TL;DR: In this article, the authors study absorption enhancement by light scattering at periodically textured interfaces in thin-film silicon solar cells and show that the periodicity establishes resonant coupling to propagating waveguide modes.

TL;DR: Based on the simulations, triangular gratings with a very sharp slope in one side, so called sawtooth gratings, are the most promising 1D gratings for optimal light trapping.

TL;DR: By improved processing of the nanoparticles, the simulations show that the nanoparticle concept could outperform traditional back reflectors and a better fit is obtained by introducing a porous interfacial layer between the silver and zinc oxide.

TL;DR: In this paper, an apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array comprising a multitude of transmissive or reflective microlenses which are regularly arranged at a lens pitch P and an illumination unit comprising an array of light sources for emitting light of a wavelength L each and having an aperture each.

TL;DR: The proposed approach to analytically calculate the Goos-Haenchen shift in one- and two-dimensional periodic structures is shown to be a fast, simple, and efficient method that can provide good physical insight to the nature of the phenomenon.
