Organic electronics involving organic semiconductors, organic light emitting diodes (OLED) possibly being the best known device in this group, is definitively one of the key technologies for the upcoming years. Organic semiconductors, consisting oligomers or polymer chain molecules, allow for the production of flexible, large-area devices of very low weight that can be manufactured at potentially very low costs.
To achieve high efficiency as well as long life times, similar to inorganic semiconductors, a precise control of the electrical and optical properties is essential. This, in turn, requires extremely high material purities, to allow for controlled doping to adjust the properties.
In our SEMINAR FUNCTIONAL LAYERS 'The art of OLED, OPV and Perovskite'. February 2nd, 2017 - we will briefly summarize a few basics on organic electronics and the materials involved, as well as the effect of material purity on the final device characteristics. We will focus on the purification of organic semiconductors by sublimation, discussing the working principle, the typical system design, as well advantages and limitations of this method.
•MATERIAL PURIFICATION BY SUBLIMATION
•PEROVSKITE AND OPV
•INKJETTING – CHALLENGES AND SOLUTIONS
•OLED SYSTEM CAPABILITIES.
