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, Soo-Jin Moon, Laura Ding

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 ...

Realization of GaInP/Si Dual-Junction Solar Cells With 29.8% 1-Sun Efficiency

Christophe Ballif, Antoine Descoeudres, Antonin Faes, Jacques Levrat, Bertrand Yves Paul Paviet-Salomon, Nicolas Badel, Matthieu Despeisse, Loris Barraud, Stephanie Essig

Combining a Si solar cell with a high-bandgap top cell reduces the thermalization losses in the short wavelength and enables theoretical 1-sun efficiencies far over 30%. We have investigated the fabrication and optimization of Si-based tandem solar cells w ...

Silicon Heterojunction Solar Cells With Copper-Plated Grid Electrodes: Status and Comparison With Silver Thick-Film Techniques

Christophe Ballif, Quentin Thomas Jeangros, Antoine Descoeudres, Antonin Faes, Jonas Geissbühler, Nicolas Badel, Matthieu Despeisse, Stefaan De Wolf, Loris Barraud, Andrea Tomasi

Copper electroplating is investigated and compared with common silver printing techniques for the front metallization of silicon heterojunction solar cells. We achieve smaller feature sizes by electroplating, significantly reducing optical shadowing losses ...

Dynamic behaviour of SOFC short stacks

Jan Van Herle, Raphaël Ihringer, Nicolas Badel, Nordahl Autissier, Diego Larrain, Joseph Sfeir

Electrical output behaviour obtained on solid oxide fuel cell stacks, based on planar anode supported cells (50 or 100 cm2 active area) and metallic interconnects, is reported. Stacks (1–12 cells) have been operated with cathode air and anode hydrogen flow ...
