Abstract
We investigate a novel light conversion scheme in nanostructures for the highly demanding field of plasmonic solar cells. In our study, we incorporate vertical nanorods made of semiconductor materials, which are coupled optically to plasmonic nanoantennas for optimal absorption of sunlight. Utilizing the unique properties of localized surface plasmon resonances, we create dedicated nanoantenna elements such that the emission pattern is effectively directed toward the absorber material. In our approach, we use a computational finite element method to investigate the effects of size and shape of metallic nanoparticles to obtain an asymmetric radiation pattern that matches the geometry of our design.
