Organic Electronics and Organic Semiconductors

Organic electronics and organic semiconductors are Organic photodetectors and solar cells generate elec-
key technologies in the field of microelectronics. With tricity from light and are used to measure light intensity
their help, it is possible to create large-area, flexible, and wavelength or to generate energy. Organic lasers
semi-transparent, ultra-thin and extremely energy- are based on organic semiconductors. Organic semicon-
efficient products. Due to the low material usage (only ductor components such as transistors, diodes and
a few grams per square meter) and the established triodes allow the construction of circuits that offer appli-
production methods, low production costs can also cation scenarios beyond the established silicon-based

molecules that can be synthesized, offers the possibility
of finding the right materials for every application. Prof. Karl Leo is an internationally recognized researcher
in condensed matter physics. Among his achievements
are the first observations of coherent electronic dyna-
mics in solids and pioneering work on organic semicon-
ductors. Many of these technologies were successfully
transferred to spin-off companies like Novaled and
Heliatek. His main current research interests are novel
organic electronic devices (Organic Devices and Structures
Group) and organic sensors (Organic Sensors Group).

Prof. Leo has been rewarded with the DFG's 2002 Leib-
nitz Award, the German President's 2011 German
Future Award, and the European Patent Office's Euro-
pean Inventors Award.
