Micrometer-Thin Crystalline-Silicon Solar Cells Integrating Numerically Optimized 2-D Photonic Crystals
V. Depauw, X. Meng, O. El Daif +7
A 2-D photonic crystal was integrated experimentally into a thin-film crystalline-silicon solar cell of 1-μm thickness, after numerical optimization maximizing light absorption in…
Down Converter Device Combining Rare-Earth Doped Thin Layer and Photonic Crystal for c-Si Based Solar Cell
Thierry Deschamps, Emmanuel Drouard, Romain Peretti +7
The aim of the study is to develop ultra-compact structures enabling an efficient conversion of single high energy photon (UV) to two lower energy photons (IR). The proposed struct…
Absorbing photonic crystals for thin film photovoltaics
O. El Daif, E. Drouard, G. Gomard +9
The absorption of thin hydrogenated amorphous silicon layers can be efficiently enhanced through a controlled periodic patterning. Light is trapped through coupling with photonic B…
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…
