Surface plasmon resonance (SPR) is widely used as light trapping schemes in solar
cells, because it can concentrate light fields surrounding metal nanostructures
and realize light management at the nanoscale. SPR in photovoltaics generally
occurs at the metal/dielectric interfaces. A well-defined interface is therefore
required to elucidate interfacial SPR processes. Here, we designed a photovoltaic
device (PVD) with an atomically flat TiO2 dielectric/dye/graphene/metal
nanoparticle (NP) interface for quantitatively studying the SPR enhancement of
the photovoltaic conversion. Theoretical and experimental results indicated that
the graphene monolayer was transparent to the electromagnetic field. This
transparency led to significant substrate-induced plasmonic hybridization at the
heterostructure interface. Combined with interparticle plasmonic coupling, the
substrate-induced plasmonics concentrated light at the interface and enhanced the
photo-excitation of dyes, thus improving the photoelectric conversion. Such a
mechanistic understanding of interfacial plasmonic enhancement will further
promote the development of efficient plasmon-enhanced solar cells and composite
photocatalysts.
