Organic solar cells （OSCs） have advantages like light-weight, flexibility, colorfulness and solution processability [1 ]. The active layer of OSCs generally contains two organic semiconductors： an electron donor and an electron acceptor. The donor and acceptor make nanoscale phase separation to allow efficient exciton dissociation and also form a three-dimensional （3D） passage to rapidly transfer free charge carriers to respective electrodes.
