Abstract/Summary:


Light funnel arrays serve as an efficient absorbing layers on account of their light trapping capabilities associated with the excitation of three-dimensional complex Mie modes. Specifically, broadband absorption enhancement of the solar spectrum is noticeable for free floating light funnel arrays. We show that a light funnel (LF) arrays with bottom LF diameter of 100 nm and height of 4 μm exhibit absorption enhancement of ~52.4 % and ~12.5 % relative to thin film and an optimized nanopillar arrays.
