Scalable simple liquid deposition techniques for the enhancement of light absorption in thin films: Distributed Bragg reflectors coupled to 1D nanoimprinted textures

AIP Advances, 2017
Light trapping within a light absorbing medium is a key to highly efficient thin film solar cells. We propose a large-scale procedure based on materials with low absorption for the fabrication of combined Distributed Bragg Reflector (DBR) and grating ...

Low-cost optical manipulation using hanging droplets of PDMS [PDF]

, 2015
We propose and demonstrate a low-cost optical micromanipulation system that makes use of simple microfrabricated components coupled to a smartphone camera for imaging. Layering hanging droplets of polydimethylsiloxane (PDMS) on microscope coverslips, and

Coherent population trapping in quantized light field [PDF]

, 2005
A full quantum treatment of coherent population trapping (CPT) is given for a system of resonantly coupled atoms and electromagnetic field. We develop a regular analytical method of the construction of generalized dark states (GDS). It turns out that GDS

Light-trapping modes in lossy plasmonic waveguides

AIP Advances, 2019
Light-trapping modes can exist in lossless plasmonic waveguides. Here, we investigate the effect of metallic loss on light-trapping modes using the usual complex wave vector (β)-real frequency (ω) formulation and an alternative real β-complex ω ...

Light trapping in ultrathin plasmonic solar cells [PDF]

, 2010
We report on the design, fabrication, and measurement of ultrathin film a-Si:H solar cells with nanostructured plasmonic back contacts, which demonstrate enhanced short circuit current densities compared to cells having flat or randomly textured back ...

Vortex revivals with trapped light

Optics Letters, 2001
We predict that vortex dipoles nested in light beams trapped in graded-index media can undergo closed Berry trajectories, yielding periodic vortex annihilations and revivals along the light-propagation direction. The vortex revivals from vortex-free wave fronts are mediated by Freund stationary point bundles that carry the necessary Poincaré-Hopf ...

Angular constraint on light-trapping absorption enhancement in solar cells

, 2010
Light trapping for solar cells can reduce production cost and improve energy conversion efficiency. Understanding some of the basic theoretical constraints on light trapping is therefore of fundamental importance.
