摘要
The disclosure relates to organic photovoltaic cells comprising a heterojunction structure formed by a first organic donor layer and a first organic acceptor layer, and further comprising a second organic acceptor layer adjacent to the first organic acceptor layer and/or a second organic donor layer adjacent to the first organic donor layer. The materials of the first acceptor layer and the second acceptor layer are selected to allow exciton dissociation by charge transfer at their interface, and to simultaneously allow exciton energy transfer at their interface. The materials of the first donor layer and the second donor layer are selected to allow exciton dissociation by charge transfer at their interface, and to simultaneously allow exciton energy transfer at their interface. Organic photovoltaic cells of the present invention may have a high short-circuit current density, a good open-circuit voltage and a good fill factor.
