4. Studies of Morphology and Charge-Transfer in Bulk-Heterojunction Polymer Solar Cells
Abstract : The work presented in this thesis focuses on the two critical issues of bulk-heterojunction polymer solar cells: morphology of active layers and energy loss during charge transfer process at electron donor/acceptor interfaces. Both issues determine the performance of polymer solar cells through governing exciton dissociation, charge carrier recombination and free charge carrier transport. READ MORE
