Antoine Descoeudres,Loris Barraud,Stefaan De Wolf,Benjamin Strahm,D. Lachenal,C. Guerin,Zachary C. Holman,F. Zicarelli,Bénédicte Demaurex,Johannes P. Seif,Jakub Holovsky,Christophe Ballif +11 more
TL;DR: In this article, H2 plasma treatments are used during film deposition to improve the passivation of the a-Si:H layers, and 4 cm2 heterojunction solar cells were produced with industry compatible processes, yielding open-circuit voltages up to 725 mV and aperture area efficiencies up to 21%.
Journal ArticleDOI
Back-Contacted Silicon Heterojunction Solar Cells With Efficiency >21%
Andrea Tomasi,Bertrand Paviet-Salomon,D. Lachenal,Silvia Martin de Nicolas,Antoine Descoeudres,Jonas Geissbühler,Stefaan De Wolf,Christophe Ballif +7 more
TL;DR: In this paper, the authors report on the fabrication of back-contacted silicon heterojunction solar cells with conversion efficiencies above 21% using simple and size-scalable patterning methods.
Journal ArticleDOI
New Cell Metallization Patterns for Heterojunction Solar Cells Interconnected by the Smart Wire Connection Technology
P. Papet,L. Andreetta,D. Lachenal,Guillaume Wahli,J. Meixenberger,B. Legradic,W. Frammelsberger,Derk Bätzner,Benjamin Strahm,Yu Yao,Thomas Söderström +10 more
TL;DR: In this article, the authors present some of the latest cell metallization improvements of heterojunction solar cells dedicated to Smart Wire Connection Technology (SWCT) technology, including the use of interrupted front fingers instead of continuous fingers.
Journal ArticleDOI
Heterojunction and Passivated Contacts: A Simple Method to Extract Both n/tco and p/tco Contacts Resistivity
D. Lachenal,Derk Baetzner,W. Frammelsberger,B. Legradic,J. Meixenberger,P. Papet,Benjamin Strahm,Guillaume Wahli +7 more
TL;DR: In this paper, two TLM (Transfer Length Method) dedicated structures were presented to extract both the a-Si:H(n)/TCO and a-si:H (p)/TCo contact resistivity.
Proceedings ArticleDOI
