Photonic light trapping in silicon nanowire arrays: deriving and overcoming the physical limitations

  journal={arXiv: Optics},
Hexagonally aligned, free-standing silicon nanowire (SiNW) arrays serve as photonic resonators which, as compared to a silicon (Si) thin film, do not only absorb more visible (VIS) and near-infrared (NIR) light, but also show an inherent photonic light concentration that enhances their performance as solar absorbers. Using numerical simulations we show, how light concentration is induced by high optical cross sections of the individual SiNWs but cannot be optimized independently of the SiNW…

Engineering gratings for light trapping in photovoltaics: The supercell concept

The question of the optimal surface structure for light trapping is widely debated in thin-film solar cell research. Here we propose a generic design approach that can tailor the strength of the

Photonic light-trapping versus Lambertian limits in thin film silicon solar cells with 1D and 2D periodic patterns.

The main physical effects of patterning are focused on, namely a reduction of reflection losses, diffraction of light in air or inside the cell, and coupling of incident radiation into quasi-guided optical modes of the structure, which is characteristic of photonic light-trapping.

Fundamental limit of nanophotonic light trapping in solar cells

A statistical temporal coupled-mode theory of light trapping based on a rigorous electromagnetic approach is developed, revealing that the conventional limit can be substantially surpassed when optical modes exhibit deep-subwavelength-scale field confinement, opening new avenues for highly efficient next-generation solar cells.
