Surface Plasmon Resonance Effect in Inverted Perovskite Solar Cells.

ABSTRACT: This work reports on incorporation of spectrally tuned gold/silica (Au/SiO₂) core/shell nanospheres and nanorods into the inverted perovskite solar cells (PVSC). The band gap of hybrid lead halide iodide (CH₃NH₃PbI₃) can be gradually increased by replacing iodide with increasing amounts of bromide, which can not only offer an appreciate solar radiation window for the surface plasmon resonance effect utilization, but also potentially result in a large open circuit voltage. The introduction of localized surface plasmons in CH₃NH₃PbI_2.85Br_0.15-based photovoltaic system, which occur in response to electromagnetic radiation, has shown dramatic enhancement of exciton dissociation. The synchronized improvement
