The approximate CNDOL Fockian, together with the configuration interaction of single excitations ([CIS|CNDOL/21]), is applied to investigate the electronic properties of three different kinds of donors (D) considered suitable for photovoltaic devices, either as isolated systems or complexed with fullerene (C 60 ) as potential acceptors (A). Calculated charge maps, together with the Coulomb-exchange term of CIS lowest transitions, are used to understand the electronic topology and possible behaviour of D-A excitons. The effects of varying donor structures are compared. The lowest excitation energies of the donor-C 60  complexes arise from electron densities localised at the central ring units in the donors. Nevertheless, C 60  does not always participate in electron sharing upon excitation. It sometimes acts only as a structural companion for enhancing or not the exciton capability to provide adequate photoelectric power conversion efficiencies. The [CIS|CNDOL/21] method is validated as a valuable tool for modelling structure-related properties of molecular excitons and for predicting the performance of D–A materials in relatively big supramolecular systems. It is shown that multi-electron CIS wavefunctions are at least as useful as one-electron molecular orbitals to describe charge-transfer properties of excitons and provide a physical picture of the whole electron density.
