Electronic devices based on organic semiconductors: overview and recent progress

Graduate School of Physics and Chemistry of Bordeaux (ENSCPB)

Abstract
 
Recent progress has been made in the use of organic semiconductors in electronic devices in the last 20 years. Organic semiconductors are a new class of materials that provide interesting electronic properties as well as many advantages compared to conventional inorganic semiconductors. Since they are organics, polymers or low molecular weight compounds, they are easy to process in thin films, with low temperature techniques, and low-cost to produce thanks to organic chemistry.
Nowadays, the most developed devices are Organic Light-Emitting Diodes (OLEDs). They are promising as a new technology for manufacturing of emissive displays. Commercialisation of OLEDs-based displays is now in full expansion. It is believes that OLEDs will also be used as lighting sources in the future.
Organic semiconductors can also be used as active layers of photovoltaic cells (PV). As a new source of renewable energy, research in the field of organic solar cells has also expanded. The aim is to produce low-cost solar modules.
Finally, field-effect transistors (FETs) can also be made of organic semiconductors. Such devices open the route of organic electronics and the possibility to produce low-cost circuits and chips.
After a brief presentation of organic semiconductors, operating basics as well as manufacturing processes will be presented. Recent progress as well as research from our facilities in Bordeaux (France) will be reported.
