Three-dimensional in situ imaging of single-grain growth in polycrystalline In2O3:Zr films

Quentin Thomas Jeangros, Monica Morales Masis, Michael Elias Stückelberger

Understanding grain morphology and kinetics of solid-phase crystallization is important for controlling the functional properties of polycrystalline materials. Here, in situ coherent X-ray diffraction imaging and transmission electron microscopy elucidate ...

Bridging the p-type transparent conductive materials gap: synthesis approaches for disperse valence band materials

Monica Morales Masis, Angela Nicole Fioretti

Transparent conductive materials (TCMs) with high p-type conductivity and broadband transparency have remained elusive for years. Despite decades of research, no p-type material has yet been found to match the performance of n-type TCMs. If developed, the ...

Exploring co-sputtering of ZnO:Al and SiO2 for efficient electron-selective contacts on silicon solar cells

Christophe Ballif, Quentin Thomas Jeangros, Mathieu Gérard Boccard, Monica Morales Masis, Sihua Zhong, Weiliang Wu

In recent years, considerable efforts have been devoted to developing novel electron-selective materials for crystalline Si(c-Si) solar cells with the attempts to simplify the fabrication process and improve efficiency. In this study, ZnO:Al (AZO) is co-sp ...

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

Christophe Ballif, Bertrand Yves Paul Paviet-Salomon, Laurie-Lou Senaud, Matthieu Despeisse, Mathieu Gérard Boccard, Monica Morales Masis, Jan Haschke, Luca Massimiliano Antognini, Jean Cattin, Oscar Esteban Rucavado Leandro, Raphaël Monnard, Julie Amandine Dreon, Vincent Philippe Paratte, Olivier Denis Dupré, Angela Nicole Fioretti, Sihua Zhong

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 ...

Zr-doped indium oxide electrodes: Annealing and thickness effects on microstructure and carrier transport

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

Zr-doped indium oxide (In2O3:Zr) has been shown to satisfy the requirements of low resistance, wide band gap, and high infrared transmittance for application as a front contact in broadband solar cells. However, the reduction of indium usage in front of tr ...

Crystalline Silicon Solar Cells With Coannealed Electron- and Hole-Selective SiCx Passivating Contacts

Christophe Ballif, Franz-Josef Haug, Quentin Thomas Jeangros, Andrea Ingenito, Monica Morales Masis, Gizem Nogay, Philipp Friedrich Hermann Löper, Philippe Wyss, Oscar Esteban Rucavado Leandro, Josua Andreas Stückelberger

We present electron- and hole-selective passivating contacts based on wet-chemically grown interfacial SiOx and overlying in-situ doped silicon carbide (SiCx) deposited by plasma-enhanced chemical vapor deposition. After annealing at 850 degrees C, excelle ...

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, Björn Niesen, Monica Morales Masis, Soo-Jin Moon, Loris Barraud, Laura Ding, Jérémie Werner, Gizem Nogay, Matthias Wolfgang Bräuninger, Oscar Esteban Rucavado Leandro, Raphaël Monnard, Fan Fu, Chien-Jen Yang, Peter Joseph Fiala

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 ...
