Qualitative and quantitative characterization of loss mechanisms in organic solar cells

Background information: Organic semiconductor devices (solar cells or light-emitting diodes) possess advantages concerning possible applications and production costs. Nevertheless, the performance and the lifetime of the organic semiconductor-based devices need to be improved. To overcome these issues, intensive fundamental collaborative research efforts are necessary to clarify the recombination processes during the conversion process of light into electricity (or vice versa). Some of these recombination channels are spin-dependent and need to be experimentally addressed in a more quantitative way to assess their relevance to device performance.

Project: Various experiments will be performed that are based on the principles of electron spin resonance and charge extraction methods. Fully processed devices will be studied in a broad temperature range. The basic idea is to compare the density of photogenerated charges in organic device upon application of the ac- and dc- resonant magnetic fields.

The University of Würzburg, home of 6 Nobel prize winners in physics and 5 in chemistry, was founded in 1402. It enrols more than 28,000 students. The Chair of Experimental Physics VI (Energy research) was founded by Prof. V. Dyakonov in 2004, and has since built up an international reputation in fields such as thin-film photovoltaics and spin-related phenomena in semiconductors.
