From Molecular Junction to Bulk Heterojunction-Rectification and Photovoltaic Effect in Organic Materials
Abstract:
Conjugated organic molecules and polymers have been studied widely for their electro-optic properties. In this talk, I will discuss our recent effort in developing conjugated diblock co-oligomers as molecular diodes, which consist of donor and acceptor blocks covalently connected. Charge transport measurements through single molecular diodedemonstrated rectification effect. Experiments to unambiguously prove the molecular origin of this rectification effect will be presented. The molecular diodes are further assembled in cross-bar structures that were shown to exhibit photovotaic effect. Based on this work, conjugated diblock copolymers were developed for solar cell applications. This talk will also present our recent effort in polymeric solar cells. A series of new polymers with exceptional power conversion efficiency will be discussed.
