Abstract
We analyze high order of nongeminate recombination in organic donor–acceptor bulk heterojunction solar cells. The model of recombination where an exciton annihilates on an electron–hole Langevin bound pair near donor–acceptor interface has been applied in our studies. We obtained satisfactory agreement between experimental results and theoretical calculations for the concentration dependences of several parameters characterizing photovoltaic cells, such as the mobility of charge carriers, the recombination coefficient and the recombination time. The influence of carriers from deep states on the mobility has been taken into account.
