Interplay of annealing temperature and doping in hole selective rear contacts based on silicon-rich silicon-carbide thin films

Christophe Ballif, Gizem Nogay, Franz-Josef Haug, Matthieu Despeisse, Monica Morales Masis, Philipp Friedrich Hermann Löper, Philippe Wyss, Oscar Esteban Rucavado Leandro, Josua Andreas Stückelberger

We present a detailed optimization of a hole selective rear contact for p-type crystalline silicon solar cells which relies on full-area processes and provides full-area passivation. The passivating hole-contact is based on a layer stack comprising a chemi ...

Passivating electron contact based on highly crystalline nanostructured silicon oxide layers for silicon solar cells

Christophe Ballif, Franz-Josef Haug, Quentin Thomas Jeangros, Xavier Niquille, Matthieu Despeisse, Philippe Wyss, Gizem Nogay, Martin Ledinsky, Philipp Friedrich Hermann Löper, Josua Andreas Stückelberger

We present a novel passivating contact structure based on a nanostructured silicon-based layer. Traditional poly-Si junctions feature excellent junction characteristics but their optical absorption induces current losses when applied to the solar cell fron ...

Nanocrystalline Silicon Carrier Collectors for Silicon Heterojunction Solar Cells and Impact on Low-Temperature Device Characteristics

Christophe Ballif, Franz-Josef Haug, Quentin Thomas Jeangros, Nicolas Würsch, Stefaan De Wolf, Gizem Nogay, Johannes Peter Seif, Yannick Samuel Riesen, Andrea Tomasi

Silicon heterojunction solar cells typically use stacks of hydrogenated intrinsic/doped amorphous silicon layers as carrier selective contacts. However, the use of these layers may cause parasitic optical absorption losses and moderate fill factor (FF) val ...

Silicon-Rich Silicon Carbide Hole-Selective Rear Contacts for Crystalline-Silicon-Based Solar Cells

Christophe Ballif, Franz-Josef Haug, Quentin Thomas Jeangros, Xavier Niquille, Matthieu Despeisse, Gizem Nogay, Philipp Friedrich Hermann Löper, Philippe Wyss, Josua Andreas Stückelberger

The use of passivating contacts compatible with typical homojunction thermal processes is one of the most promising approaches to realizing high-efficiency silicon solar cells. In this work, we investigate an alternative rear-passivating contact targeting ...

Strategies for Doped Nanocrystalline Silicon Integration in Silicon Heterojunction Solar Cells

Christophe Ballif, Aïcha Hessler-Wyser, Antoine Descoeudres, Jonas Geissbühler, Gizem Nogay, Stefaan De Wolf, Martin Ledinsky, Martial Duchamp, Johannes Peter Seif, Simon Hänni

Carrier collection in silicon heterojunction (SHJ) solar cells is usually achieved by doped amorphous silicon layers of a few nanometers, deposited at opposite sides of the crystalline silicon wafer. These layers are often defect-rich, resulting in modest ...

Structural peculiarities and aging effect in hydrogenated a-Si prepared by inductively coupled plasma assisted chemical vapor deposition technique

Gizem Nogay

In this study, we report the morphological and structural properties of amorphous and nanocrystalline Si thin films deposited by inductively coupled plasma-assisted chemical vapor deposition (ICP-CVD) technique at low substrate temperatures using H-2 dilut ...
