Gold nanoparticles (Au NPs) face challenges in broadband light harvesting due to limited spectral coverage and low photothermal efficiency. This study compares spherical Au NPs with anisotropic Au nanostructures, including nanospheres and nanocorals, for enhanced absorption. Their optical and photothermal properties are tested in photo-thermoelectric generators for efficient energy conversion.

Abstract
Gold nanoparticles (Au NPs) face challenges in broadband light harvesting due to limited spectral coverage and low photothermal efficiency. This study compares spherical Au NPs with anisotropic Au nanostructures, including nanospheres and nanocorals, for enhanced absorption. Their optical and photothermal properties are tested in photo-thermoelectric generators for efficient energy conversion.
