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 ...

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 ...

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 ...

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 ...

Toward Annealing-Stable Molybdenum-Oxide-Based Hole-Selective Contacts For Silicon Photovoltaics

Christophe Ballif, Stephanie Essig, Jonas Geissbühler, Mathieu Gérard Boccard, Stefaan De Wolf, Monica Morales Masis, Jérémie Werner, Philipp Friedrich Hermann Löper, Oscar Esteban Rucavado Leandro, Julie Amandine Dreon

Molybdenum oxide (MoOX) combines a high work function with broadband optical transparency. Sandwiched between a hydrogenated intrinsic amorphous silicon passivation layer and a transparent conductive oxide, this material allows a highly efficient hole‐sele ...
