摘要：

Anode modification by doping silver nano-particles (AgNPs) into poly(3,4-ethylene dioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) and cathode interfacial modification by inserting solution-processed bathophenanthroline (sBphen) in CH₃NH₃PbI_{3_x}Cl_x based planar perovskite solar cells are investigated. Prior to the optical effect such as localized surface plasmon resonance, the Ag-NPs distributed in PEDOT:PSS mainly cause an improvement in the electrical property of PEDOT:PSS�AgNPs composite films. The sBphen interfacial layer modified the surface morphology of perovskite/phenyl-C₆₁-butyric acid methyl ester (PC₆₁BM) films by filling the voids on the surface of perovskite/PC₆₁BM effectively, which led to an obvious improvement in the fill factor. Accordingly, an efficientdevice with a power conversion efficiency of 15.75% was achieved due to the simultaneous cathode and anode interfacial modification.
