Anti-refl ection (AR) coatings designed for glass and other rigid, inorganic substrates are commercially available; however, these inorganic AR coatings tend to crack or delaminate on fl exible substrates. A polymeric fi lm with a gradient refractive

We studied the competition between energy loss due to quenching and enhanced absorption arising from the near-field plasmonic effect of Au nanoparticles (NPs) on the performance of organic solar cells (OSCs), by fabricating inverted architecture OSCs

We investigated numerically an all-dielectric semiconductor-based circular polarizer consisting of silicon helix on glass substrate. Only three turns of the dielectric helix structure provides extremely high polarization suppression ratio above 2,300

We present here the design of a robust broadband high efficiency surface-normal vertical to in-plane optical coupler using fourth-order gratings. The fourth-order gratings can be designed such that the zero-order diffraction is suppressed while the d

Inverted pyramid surface textures are demonstrated on flexible amorphous Si solar cells based on a resin imprint process. The surface texture reduces the reflectivity of the cells over a broad spectrum. The texture leads to relative cell efficiency i

We present design criteria to demonstrate nanostructured high performance anti-reflection coatings that allows over 98.5% transmission over a broad visible spectral range with cone angles up to 120°. We propose a methodology to relate the nanostruct

Graded index polymer films enable novel optics using rigid or flexible substrates, such as waveguides or anti-reflection coatings. Previously, such films have been fabricated by nanoimprint lithography or the decomposition of a single component in po
