Metallization of Si heterojunction solar cells by nanosecond laser ablation and Ni-Cu plating

Christophe Ballif, Aïcha Hessler-Wyser, Ali Dabirian, Matthieu Despeisse, Jan-Willem Alexander Schüttauf, Monica Morales Masis, Bertrand Yves Paul Paviet-Salomon

A key step in industrialization of photovoltaics (PV) is the development of low-cost and large-area metallization processes to substitute the standard screen-printing process of silver paste. Thus Cu and Ni metallization processes enabled by laser patterni ...

Solar-to-Hydrogen Production at 14.2% Efficiency with Silicon Photovoltaics and Earth-Abundant Electrocatalysts

Christophe Ballif, Antonio Delfino, Antonin Faes, Demetri Psaltis, David Lambelet, Matthieu Despeisse, Christophe Moser, Jan-Willem Alexander Schüttauf, Julien Claude Bailat, Miguel Antonio Modestino, Enrico Chinello

Affordable, stable and earth-abundant photo-electrochemical materials are indispensable for the large-scale implementation of sunlight-driven hydrogen production. Here we present an intrinsically stable and scalable solar water splitting device that is ful ...

Quantification of Valleys of Randomly Textured Substrates as a Function of Opening Angle: Correlation to the Defect Density in Intrinsic nc-Si:H

Simon Hänni, Jan-Willem Alexander Schüttauf

Optical and electrical properties of hydrogenated nanocrystalline silicon (nc-Si:H) solar cells are strongly influenced by the morphology of underlying substrates. By texturing the substrates, the photogenerated current of nc-Si:H solar cells can increase ...

Metal versus dielectric back reflector for thin-film Si solar cells with impact of front electrode surface texture

Franz-Josef Haug, Jan-Willem Alexander Schüttauf, Etienne Antoine Julien Moulin, Chunmin Zhang

Thin-film Si solar cells employ a back reflector (BR) for a more efficient use of the long wavelength light. Here, we have carried out a cross evaluation of metal (Ag-based) and dielectric (white paint-based) BR designs. Conclusive results have been reache ...

Light-induced Voc increase and decrease in high-efficiency amorphous silicon solar cells

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Michael Elias Stückelberger, Yannick Samuel Riesen, Jan-Willem Alexander Schüttauf

High-efficiency amorphous silicon (a-Si:H) solar cells were deposited with different thicknesses of the p-type amorphous silicon carbide layer on substrates of varying roughness. We observed a light-induced open-circuit voltage (Voc) increase upon light so ...

Comparison of amorphous silicon absorber materials: Light-induced degradation and solar cell efficiency

Christophe Ballif, Grégory Bugnon, Franz-Josef Haug, Matthieu Despeisse, Michael Elias Stückelberger, Jan-Willem Alexander Schüttauf

Several amorphous silicon (a-Si:H) deposition conditions have been reported to produce films that degrade least under light soaking when incorporated into a-Si:H solar cells. However, a systematic comparison of these a-Si:H materials has never been present ...
