Comparison of amorphous silicon absorber materials: Kinetics of light-induced degradation

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Mathieu Gérard Boccard, Michael Elias Stückelberger, Yannick Samuel Riesen, Adrian Billet

We investigate the influence of the deposition parameters for intrinsic amorphous silicon absorber layers on light-induced degradation (LID) of thin-film silicon solar cells. The focus is on absorber layers with different bandgaps: on one side, solar cells ...

Explaining Morphological and Electrical Features of Boron-doped Zinc Oxide to Tailor New Electrodes for Photovoltaics

Lorenzo Fanni

TCOs are a class of metal oxides that combine transparency to visible light with electrical conductivity. Each TCO is characterized by the trade-off of these two properties which can be tuned for a particular application. This thesis is dedicated to the in ...

New method for lateral mapping of bimolecular recombination in thin-film organic solar cells

Wolfgang Richard Tress

The best organic solar cells are limited by bimolecular recombination. Tools to study these losses are available; however, they are only developed for small area (laboratory-scale) devices and are not yet available for large area (production-scale) devices ...

Thin-film silicon solar cells are often deposited on textured ZnO substrates. The solar-cell performance is strongly correlated to the substrate morphology, as this morphology determines light scattering, defective-region formation, and crystalline growth ...

The optical performance of tandem a-Si:H/mu c-Si:H (micromorph) thin film solar cell was investigated experimentally and by means of rigorous 3-D optical simulation. The interplay of intermediate reflectors, with different refractive indices and thicknesse ...

Post-deposition treatment of microcrystalline silicon solar cells for improved performance on rough superstrates

Christophe Ballif, Mathieu Gérard Boccard, Sylvain Nicolay, Grégory Bugnon, Laura Ding

In this contribution, we investigate the effect of post-deposition treatments on finished non-encapsulated thin-film microcrystalline silicon solar cells and show that annealing in vacuum leads to improved electrical properties of the solar cells, particul ...
