Conjugated interfacial charge separation

There is a close relationship between the morphology of active layers and performance (physical processes) of conjugated-polymer-based photovoltaic cells, which is quite important for the further performance improvement. The morphological characteristics include ordered packing of donor/acceptor materials, domain size, phase-separation stracture and interfacial diffusion structure, while physical processes include exciton diffusion, charge-transfer state separation, lifetime of charge carrier, and carrier mobility.
