Hybrid sequential deposition process for fully textured perovskite/silicon tandem solar cells

Christophe Ballif, Quentin Thomas Jeangros, Davide Sacchetto, Bertrand Yves Paul Paviet-Salomon, Florent Sahli, Arnaud Walter, Gianluca Cattaneo, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay

Tandem solar cells that feature a high-bandgap perovskite cell on top of a lower bandgap silicon cell have the potential to reach efficiencies > 30%. Here, we present a versatile hybrid deposition method that yields conformal perovskite cells directly on t ...

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 ...

Enhancing the optoelectronic properties of amorphous zinc tin oxide by subgap defect passivation: A theoretical and experimental demonstration

Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Jakub Holovsky, Monica Morales Masis, Federica Landucci, Martial Duchamp, Oscar Esteban Rucavado Leandro

The link between sub-bandgap states and optoelectronic properties is investigated for amorphous zinc tin oxide (a-ZTO) thin films deposited by RF sputtering. a-ZTO samples were annealed up to 500 °C in oxidizing, neutral, and reducing atmospheres before ch ...

High performance amorphous Zn-Sn-O: impact of composition, microstructure, and thermal treatments in the optoelectronic properties

Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Monica Morales Masis, Federica Landucci, Oscar Esteban Rucavado Leandro

Zinc and tin oxides are both earth-abundant materials with demonstrated applicability as electrodes in several optoelectronic devices. The presence of grain boundaries in these polycrystalline films generally limits the electron mobility. By a combinatoria ...

Zinc tin oxide as high-temperature stable recombination layer for mesoscopic perovskite/silicon monolithic tandem solar cells

Christophe Ballif, Davide Sacchetto, Xavier Niquille, Arnaud Walter, Stefaan De Wolf, Sylvain Nicolay, Oscar Esteban Rucavado Leandro, Björn Niesen, Monica Morales Masis, Soo-Jin Moon

Perovskite/crystalline silicon tandem solar cells have the potential to reach efficiencies beyond those of silicon single-junction record devices. However, the high-temperature process of 500 °C needed for state-of-the-art mesoscopic perovskite cells has, ...
