Computational Modeling of Thin-Film Silicon Solar Cells and Modules

Thomas Andreas Lanz

Solar photovoltaic energy production relies on the direct conversion of sunlight into electricity. Silicon thin-film solar cells represent a reliable and environmentally friendly technology to make photovoltaics economically viable. As these solar cells do ...

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

Christophe Ballif, Michael Elias Stückelberger, Thomas Andreas Lanz

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 ...

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

Christophe Ballif, Franz-Josef Haug, Mathieu Gérard Boccard, 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 ...

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

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 ...
