Thanks to the continuous improvement of crystalline silicon (c-Si) solar cells, largely dominating the market, photovoltaic electricity is nowadays the cheapest source of energy on the market. Yet, solar energy is far from being completely harvested, as t ...
EPFL2023Characterization and Development of Fired Passivating Contacts for Silicon Solar Cells
One of the key elements to improve mainstream crystalline silicon (c-Si) solar cell performance is surface passivation, which is at the center of the ongoing transition from cells with direct silicon-metal contacts to full area passivating contacts. In the ...

In this article, the effect of the various processing steps during the fabrication of c-Si/SiOx/SiCx fired passivating contacts on the silicon bulk lifetime is studied, and the kinetics of defect deactivation by hydrogenation is investigated. It is found t ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Carrier-selective contacts using metal compounds for crystalline silicon solar cells
Mathieu Gérard Boccard, Julie Amandine Dreon
Solar cells rely on the efficient generation of electrons and holes and the subsequent collection of these photoexcited charge carriers at spatially separated electrodes. High wafer quality is now commonplace for crystalline silicon (c-Si) based solar cell ...
WILEY2022Material Development for Perovskite/Silicon Tandem Photovoltaics
The developed world is built on the fact that energy is readily available and functionally infinite. The electricity from the wall, the gas at the station, and the heat in our homes are reliable and low-cost. But this comfort is so far only possible throug ...

Christophe Ballif, Franz-Josef Haug, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Andrea Ingenito, Matthieu Despeisse, Philippe Wyss, Mario Joe Lehmann
High temperature passivating contacts for c-Si based solar cells are intensively studied because of their potential in boosting solar cell efficiency while being compatible with industrial processes at high temperatures. In this work, the hydrogenation mec ...
2019Interplay of annealing temperature and doping in hole selective rear contacts based on silicon-rich silicon-carbide thin films
Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Monica Morales Masis, Gizem Nogay, 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 ...
Elsevier Science Bv2017Antihydrogen accumulation for fundamental symmetry tests
Antihydrogen, a positron bound to an antiproton, is the simplest anti-atom. Its structure and properties are expected to mirror those of the hydrogen atom. Prospects for precision comparisons of the two, as tests of fundamental symmetries, are driving a vi ...
