Silicon oxide buffer layer at the p-i interface in amorphous and microcrystalline silicon solar cells

Christophe Ballif, Matthieu Despeisse, Gaetano Parascandolo, Grégory Bugnon, Michael Elias Stückelberger, Mathieu Charrière

The use of intrinsic silicon oxide as a buffer layer at the p-i interface of thin-film silicon solar cells is shown to provide significant advantages. For microcrystalline silicon solar cells, when associated with highly crystalline i-layers deposited at h ...

9.4% Efficient Amorphous Silicon Solar Cell on High Aspect-Ratio Glass Microcones

Christophe Ballif, Corsin Battaglia, Mathieu Charrière, Hyunjung Park

High aspect-ratio three-dimensional (3D) a-Si:H solar cells have been fabricated to enhance a light absorption path while maintaining a short carrier collection length. Substantial efficiency enhancement in 3D solar cells was achieved due to the boost in J ...

Light Harvesting Schemes for High Efficiency Thin Film Silicon Solar Cells

Christophe Ballif, Corsin Battaglia, Matthieu Despeisse, Jordi Escarre Palou, Mathieu Gérard Boccard, Sylvain Nicolay, Laura Ding, Gaetano Parascandolo, Grégory Bugnon, Peter Cuony

In Thin Film Silicon (TF-Si) solar cells light harvesting schemes must guarantee an efficient light trapping in the thin absorber layers without decreasing the silicon layers quality and consecutively the p-i-n diodes electrical performance. TF-Si solar ce ...

Light trapping in solar cells: can periodic beat random?

Christophe Ballif, Franz-Josef Haug, Marco Cantoni, Duncan Thomas Lindsay Alexander, Corsin Battaglia, Matthieu Despeisse, Jordi Escarre Palou, Mathieu Gérard Boccard, Karin Söderström, Mathieu Charrière

Theory predicts that periodic photonic nanostructures should outperform their random counterparts in trapping light in solar cells. However, the current certified world-record conversion efficiency for amorphous silicon thin-film solar cells, which strongl ...
