Influence of the Dopant Gas Precursor in P-Type Nanocrystalline Silicon Layers on the Performance of Front Junction Heterojunction Solar Cells

Christophe Ballif, Quentin Thomas Jeangros, Mathieu Gérard Boccard, Jean Cattin, Luca Massimiliano Antognini, Mario Joe Lehmann, Vincent Philippe Paratte, Laurie-Lou Senaud, Jan Haschke, Julie Amandine Dreon

Silicon heterojunction solar cells can employ p-type hydrogenated nanocrystalline silicon nc-Si:H(p) on their front side, since these can provide better transparency and contact resistance compared to hydrogenated p-type amorphous silicon layers. We invest ...

Influence of Light Soaking on Silicon Heterojunction Solar Cells With Various Architectures

Christophe Ballif, Mathieu Gérard Boccard, Matthieu Despeisse, Jean Cattin, Laurie-Lou Senaud, Bertrand Yves Paul Paviet-Salomon, Jan Haschke

In this article, we investigate the effect of prolonged light exposure on silicon heterojunction solar cells. We show that, although light exposure systematically improves solar cell efficiency in the case of devices using intrinsic and p-type layers with ...

Hole-Selective Front Contact Stack Enabling 24.1%-Efficient Silicon Heterojunction Solar Cells

Christophe Ballif, Sylvain Nicolay, Mathieu Gérard Boccard, Matthieu Despeisse, Jean Cattin, Luca Massimiliano Antognini, Vincent Philippe Paratte, Laurie-Lou Senaud, Bertrand Yves Paul Paviet-Salomon, Minh Truong, Jan Haschke, Julie Amandine Dreon, Wenjie Lin

The window-layer stack limits the efficiency of both-side-contacted silicon heterojunction solar cells. We discuss here the combination of several modifications to this stack to improve its optoelectronic performance. These include the introduction of a na ...
