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 ...

Self-Patterned Nanoparticle Layers for Vertical Interconnects: Application in Tandem Solar Cells

Christophe Ballif, Aïcha Hessler-Wyser, Fanny Sculati-Meillaud, Nicolas Blondiaux, Raphaël Pugin, Franz-Josef Haug, Mathieu Gérard Boccard, Michael Elias Stückelberger, Emmanuel Scolan, Björn Niesen

We demonstrate self-patterned insulating nanoparticle layers to define local electrical interconnects in thin-film electronic devices. We show this with thin-film silicon tandem solar cells, where we introduce between the two component cells a solution-pro ...

Electrothermal Finite-Element Modeling for Defect Characterization in Thin-Film Silicon Solar Modules

Christophe Ballif, Mathias Bonmarin, Michael Elias Stückelberger, Thomas Andreas Lanz, Beat Ruhstaller, Christian Frédéric Schlumpf

We present and validate a finite-element model for coupled charge and heat transport in monolithically interconnected thin-film solar modules. Using measured current-voltage (I-V) and lock-in thermography (LIT) measurements of amorphous silicon minimodules ...

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 ...

Time evolution of surface defect states in hydrogenated amorphous silicon studied by photothermal and photocurrent spectroscopy and optical simulation

Christophe Ballif, Matthieu Despeisse, Michael Elias Stückelberger, Jakub Holovsky

The time evolution of surface defect density and width of space charge region in thin layer of amorphous silicon is observed experimentally by Fourier transform photocurrent spectroscopy. This work reviews the assumption that photocurrent is insensitive to ...

Light Harvesting Schemes for High Efficiency Thin Film Silicon Solar Cells

Christophe Ballif, Mathieu Charrière, Peter Cuony, Gaetano Parascandolo, Laura Ding, Sylvain Nicolay, Grégory Bugnon, Mathieu Gérard Boccard, Matthieu Despeisse, Corsin Battaglia, Jordi Escarre Palou, Michael Elias Stückelberger, Maximilien Joseph Marie Bonnet-Eymard

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 ...

Resistive interlayer for improved performance of thin film silicon solar cells on highly textured substrate

Christophe Ballif, Andrea Feltrin, Peter Cuony, Grégory Bugnon, Adrian Billet, Matthieu Despeisse, Michael Elias Stückelberger

The deposition of thin-film silicon solar cells on highly textured substrates results in improved light trapping in the cell. However, the growth of silicon layers on rough substrates can often lead to undesired current drains, degrading performance and re ...
