Removing Facial Features From Structural Mri Images Biases Visual Quality Assessment

Elda Fischi Gomez, Patric Hagmann, Jonas Richiardi, Oscar Esteban Rucavado Leandro, Thomas Sanchez

A critical step before data-sharing of human neuroimaging is removing facial features to protect individuals' privacy. However, not only does this process redact identifiable information about individuals, but it also removes non-identifiable information. ...

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 ...

Defect passivation in zinc tin oxide: improving the transparency-conductivity trade-off and comparing with indium-based materials

Oscar Esteban Rucavado Leandro

Transparent conductive oxides (TCOs) are essential in technologies coupling light and electricity. Due to their good optoelectronic properties and the production scalability, Sn-doped indium oxide (In2O3:Sn) is the preferred TCO in industrial applications. ...

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 ...
