lasmonics have been recognized as promising platform
that may premise the enhanced performance of next-
generation optoelectronic devices. Plasmonic effects have
been proposed as a solution to overcome the limited light
absorption of thin film photovoltaic devices and diverse
types of plasmonic solar cells have been developed.
Recently, we made a comprehensive overview of the
state-of-the-art progress on the design and fabrication of
plasmonic solar cells as well as the understanding of the
enhancement mechanism. In this presentation, we propose
a few strategies to develop viable plasmonic DSSCs and OPVs
based on metal-graphene oxide core-shell nanostructures
or lithographically-induced plasmonic nanopatterns. Very
recently metal halide perovskites have been attractive as
solar energy harvesters due to efficient ambipolar transport
and strong light absorption. They have rapidly advanced thin
film photovoltaic performance; as a result, the observed
instabilities urgently require a solution. We report the
reduced-dimensionality (quasi-2D) perovskite films that
exhibit improved stability in solar cell performance while
retaining the high performance of conventional three-
dimensional perovskites. The quasi-2D perovskites were
also employed to develop limiting emitting diodes with the
most bright and highest EQE. We provide an overview of the
recent progress of perovskite-based photodetectors focusing
on versatile compositions, structures, and morphologies
of constituent materials, and diverse device architectures
toward the superior performance metrics.
