Rigorous Treatment of Photon Recycling in Thermodynamics of Photovoltaics: The Case of Perovskite Thin-Film Solar Cells
Muluneh G. Abebe, Aimi Abass, Guillaume Gomard +5
The establishment of a rigorous theory on thermodynamics of light management in photovoltaics that accommodates various loss mechanisms as well as wave-optical effects in the absor…
Plane wave coupling formalism for T-matrix simulations of light scattering by non-spherical particles
Dominik Theobald, Amos Egel, Guillaume Gomard +1
The computation of light scattering by the superposition T-matrix scheme has been so far restricted to systems made of particles that are either sparsely distributed or of near-sph…
Extending the applicability of the T-matrix method to light scattering by flat particles on a substrate via truncation of Sommerfeld integrals
Amos Egel, Yuri Eremin, Thomas Wriedt +3
The simulation of light scattering by particles on a substrate with the -matrix method relies on the expansion of the scattered field in spherical waves, followed by a plane wav…
Current dependence of the hot-spot response spectrum of superconducting single-photon detectors with different layouts
I. Charaev, A. Semenov, S. Doerner +3
We show that avoiding bends in a current-carrying superconducting nanowire enhances the probability for low energy photons to be detected and that this enhancement is entirely due…
Absorption enhancement in photonic crystal thin films by pseudo disordered perturbations
Romain Peretti, Guillaume Gomard, Loïc Lalouat +2
The effects resulting from the introduction of a controlled perturbation in a single pattern membrane on its absorption are first studied and then analyzed on the basis of band fol…
Blue light absorption enhancement based on vertically channelling modes in nano-holes arrays
Guillaume Gomard, Romain Peretti, Ségolène Callard +6
We investigate the specific optical regime occurring at short wavelengths, in the high absorption regime, in silicon thin-films patterned by periodically arranged nano-holes. Near-…
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…
Absorption control in pseudodisordered photonic-crystal thin film
Romain Peretti, Guillaume Gomard, Loïc Lalouat +2
The positive effects of various perturbations introduced in a bidimensional photonic-crystal patterned membrane on its integrated absorption are investigated numerically and theore…
Modal approach for tailoring the absorption in a photonic crystal membrane
Romain Peretti, Guillaume Gomard, Christian Seassal +2
In this paper, we propose a method for tailoring the absorption in a photonic crystal membrane. For that purpose, we first applied Time Domain Coupled Mode Theory to such a subwave…
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…
