73. Annual meeting of the German Physical Society (Condensed Matter)

Dresden from March 22th - 27th, 2009.

Symposium on Thursday, March 26th, 2009:

"Organic Photovoltaics: from Single Molecules to Devices"

Joined Symposium of the Sections: Chemical Physics and Polymer Physics (CPP), Thin Films (DS), Semiconductor Physics (HL), Surface Physics (O)
in combination with Oral and Poster Sessions organized by the CPP Section from March 25th-27th.

The world energy crisis creates a strong demand for energy generation from regenerative resources such as e.g. the sun. Organic photovoltaics open a route to cheap, flexible, light and large-area devices. However, so far the efficiency and in particular the stability of organic photovoltaic devices cannot compete with their inorganic counterparts. Finding the solution to this complex problem is an interdisciplinary task, which crosses the boundaries of the disciplines of material science, physics and electrical engineering. The symposium will cover organic solar cells, including, organic solid-state devices, cells based on electrolytes, and dye-sensitized devices. The aim of this symposium is to stimulate a stronger interaction and exchange between scientists from different research fields using different approaches such as computer simulation, experiment and theory. Emphasis is in particular given to the interrelation between the local properties of the photoactive layers, elementary processes and the device performance.

In particular, we would like to stress on the following topics and approaches:
  • Investigations of all elementary processes within the device: This includes electronic and optical properties such as excitonic-states, pairs of polarons, charge carriers, etc..
  • Interfaces and heterojunctions: Investigations contributing to a general understanding of the basic elementary charge transfer processes, open-circuit voltage limiting energy levels and charge carrier transport levels.
  • Correlation between the structure and morphology of the photoactive layers, the electronic and photophysical properties and the parameters of the devices.
  • Correlation between local (opto)electronic and photophysical properties of the photoactive layers and the device performance.
  • Investigations on the fundamental origin of the limited stability of the (opto)electronic and photophysical properties of the photoactive layers and devices.
  • Recent advances and developments in (opto)electronic and photophysical characterization methods, in particular with high spatial resolution as e.g. in ultrafast spectroscopy, (time-resolved) electrostatic force microscopy or broadband optical near-field microscopy.
