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 ...

Charge Collection in Hybrid Perovskite Solar Cells: Relation to the Nanoscale Elemental Distribution

Christophe Ballif, Björn Niesen, Michael Elias Stückelberger, Jérémie Werner

Unveiling the correlation between elemental composition, Fermi-level splitting, and charge collection in perovskite solar cells (PSCs) when exposed to different environments is crucial to understanding the origin of defects. This will enable defect enginee ...

Comparison of LPCVD and sputter-etched ZnO layers applied as front electrodes in tandem thin-film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Grégory Bugnon, Michael Elias Stückelberger, Etienne Antoine Julien Moulin

Aluminum-doped zinc oxide (ZnO:Al) layers deposited by sputtering and boron-doped zinc oxide (ZnO:B) layers deposited by low-pressure chemical vapor deposition (LPCVD) are well-established materials for front electrodes in thin-film silicon solar cells. In ...

Nanohole Structuring for Improved Performance of Hydrogenated Amorphous Silicon Photovoltaics

Michael Elias Stückelberger, Gizem Nogay

While low hole mobilities limit the current collection and efficiency of hydrogenated amorphous silicon (a-Si:H) photovoltaic devices, attempts to improve mobility of the material directly have stagnated. Herein, we explore a method of utilizing nanostruct ...
