The electrostatic printing technology allows there use of a wider range of inks, essential for printing very fine structures
Fraunhofer IAP announce their scientists are working on implementing a novel drop-on demand system: esjet-printing (electro static printing). This technology allows the use of a wider range of inks, especially essential for printing very fine structures. Widening the range of possible inks regarding their viscosity is a big step.
In constrast, inkjet-printing sets limits to the used ink’s viscosity. With esjet-printing, fine metal grids with high transmission rates can be printed and thus replace conventional transparent ITO-electrodes in photovoltaics components.
"On our pilot plant we develop printing solutions in a very industry-oriented way. Together with our clients we then implement these solutions into their large scale plants based on the expertise we gather through our pilot plant. We improve our printing methods constantly and individually adapt them to our customers’ needs."

About Fraunhofer IAP
The Fraunhofer Institute for Applied Polymer Research IAP in Potsdam-Golm, Germany, specializes in research and development of polymer applications. It supports companies and partners in custom development and optimization of innovative and sustainable materials, processing aids and processes. In addition to the environmentally friendly, economical production, functionalization and processing of polymers in the laboratory and pilot plant scale, the institute also offers the characterization of polymers.
Synthetic petroleum-based polymers as well as biopolymers, polymers from renewable raw materials and chemically, physically or biologically functionalized polymers are in the focus of the institute’s work. The applications are diverse, ranging from biotechnology, medicine, pharmacy and cosmetics to electronics and optics as well as applications in the packaging, environmental and wastewater engineering or the aerospace, automotive, paper, construction and coatings industries.
The Fraunhofer IAP has been conducting research on organic electronic systems for over 25 years and focuses on solution-processed devices used in OLEDs, QLEDs, OTFT, OPV, perovskite solar cells, sensors and actuators.
Several processing technologies are available in a large clean room. These include spin coating, material evaluation in lab devices, advanced processing technologies, such as inkjet printing and high-precision slot die coating on a robot-controlled S2S pilot line for dimensions up to 150 mm x 150 mm, and various evaporation and encapsulation technologies.
