Light trapping in solar cells: numerical modeling with measured surface textures

Christophe Ballif, Franz-Josef Haug, Mathieu Gérard Boccard, Beat Ruhstaller, Thomas Andreas Lanz

We present and experimentally validate a computational model for the light propagation in thin-film solar cells that integrates non-paraxial scalar diffraction theory with non-sequential ray-tracing. The model allows computing the spectral layer absorbance ...

Electrothermal Finite-Element Modeling for Defect Characterization in Thin-Film Silicon Solar Modules

Christophe Ballif, Michael Elias Stückelberger, Beat Ruhstaller, Christian Frédéric Schlumpf, Thomas Andreas Lanz, Mathias Bonmarin

We present and validate a finite-element model for coupled charge and heat transport in monolithically interconnected thin-film solar modules. Using measured current-voltage (I-V) and lock-in thermography (LIT) measurements of amorphous silicon minimodules ...

Influence of crystalline titanium oxide layer smoothness on the performance of inverted organic bilayer solar cells

Roland Hany, Gaëtan Wicht, Hui Zhang, Thomas Andreas Lanz

Due to the small exciton diffusion length in organic materials, the donor-acceptor heterointerface in simple bilayer solar cells must be placed in close proximity to the bottom electrode. This makes great demands on the planarity of the base layer, since a ...

Extended light scattering model incorporating coherence for thin-film silicon solar cells

Christophe Ballif, Corsin Battaglia, Beat Ruhstaller, Thomas Andreas Lanz

We present a comprehensive scalar light-scattering model for the optical simulation of silicon thin film solar cells. The model integrates coherent light propagation in thin layers with a direct, noniterative treatment of light scattered at rough layer int ...
