Abstract: Organic solar cell device performance is largely determined by various interfaces, including the anode/organic or cathode/organic interfaces for efficient hole or electron extraction, selective electron or hole transport and exciton blocking, organic-organic heterojunction (OOH) for exciton dissociation, and so on. In the first part of the presentation, with the appliance of defect induced gap states model, the energy level alignment at the OOH interface of selected model donor-acceptor systems has been studied, as well as the interface nanostructuring. Secondly, two effective novel anode interfacial layers in organic solar cell application were investigated by device evaluation and energy diagram analysis.
