One with TPO and the other with glass fiber reinforced TPO (GF TPO) encapsulant. Using fiber Braggs grating sensors (FBGS) attached to the cell, in situ temperature and strain are quantified during reliability tests in the form of thermal cycling from -40 degrees C to +85 degrees C. It was found that the temperature of the cell surface reaches -36 degrees C and +81 degrees C at its minimum and maximum respectively. The measured cell strain followed the same cycling behavior between tension and compression. The strain in the GF TPO based module was found to have a lower peak-to-peak (difference between max tension and compression) value. Also, a consistent difference between strain in parallel and perpendicular directions relative to the busbars was observed, with the latter one being larger. | Notes: | Van Dyck, R (corresponding author), Katholieke Univ Leuven, Leuven, Belgium.; Van Dyck, R (corresponding author), Hasselt Univ, Imo Imomec, Hasselt, Belgium.; Van Dyck, R (corresponding author), Imec, Genk, Belgium.; Van Dyck, R (corresponding author), EnergyVille, Genk, Belgium. | Document URI: | http://hdl.handle.net/1942/42657 | ISBN: | 978-1-6654-6059-0 | DOI: | 10.1109/PVSC48320.2023.10359569 | ISI #: | 001151676200045 | Rights: | Copyright 2024 IEEE - All rights reserved. | Category: | C1 | Type: | Proceedings Paper |
