| Résumé | We study the ground state and excited state geometry, and detailed electronic structure of the germafluorene based polymer PGFDTBT and C 70 interface. The charge transfer is studied by analyzing the charge densities of individual orbitals near the HOMO and LUMO. Our results indicate that the charge transfer at the ground state of Polymer:C 70 interface is negligible, while the efficient charge transfer from polymer to C 70 takes place upon excitation. The transfer is enabled by a "bridging state" which is energetically in between the "hole state" and the "charge separated" state. ©The Electrochemical Society. |
