Experimental Evaluation of the Light Trapping Potential of Optical Nanostructures for Thin-Film Silicon Solar Cells

Christophe Ballif, Corsin Battaglia, Jordi Escarre Palou, Mathieu Gérard Boccard, Karin Söderström

We describe a method based on nanoimprinting and non-absorbing insulating silicon nitride electrodes for evaluating the light trapping potential of photonic nanostructures for thin-film silicon solar cells. We validate our method by relating the optical re ...

On the Interplay Between Microstructure and Interfaces in High-Efficiency Microcrystalline Silicon Solar Cells

Christophe Ballif, Marco Cantoni, Duncan Thomas Lindsay Alexander, Corsin Battaglia, Jordi Escarre Palou, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay, Grégory Bugnon, Laura Ding, Gaetano Parascandolo, Peter Cuony, Simon Hänni

This paper gives new insights into the role of both the microstructure and the interfaces in microcrystalline silicon (μc- Si) single-junction solar cells. A 3-D tomographic reconstruction of a μc-Si solar cell reveals the 2-D nature of the porous zones, w ...

Nanomoulding of transparent zinc oxide electrodes for efficient light trapping in solar cells

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia, Jordi Escarre Palou, Matthieu Despeisse, Karin Söderström, Mathieu Charrière

Nanopatterning has gained tremendous importance in the field of photovoltaics, as absorption of sunlight in solar cells can be enhanced drastically by proper engineering of photonic nanostructures1– 8. However, despite intensive efforts, neither the ideal ...

Window layer with p doped silicon oxide for high V-oc thin-film silicon n-i-p solar cells

Christophe Ballif, Franz-Josef Haug, Jordi Escarre Palou, Céline Pahud, Rémi Biron

We investigate the influence of the oxygen content in boron-doped nanocrystalline silicon oxide films (p-nc-SiOx) and introduce this material as window layer in n-i-p solar cells. The dependence of both, optical and electrical properties on the oxygen cont ...

High fidelity transfer of nanometric random textures by UV embossing for thin film solar cells applications

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia, Jordi Escarre Palou, Karin Söderström

We investigate the transfer of random nanostructures commonly used in thin film silicon solar cells onto inexpensive substrates, such as glass or flexible polyethylene sheets. Morphological and optical analyses of masters and replicas show the successful t ...

Nanoimprint Lithography for High-Efficiency Thin-Film Silicon Solar Cells

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia, Jordi Escarre Palou, Matthieu Despeisse, Mathieu Gérard Boccard, Stefaan De Wolf, Grégory Bugnon, Loris Barraud, Laura Ding, Karin Söderström, Adrian Billet

We demonstrate high-efficiency thin-film silicon solar cells with transparent nanotextured front electrodes fabricated via ultraviolet nanoimprint lithography on glass substrates. By replicating the morphology of state-of-the-art nanotextured zinc oxide fr ...

Micromorph thin-film silicon solar cells with transparent high-mobility hydrogenated indium oxide front electrodes

We investigate the performance of hydrogenated indium oxide as a transparent front electrode for micromorph thin-film silicon solar cells on glass. Light trapping is achieved by replicating the morphology of state-of-the-art zinc oxide electrodes, known fo ...

Highly reflective nanotextured sputtered silver back reflector for flexible high-efficiency n–i–p thin-film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Jordi Escarre Palou, Karin Söderström, Céline Pahud, Rémi Biron

High reflectivity is essential when a metal is used as back contact and reflector in thin-film silicon solar cells. We show that thermal annealing at 150 °C improves the reflectivity of silver films deposited by sputtering at room temperature on nanotextur ...
