Title: | 'There and Back again': Reusable Germanium Wafers with Ge-on-Nothing Structures for Triple-Junction Solar Cells | Authors: | DEPAUW, Valerie Courtois, Guillaume Cho, Jinyoun Dessein, Kristof Porret, Clement Loo, Roger |
Issue Date: | 2023 | Publisher: | IEEE | Source: | 2023 IEEE 50TH PHOTOVOLTAIC SPECIALISTS CONFERENCE, PVSC, IEEE, p. 1 -3 | Series/Report: | IEEE Photovoltaic Specialists Conference | Abstract: | Germanium-on-Nothing is proposed as a lift-off method to fabricate thin and lower-cost germanium templates for multijunction solar cells. This contribution presents how such foils, that are thickened epitaxially, can replace bulk wafers as III-V epitaxy seed, mechanical support, and bottom solar cell junction. Furthermore, by detaching large-area foils from reconditioned wafers, it demonstrates that the starting germanium wafer can be re-used and the recycling loop closed. | Notes: | Depauw, V (corresponding author), Imec, Leuven, Belgium.; Depauw, V (corresponding author), Univ Hasselt, Imec Imomec, Hasselt, Belgium.; Depauw, V (corresponding author), EnergyVille, Genk, Belgium. | Document URI: | http://hdl.handle.net/1942/42646 | ISBN: | 978-1-6654-6059-0 | DOI: | 10.1109/PVSC48320.2023.10359633 | ISI #: | 001151676200109 | Rights: | 2023 IEEE | Category: | C1 | Type: | Proceedings Paper |
