Low-Temperature Screen-Printed Metallization for the Scale-Up of Two-Terminal Perovskite-Silicon Tandems

Christophe Ballif, Antonin Faes, Jacques Levrat, Gabriel Christmann, Bertrand Yves Paul Paviet-Salomon, Arnaud Walter, Nicolas Badel, Adriana Paracchino, Matthieu Despeisse, Sylvain Nicolay

Tandem photovoltaic devices based on perovskite and crystalline silicon (PK/c-Si) absorbers have the potential to push commercial silicon single junction devices beyond their current efficiency limit. However, their scale-up to industrially relevant sizes ...

Paths for maximal light incoupling and excellent electrical performances in silicon heterojunction solar cells

Christophe Ballif, Bertrand Yves Paul Paviet-Salomon, Matthieu Despeisse, Laurie-Lou Senaud, Mathieu Gérard Boccard, Monica Morales Masis, Jan Haschke, Luca Massimiliano Antognini, Jean Cattin, Oscar Esteban Rucavado Leandro

We discuss here optical losses in silicon heterojunction solar cells and strategies to minimize them. Optical losses originate from most non-crystalline-silicon layers involved in the solar cell. A breakdown for typical values is shown evidencing that supp ...

Rear-emitter silicon heterojunction solar cells with atomic layer deposited ZnO:Al serving as an alternative transparent conducting oxide to In2O3:Sn

Christophe Ballif, Antoine Descoeudres, Gabriel Christmann, Nicolas Badel, Matthieu Despeisse, Sylvain Nicolay, Loris Barraud

Here high-efficiency (above 21%) large-area silicon heterojunction solar cells with atomic layer deposited ZnO:Al as front- or back-side transparent conducting oxide are demonstrated. Photoconductance decay measurements indicate that the excellent chemical ...

Field test and electrode optimization of electrodynamic cleaning systems for solar panels

Christophe Ballif, Aïcha Hessler-Wyser, Antonin Faes, Jacques Levrat, Nicolas Badel, Nicolas Würsch, Matthieu Despeisse

Soiling is the major cause of power loss of photovoltaics (PV) and concentrated solar power (CSP) in desert areas. Electrodynamic cleaning system (EDS) is an automatic and water-free integrated cleaning system for mirrors or solar panels, which uses pulsed ...

Analysis of hydrogen distribution and migration in fired passivating contacts (FPC)

Christophe Ballif, Franz-Josef Haug, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Andrea Ingenito, Matthieu Despeisse, Philippe Wyss, Mario Joe Lehmann

High temperature passivating contacts for c-Si based solar cells are intensively studied because of their potential in boosting solar cell efficiency while being compatible with industrial processes at high temperatures. In this work, the hydrogenation mec ...

Reassessment of cell to module gains and losses: Accounting for the current boost specific to cells located on the edges

Christophe Ballif, Olivier Denis Dupré, Jacques Levrat, Matthieu Despeisse, Mathieu Gérard Boccard

The power produced by a photovoltaic module is not simply the sum of the powers of its constituents cells. The difference stems from a number of so-called “cell-to-module” (CTM) gain or loss mechanisms. These are getting more and more attention as improvem ...

Silicon Heterojunction Solar Cells on Quasi-mono Wafers

Christophe Ballif, Antoine Descoeudres, Matthieu Despeisse, Mathieu Gérard Boccard, Loris Barraud, Jan Haschke, Raphaël Monnard, Brahim Aissa

We applied hydrogen passivation, gettering and a combination of both to quasi-mono (qm) wafer material to enhance its bulk lifetime and prepared silicon heterojunction (SHJ) solar cells. We find that while our applied hydrogen passivation alone seems not t ...
