Fraunhofer IFAM
Screen Printing Technology For Printed Electronics Manufacturing
Mario Kohl
Function-integrated components are in the focus of various industrial sectors. Functional printing enables a high functional density and customization of products for individual customers. Fraunhofer IFAM has extensive experience in the development of printing inks and pastes for the targeted functional integration of components and structures. The development of printing technologies at Fraunhofer IFAM is directly linked to the development of functional materials associated with new technologies. A wide range of materials are used, from metals and alloys to polymers and composites.
These materials can then be used to print functional structures. In addition to printing conductive paths or complete circuit boards, a variety of sensors can be applied directly at Fraunhofer IFAM. Examples of printed sensors include strain gauges, temperature sensors and capacitive sensors, among others. Active elements such as actuators and heaters can also be printed.
One of the processes used by the experts at Fraunhofer IFAM for functional printing is screen printing. As a well-established process, screen printing offers robust production quality, high throughput rates and good resolution.

Advancements in Printed Electronics Prototyping: Direct Ink Write Technology for Printed Multi-Layer Flexible Electronics
Mal Manchur
The evolution of printed electronics has been significantly influenced by additive manufacturing techniques, such as direct ink write (DIW) technology. This masterclass examines the application of DIW in the development of flexible printed circuits, emphasizing its capacity for rapid design iteration using materials that are scalable to screen printed manufacturing processes.
The masterclass will also highlight how DIW technology compares to other technologies, such as inkjet. Special attention will be given to the use of materials, such as silver-, gold-, copper-, and carbon-based inks, their adhesion with various substrates including PET, TPU, and polyimide, and will also cover sheer thinning and nozzle compatibility. Attendees will leave with a deeper understanding of the interdependencies between ink and substrate characteristics, enabling informed decision-making in the selection of materials and a dispensing system for printing functional, flexible hybrid electronics.
This presentation is particularly relevant for academics, researchers, materials scientists, and engineers involved in the design and prototyping of next-generation electronic devices.

Life Cycle Assessment of Printed Electronics: Challenges, Insights and Opportunities
Zikulnig Johanna
This masterclass provides an introduction to conducting Life Cycle Assessments (LCA) in the context of printed electronics, using real-world examples from disposable sensor applications such as point-of-care diagnostics and smart packaging. The session will cover key methodological choices, such as defining appropriate system boundaries, interpreting data, and considering end-of-life scenarios.
Key findings from our recent research will be presented, highlighting environmental hotspots, the influence of material selection, and current methodological limitations of LCA. The session concludes with a discussion of scientific strategies to tackle these challenges, including design-for-recycling concepts, modular architectures, and the use of alternative or bio-based materials to support more sustainable development in printed electronics.

Advancing PCB Technology Through Additive Manufacturing: Process, Sustainability, and Reliability
Lina Kadura
As electronics manufacturing faces growing pressure to reduce its environmental footprint, additive manufacturing offers a compelling alternative to traditional subtractive PCB fabrication. This masterclass introduces the field of printed and hybrid electronics, highlighting how additive processes enable more sustainable, material-efficient production methods for modern electronics.
We will explore real-world application examples, from concept to finished device, with a deep technical dive into material validation, design rules, fabrication techniques, testing, and assembly. Special emphasis will be placed on the sustainability gains of additive methods, supported by life cycle assessment (LCA) results for selected use cases.

Stable and efficient architectures for perovskite solar modules and tandems
Tom Aernouts
The unprecedented fast rise of power conversion efficiency (PCE) of perovskite-based solar cells (PSC) in recent years has created a vast worldwide research activity in this material class for photovoltaic and other opto-electronic applications. Several materials compositions and device architectures have been described and best reported PCE’s yield recently up to 27%. Also improved stability under specific conditions has been shown for specific architectures. Whereas all these results indicate a high potential for this novel solar technology, further steps must be taken to convince industry and even the whole PV community that perovskite-based photovoltaics can really emerge from the lab into industrially applicable solar module processing.
Similarly, the perovskite PV technology has boosted the tandem research whereby perovskite cells and modules are placed on top of other PV devices like Si or CIGS solar cells. Impressive lab scale results surpassing 35% PCE have been reported. New challenges arise when this needs to be upscaled to full wafer or module size.
The challenges ahead to scale up perovskite PV technology to full modules and large area tandems, suitable for long term outdoor use, will be discussed.
