摘要: Abstract A conjugated polymer poly (9,9-dioctyfluorene-co-benzothiazole) (F8BT) was used as the electron transporting layer (ETL) to modify cathode interface of inverted planar perovskite solar cell. Incorporation thin F8BT delivered greatly enhanced power conversion efficiency (PCE) 13.9% compared PCE 7.9% device without F8BT, due improvements in various performance parameters like V oc , J sc and FF . Moreover, great elimination hysteresis demonstrated based devices. These results suggest promising potential polymeric materials cells possible approach eliminate with this class interfacial materials.
