Surface plasma resonance enhanced photocurrent generation in NiO photoanode based solar cells

Surface Plasmon Resonance Effect in Inverted Perovskite Solar Cells

“…X‐ray diffraction (XRD) analysis in Figure S1 (Supporting Information) exhibits a common pattern of bulk gold as well as a broad peak at around 25° corresponding to amorphous silica. Au@SiO 2 nanoparticles with different AR can be obtained by adjusting either Au seeds or the content of the growth solution . The corresponding absorption characterization of these Au nanostructures is shown in Figure S2 (Supporting Information).…”

Performances Enhancement in Perovskite Solar Cells by Incorporating Plasmonic Au NRs@SiO2 at Absorber/HTL Interface

“…It has been proven that the introduction of metal particles could induce charge recombination around the metal surface, and such negative effect can be successfully inhibited by coating a thin insulating film surrounding their surface . The insulating SiO 2 shell may impede the aggregation of Au NRs and prevent direct contact between Au and the hole conductor spiro‐OMeTAD, or perovskite active layer, inhibiting the unwanted charge recombination within the device.…”

“…The key feature of this approach is that we can take advantage of the SPR at a lower concentration and the Au NRs have larger light scattering section than Au NPs . To prevent recombination losses and to not adverse for the spectral response, a thin insulating SiO 2 film is coated around the Au NRs . Comprehensive optical and electrical characterizations to clarify the influence of plasmonic Au NRs@SiO 2 on exciton generation, dissociation, and charge recombination within the devices are further performed.…”

Light absorption enhancement by embedding submicron scattering TiO2nanoparticles in perovskite solar cells

“…Hybrid perovskite solar cells (PSCs), as a rising star in thin-lm photovoltaic devices with superior advantages in power conversion and fabrication cost, 11 are also expected to achieve further photovoltaic performance improvement through the effective light manipulation. Recently, modied TiO 2 electron extraction layer, [12][13][14][15] patterned FTO substrates, 16,17 metallic plasmonic NPs, [18][19][20] roughed interfaces 21 or other functionalized nanostructures 22,23 have been employed or proposed to improve the light trapping in the PSC devices. Especially, as a widely used anode material with low cost, abundant synthesizable morphologies and reliable electron transport property, nanostructured TiO 2 shows the promising light manipulation ability in PSCs, similar to that in the conventional DSSCs.…”
