摘要
We introduce that a conjugated random terpolymer (LGC-D013) with N-alkylthieno[3,4-dpyrrole-4,6-dione (TPD, the acceptor) and benzodithiophene (BDT) and terthiophene (the donor units) can efficiently function as a novel hole-transporting material (HTM) for high-performance planar perovskite solar cells (PeSCs). The roles of the LGC-D013 HTM on PeSC-performances were examined using filed-emission scanning electron microscope, atomic force microscope, photoluminescence, hole mobility, energy-level diagram, and device-resistances. The LGC-D013 based device produced a high power conversion efficiency (PCE) of 12.22%, which was 22% enhancement compared to the reference poly (3-hexylthiophene) (P313T) based device with a PCE of 9.53%. These results suggest that the random terpolymer LGC-D013 can be considered as an effective HTM to produce a high efficiency PeSC.
