Organic photovoltaics: With tailored materials on the move to future technology — •Peter Bäuerle — Universitaet Ulm, Institut fuer Organische Chemie II und Neue Materialien

The lecture will give an introduction to organic photovoltaics (OPV) and discuss the state-of-the-art of this future technology. The progress and the problems in the development of novel organic semiconducting materials based on small molecules, and in particular oligothiophenes will be described.[1]

Very recently, we could increase the efficiency in vacuum-processed small molecule organic solar cells to (record) values of 6.9-7.7% for single junction cells[2] and (world record) values of 12.0% for multi-stack cells.[3] The technology of light-weight, flexible, and semi-transparent organic solarfoils is starting to be commercialized and first applications in building and car integration will appear on the market soon.[4]
