Inhalt:

Lecture / Exercise / Lab work The lecture will give an introduction to coating and printing technologies for the manufacturing of (opto-)electronic devices by solution processing. Special emphasis will be on upscaling from lab scale devices to large area commercial products. The fundamentals of the different technologies as well as their application for the manufacturing of active layers, transparent electrodes and transparent barriers will be described in detail. Exercises will provide a more quantitative approach to thin film processing while lab work will allow hands on experience of the lecture content.

Lernziele und Kompetenzen:

• The students will be introduced to the inventory of printing, coating and patterning technologies available for the solution processing of organic, hybrid and inorganic (opto-)electronic devices (FETs, LEDs, solar cells and photodetectors) and its application to the manufacturing of organic, perovskite and quantum dot devices.

After discussing the fundamentals of wet film deposition (wetting, viscosity, drying), the working principles and application ranges of coating (spin coating, doctor blading, slot die coating), printing (letter press, gravure, flexo, screen, ink jet printing) as well as of patterning techniques (printing, scratching, laser ablation) will be introduced. The specific requirements of “printed electronics” will be introduced and compared to those of “silicon based electronics” on one hand and “visual printing” on the other hand. The students will learn how to manufacture transparent electrodes (thin metal films, finger electrodes, nanowire meshes, transparent conductive oxides), active layers (bulk heterojunctions, perovskite films, nanoparticle layers), and barriers from the respective inks. They will also learn how to decide for the appropriate coating/printing technology. The inventory of materials for printed electronics will be presented and concepts for rational development of inks from these materials (Hansen solubility theory) will be introduced.

• Exercises will teach the students to base their decisions for materials, coating/printing technologies and patterning methods on quantitative considerations. These will include the calculation of resistance losses in transparent electrodes, of the viscosities and surface tensions of inks as well as of the water vapor transmission rates of barriers.

• Deposition and patterning of electrodes, active layers, and barriers for organic or perovskite solar cells will be trained in the lab work.
