Interplay 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, Philipp Friedrich Hermann Löper, Philippe Wyss, Gizem Nogay, 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 ...

Silicon-Rich Silicon Carbide Hole-Selective Rear Contacts for Crystalline-Silicon-Based Solar Cells

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Quentin Thomas Jeangros, Xavier Niquille, Gizem Nogay, Philipp Friedrich Hermann Löper, Josua Andreas Stückelberger, Philippe Wyss

The use of passivating contacts compatible with typical homojunction thermal processes is one of the most promising approaches to realizing high-efficiency silicon solar cells. In this work, we investigate an alternative rear-passivating contact targeting ...

Numerical Simulation of Temperature Dependence of MoOx Based SHJ Solar Cell

Christophe Ballif, Philipp Friedrich Hermann Löper, Stephanie Essig

Transition metal oxides based high efficiency silicon heterojunction (SHJ) solar cells have emerged as promising candidate due to their low manufacturing cost and avoidance of poisonous dopant gases. Temperature dependent J V curves in such solar cells cou ...
