Development of an unconventional electron paramagnetic resonance detection technique for selective probing of photogenerated and extracted charge carriers inoptelectronic and photovoltaic devices by means of pulsed field induced extraction

In the first funding period we successfully developed the envisioned EPR method OTRACE-EDMR for a selective probing of photo-generated and extracted charge carriers in opto-electronic and photovoltaic devices by means of pulsed, field-induced extraction under EPR conditions. Our method determines quantitatively the impact of spin-dependent recombination on state-of-the-art thin-film organic solar cells. In the second funding period we will widen our focus and apply this method additionally to a variety of material systems and devices, such as organic-inorganic hybrid solar cells and OLEDs.
