A Study on the Charge Carrier Transport of Passivating Contacts

Gizem Nogay

Recently, the charge carrier transport mechanism of passivating contacts, which feature an ultra-thin oxide layer, has been investigated by studying temperature-dependent current-voltage (I-V) characteristics. The measurement revealed that tunneling is the ...

Measuring carrier injection from amorphous silicon into crystalline silicon using photoluminescence

Gizem Nogay, Philipp Friedrich Hermann Löper

In devices with intrinsic amorphous silicon layer on a crystalline silicon substrate, the light absorbed in the amorphous layer can be weakly electronically coupled into the silicon base. Such carrier injection has previously been reported from measurement ...

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 ...

Full-Area Passivating Contacts with High and Low Thermal Budgets: Solutions for High Efficiency c-Si Solar Cells

Gizem Nogay

Today more than 90% of the global PV market is covered by c-Si solar cells which are limited by recombination losses at the metal-semiconductor interface. This recombination path can be avoided by separating the metal from the c-Si wafer by introducing a b ...

A passivating contact concept compatible with a short thermal treatment

Christophe Ballif, Franz-Josef Haug, Andrea Ingenito, Matthieu Despeisse, Gizem Nogay, Philippe Wyss, Josua Andreas Stückelberger

In this study we present a boron-doped silicon carbide layers as a hole-selective contact which is compatible with short annealing time (typically < 1 minute) as the one used for firing of metal pastes. The application of such layers on symmetrically proce ...

Impact Impact of different capping layers on carrier injection efficiency between amorphous and crystalline silicon measured using photoluminescence

Andrea Ingenito, Gizem Nogay, Philipp Friedrich Hermann Löper

Intrinsic amorphous silicon provides excellent surface passivation on crystalline silicon. It has previously been shown, that carriers that are photo generated in the amorphous silicon can be efficiently electronically injected into the crystalline silicon ...

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

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 ...
