Organic solar cells provide a good alternative to conventional, silicon based photovoltaics, since they are cheaper and easy to produce. A key issue for further optimization of the power conversion efficiency is to understand fundamental loss mechanisms such as charge carrier recombination. One important parameter influencing the nongeminate recombination is the charge carrier mobility. In this work we studied the mobility in bulk heterojunction solar cells based on P3HT:PC60BM and low-bandgap:PC70BM by different charge extraction techniques. We discuss impact of carrier concentration, field and temperature dependence of the mobility on the recombination losses.
