Address: Dr. Carsten Deibel, Lehrstuhl für experimentelle Physik 6, Physikalisches Institut, Am Hubland 97074 Würzburg Germany
The group of experimental physics 6, in the Physikalisches Insitut, Julius, Maximilians University of Würzburg is mainly specialised in the field of organic photovoltaics.
We provide to researchers top levels facilities for photophysical (photo-induced absorption, transcient time-resolved and electron-spin resonnance spectroscopies, …) transport (FET characterisation, Time of Flight, CELIV, …) characterization, as well as device processing and simulation.
Our research activities are mainly focussed on the investigation of charge transfer and charge transport in ordered and disordered organic material systems.
The recruited researcher will take part of the European project SolarNType which is focused on the investigation of novel acceptor-type molecules for organic photovoltaics.
In polymer solar cells, the active layer is composed of a 2 materials blend, an electron acceptor and an electron donator, which performs exciton separation into charges as well as the transport of those charges to the electrodes. Fullerene derivatives have a quasi monopoly as electron acceptors in state of the art devices. The devices based on those molecules reach impressively efficient use of the wavelengths they absorb (external quantum efficiency until 80% for the best wavelengths) but are limited by their thin absorption spectrum.
The scientific challenge is to understand the mechanisms underlying the photocurrent generation, to finally process not fullerene blend reaching as high efficiency in the best wavelength but for a wider range of wavelength, thus enabling better use of the solar spectra.
The job involves several focuses whose relative importance is open to discussion: material characterization, process and morphology optimization and of course theoretical understanding and modeling.
As member of a European project, you will also be expected to work with and in the partner’s Institutes.
This position is part of the Marie Curie Research Training Network solarNtype,
http://www.solarntype.eu, devoted to cross-disciplinary training and research at the interface between physics and chemistry. Eligible applicants have to fulfill the requirements of the EU FP6 (see Marie Curie FAQ at http://ec.europa.eu/research/fp6/mariecurieactions/helpdesk/index.cfm, concerning eligible researchers for RTN-Research Training Networks), which implies that they have not resided or carried out their main
activity in Germany for more than 12 months within the past 3 years.
Applicants are expected to hold a PhD in physics, materials science, electrical engineering or a related area with a strong background in semiconductor physics and organic electronics. Qualified candidates have skills in electrical and photophysical characterization.
