State of the art organic solar cells exhibit power conversion efficiencies of 18 % and above. These devices benefit from a significant suppression of free charge recombination with regard to the Langevin-limit of charge encounter in a homogeneous medium. It has been recognized that the main cause of suppressed free charge recombination is the reformation and
