDOT:PSS as an electrode in the layer stack contributes to the thin, lightweight and flexible properties of the OPV device. The Clevios material also can contribute to the low cost of this roll-to-roll produced energy device.
“Flexible Clevios PEDOT:PSS allows additional options, including low cost printing, in the production of OPV devices,” said Wilfied Lövenich, Ph.D., of Heraeus.
