The importance of charge transfer(CT)complexes to the device efficiency in organic bulk heterojunction(BHJ)solar cells is a topic of recent high interest.[1] These studies have focused on the photogenerated CT complexes but the presence and effect of integer charge transfer(ICT)states[2] present in the dark and created as a consequence of Fermi level equilibrium has all but been ignored so far,despite indications of their significance.
