Photonic assisted light trapping integrated in ultrathin crystalline silicon solar cells by nanoimprint lithography
Christos Trompoukis, Ounsi El Daif, Valérie Depauw +2
We report on the fabrication of two-dimensional periodic photonic nanostructures by nanoimprint lithography and dry etching, and their integration into a 1-μm-thin mono-crystalline…
Influence of the pattern shape on the photonic efficiency of front-side periodically patterned ultrathin crystalline silicon solar cells
Aline Herman, Christos Trompoukis, Valerie Depauw +2
Patterning the front side of an ultra-thin crystalline silicon (c Si) solar cell helps keeping the energy conversion efficiency high by compensating for the light absorption losses…
Nonlinear relaxation of 0-dimension-trapped microcavity polaritons
Ounsi El Daif, Gael Nardin, Taofiq K. Paraiso +6
We study the emission properties of confined polariton states in shallow zero-dimensional traps under non-resonant excitation. We evidence several relaxation regimes. For slightly…
Absorption enhancement in amorphous silicon photonic crystals for thin film photovoltaic solar cells
Ounsi El Daif, Emmanuel Drouard, Yeonsang Park +8
We report on very high enhancement of thin layer's absorption through band-engineering of a photonic crystal structure. We realized amorphous silicon (aSi) photonic crystals, where…
Engineering the spatial confinement of exciton-polaritons in semiconductors
Reda Idrissi Kaitouni, Ounsi El Daif, Maxime Richard +8
We demonstrate the spatial confinement of electronic excitations in a solid state system, within novel artificial structures that can be designed having arbitrary dimensionality an…
