Abstract

We will present a selection of disordered and hybrid plasmonic systems for broadband energy harvesting and conversion in a context of photocatalysis. Firstly, disordered plasmonic nanoparticle arrays coupled to an underlying Fabry Perot cavity show a material-independent light harvesting response, enabling the decoupling of the far-field light collection behaviour and local near-field enhancement. Specifically we elucidate how cluster-deposited highly disordered systems made out of a variety of different metals (Au, Ag, Pt) show the same far-field reflection profile determined solely by the resonance wavelength of the underlying cavity, enabling efficient light harvesting in hybrid systems composed of plasmonic and catalytic metal nanoclusters. Secondly, we will examine hybrid plasmonic nanoparticle assemblies for efficient conversion of photon energy into energetic charge carriers for photocatalysis.
