Back reflectors with periodic gratings for light trapping in a-SiGe:H solar cells

Autor: C. Ducros, Fabrice Emieux, Alexandre Pereira, H. Szambolics

Publikováno v: Thin Solid Films. 620:10-16

In the present study, we introduce a new method for preparing textured reflectors for thin film solar cells: this novel design of textured surfaces increases light trapping in tandem solar cells. The structure under study comprises periodic nanoislan

Publikováno v: 2016 15th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm).

For various pulsed power electronics like, metal oxide semiconductor field-effect transistor (MOSFET), insulating gate bipolar transistor (IGBT), Gate turn-off thyristor (GTO), Integrated gate-commutated thyristor (IGCT), heat loads are often in the

The propagation of magnetic domain walls induced by spin-polarized currents has launched new concepts for memory and logic devices. A wave of studies focusing on permalloy (NiFe) nanowires has found evidence for high domain-wall velocities (100 m s(-

Although we lack clear experimental evidence, apparently out-of-plane magnetized systems are better suited for spintronic applications than the in-plane magnetized ones, mainly due to the smaller current densities required for achieving domain wall m

A constrained finite element formulation for the Landau–Lifshitz–Gilbert equations

Autor: H. Szambolics, Jean-Christophe Toussaint, Olivier Fruchart, Liliana D. Buda-Prejbeanu

Publikováno v: Computational Materials Science. 44:253-258

A finite element formalism is proposed to solve the dynamic micromagnetic equations. To estimate the validity and the accuracy of this finite element approach, the results of two bidimensional test cases are compared with a finite difference approach

Nanostructured refractory thin films for solar applications

Autor: H. Szambolics, N. Dunoyer, Emmanuel Ollier, Olivier Dellea

Publikováno v: Nanostructured Thin Films VII.

Selective solar absorbers are key elements of all solar thermal systems. Solar thermal panels and Concentrated Solar Power (CSP) systems aim respectively at producing heat and electricity. In both cases, a surface receives the solar radiation and is

Journal of Nanoparticle Research, 2012, 14, pp.1085_1-9

In this study, the synthesis of Ge nanoparticles by a physical vapour deposition (PVD) nanocluster source has been investigated. We typically obtain Ge nanoparticles with a mean diameter between 4 and 9 nm. The microstructure of Ge nanoparticles was
