A study employed a low cost, chemical stable, solution processing polymer and thermal treatment free poly(2-ethyl-2-oxazoline) (PEOz) nanodots as an efficient interfacial layer on the top of [6,6]-phenyl-C61-butyricacid methyl (PCBM) to fabricate inverted planar heterojunction (PHJ) perovskite solar Cells. The study demonstrated that PEOz could effectively reduce the work function of silver electrode to form an ohmic contact between PCBM and silver, which enhanced the electron extraction capability from PCBM to Ag electrode. Theperformance of perovskite solar cells increased from 9.01% to 14.52% after inserting a thin layer of PEOz between PCBM and Ag.
