A scalable and inexpensive surface-texturization method for advanced transparent front electrodes in microcrystalline and micromorph thin film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Mathieu Gérard Boccard, Julien Claude Bailat, Yang Wang, Nils Linus Löfgren

As the thin film silicon solar cell technology reaches a pivotal point to keep competing in the photovoltaic industry where crystalline silicon and other technologies currently dominate, it has become an urgent task to revolutionize some of its state-of-th ...

Optimization of thin film silicon solar cells on highly textured substrates

Christophe Ballif, Corsin Battaglia, Matthieu Despeisse, Mathieu Gérard Boccard, Grégory Bugnon, Thomas Söderström, Gaetano Parascandolo, Peter Cuony, Simon Hänni, Mathieu Charrière, Nils Linus Löfgren

Doped layers made of nanostructured silicon phases embedded in a silicon oxide matrix were implemented in thin film silicon solar cells. Their combination with optimized deposition processes for the silicon intrinsic layers is shown to allow for an increas ...

Mixed phase silicon oxide layers for thin-film silicon solar cells

Christophe Ballif, Matthieu Despeisse, Peter Cuony, Nils Linus Löfgren, Michael Marending

Lower absorption, lower refractive index and tunable resistance are three advantages of doped silicon oxide containing nanocrystalline silicon grains (nc-SiOx) compared to doped microcrystalline silicon, for the use as p- and n-type layers in thin-film sil ...

Advanced nanostructured materials for pushing light trapping towards the Yablonovitch limit

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia, Jordi Escarre Palou, Matthieu Despeisse, Mathieu Gérard Boccard, Stefaan De Wolf, Sylvain Nicolay, Grégory Bugnon, Loris Barraud, Laura Ding, Michael Elias Stückelberger, Karin Söderström, Gaetano Parascandolo, Peter Cuony, Fanny Sculati-Meillaud, Simon Hänni, Adrian Billet, Mathieu Charrière, Nils Linus Löfgren

We give an overview on recent progress in the synthesis, fabrication and integration of advanced nanostructured materials for efficient light trapping in high-efficiency thin-film silicon solar cells. ...

Low-conductivity doped layers for improved performance of thin film silicon solar cells on highly textured substrate

Christophe Ballif, Corsin Battaglia, Matthieu Despeisse, Mathieu Gérard Boccard, Grégory Bugnon, Thomas Söderström, Michael Elias Stückelberger, Gaetano Parascandolo, Peter Cuony, Fanny Sculati-Meillaud, Simon Hänni, Adrian Billet, Mathieu Charrière, Nils Linus Löfgren

The performances of thin film silicon solar cells are reported for the use of increasingly rough zinc-oxide (ZnO) front electrodes. Experimental results show that textured substrates favor increased light trapping but also the local creation of undesired c ...
